The structure of the suspension VAZ 2107. How to do the tuning and strengthening of the suspension of cars VAZ. Tuning chassis and suspension system VAZ

The VAZ-2107 car is the latest model produced by AvtoVAZ according to the so-called classic layout, when the car was driven to the rear wheels.

And since most of our motorists still prefer rear-wheel drive cars, the 2107 is still a popular car among the people.

The chassis of any car includes two main components of the suspension: front and rear wheels.

If we take into account the front suspension of the VAZ-2107, then it is more reliable than that of the VAZ-2108.

This is explained by the fact that component parts the front end hovers of the "Seven" are less than those of the "Eight" due to the drive to the rear wheels.

But at the same time, due to the same drive, the rear suspension is more complex, which means that there is a greater likelihood of a malfunction.

Front suspension device

The front suspension of the VAZ-2107 is independent. It consists of two levers, one of which is located at the top, the second at the bottom, as well as a telescopic shock absorber and a coil spring. A stabilizer completes the design lateral stability.

The lower arm with its axle is rigidly attached to the suspension cross member using bolts. Itself is also rigidly attached to the front side members.

The upper arm is attached to the mudguard post. But the lever does not have its own axis; it is a long bolt passing through the rack.

So that the levers can rotate around the axis, rubber-metal hinges (silent blocks) are used.

Ball joints are installed at the ends of both levers, to which the rounded fist having a journal for installing the wheel hub.

The coil spring is placed between the mudguard post and the lower arm. To prevent the spring from moving from its place, its ends are installed in special support cups.

The hydraulic shock absorber is installed inside the spring. With its body, the shock absorber is attached to the lower arm using a rubber-metal hinge.

The shock absorber rod is attached to the car body through rubber cushions. The anti-roll bar is fixed with its ends on the lower suspension arms, and in the middle - to the side members.

To exclude direct contact of the stabilizer with the side members, rubber cushions are installed between them.

Suspension malfunctions

Front suspension malfunctions include wear of rubber parts of the suspension, wear of ball joints is also possible. It is not uncommon for shock absorbers and springs to fail during operation.

In most cases, repairs to the front suspension of a VAZ 2107 can be done at home. But for this, to begin with, you will need to conduct a visual inspection and diagnosis of her condition.

To do this, it is advisable to drive the car onto an overpass or inspection pit. During the inspection, the condition of all rubber parts is determined, the presence of gaps in the ball joints, the absence of oil leaks from the shock absorber and the integrity of the spring are checked.

Checking the shock absorber

You can check the performance of the shock absorber in a simple way. To do this, you need to put good pressure on the wing of the car from above so that the shock absorber compresses and then releases. The shock absorber should immediately return to its original position and no longer make any oscillatory movements.

If a malfunction or severe wear of parts is found, the suspension is repaired. Since most suspension parts are not repaired, they are simply replaced.

To make repairs, all you need is a set of keys and heads, a jack and, in some cases, pullers.

Ball joints

To replace the ball joints, you must first remove the wheel and clean the suspension parts of the dirt. Then the jack is placed on the lower arm, they begin to raise the car. This is done in order to load the suspension.

With a key, unscrew the nut of the ball joint pin, to start with the top. Then the support pin is pressed out of the steering knuckle.

After the finger comes out of the fist, you need to unscrew the fastening of the ball joint and remove it together with the protective cover from the upper lever.

In place of the old ball joint, a new one is put and the assembly is carried out in the reverse order.

The lower ball joint is changed in the same way as the upper one. After replacing all ball joints, you need to contact the service station to check and, if necessary, adjust the angles.

Front suspension arms

To change the silent blocks on a car, you will need, in addition to keys, a special puller for them.

But in the case of the upper arm, it will need to be removed from the car, while replacing the silent blocks of the lower arm will not require this.

To remove the upper arm, you will first need to press out the pin of its ball joint from the steering knuckle.

Then you need to remove the bumper bracket bolt. After that, the nuts securing the axle of the upper arm are unscrewed, and the axle is removed, and the upper arm is removed from the car.

After removing the lever with a puller, the worn out silent blocks are removed and new ones are put in their place with the same puller.

The lever is installed in the reverse order. But, in order to install the ball bearing pin in place, you will need to load the suspension using a jack installed under the lower arm.

As mentioned, you do not need to remove the lower arm to replace the rubber-metal hinges on the lower arm.

It is enough to unscrew the nuts of the lever axle and remove the hinges using a puller. After that, new nuts are installed in their place and tightened.

Remove the lower arm only if it is damaged. But this happens very rarely.

Shock absorbers

In case of failure of the shock absorber, it is replaced. Moreover, even if only one shock absorber is broken, the second is also replaced.

To change the shock absorber, you first need to unscrew the nut securing its rod. After that, the washers installed on it, as well as the upper rubber cushion, are removed from the rod. And if the shock absorber knocks, then the reason for this is possible.

Then you need to unscrew the lower shock absorber mounting bracket from the lower arm. The broken shock absorber is removed through the technological hole in the lever.

Then you need to remove the mounting bracket from it. Installing a new shock absorber is performed in reverse order.

Everyone will be happy to ride in a car seat. With the breeze, on a soft seat. No shaking or bouncing. Stop. And what ensures such a smooth running of the machine? This is the job of the car suspension. Even VAZs have several types of them that are worth considering.

Front suspension VAZ 2107

On any car brand, the front wheel suspension is more complex than the rear damping system. This is due to the fact that the front wheels are steering, and unlike the strictly directed rear wheels, they have freedom of directional movement. In general, the front suspension of the VAZ 2107 chassis is quite powerful. It is designed in such a way for the possibility of driving on roads that do not have an asphalt surface. After all, this car is the latest version of the so-called classic VAZ series. It is the cheapest in the price range, and therefore the most popular among rural residents.

Front suspension device vaz 2107

Conventionally, the VAZ 2107 suspension can be divided into 4 nodes. Two triangular levers. The bases, both levers, are attached to the car body on movable mounts. Between the protruding tops of the "triangles-levers", a pivot lever connected to the steering is fixed by finger joints. Between the lower arm and the side member, a spring with a shock absorber inside passes through the opening of the upper arm.

To synchronize the suspension of the right and left sides, a lateral stability bar is installed between them, which, however, has decent freedom of position. It is attached to the lower arms. Basically, this is all a modification of the VAZ 2101 front suspension, then VAZ 2103, 2106. Preventive maintenance of the VAZ 2107 front suspension usually consists in replacing ball joints and rubber bushings.

Rear suspension VAZ 2107

The rear suspension of "classic" VAZ cars is directly connected to the rest of the chassis. In the rear suspension of the VAZ-2107, the driving rear axle is inscribed, which is connected to the car's engine through a cardan transmission and the rest of the transmission. The wheels are oriented strictly in the direction of the vehicle. These conditions determined the features of the rear suspension of the VAZ-2107. Like the front suspension, the rear is an upgraded version of the first VAZ model.

The figure below shows the rear suspension device of the VAZ-2107. Number 1 shows the thrust spring between the axle (4) and the vehicle body. Number 2, telescopic shock absorber damping sudden vibrations. Transverse reaction thrust 3, prevents the axle from shifting to the sides of the vehicle axis. Longitudinal rods 5 and 6 fix the position in the direction of travel. This arrangement of nodes allows you to compensate for road irregularities.

Front suspension VAZ-2110

Like any VAZ suspension, the tens' front suspension is independent. The front suspension device of the VAZ-2110 is more complicated than that of the classic models. This is due to the fact that the drive of the power unit goes through the gearbox to the front wheels. Therefore, the designers of VAZ had to solve the issue of not only the distribution of the load by the suspension, but also not to let it interfere with the operation of the drive. Here, too, the whole scheme is the result of a phased modernization of the front suspension, from the first version of the front-wheel drive model VAZ-2108. This variation, as the most successful, remained in the variations following the "ten".

Front suspension device VAZ-2110

The suspension kit includes the following components:

lower arm;
hub;
spherical bearing;
telescopic stand with spring;
brake disk;
wheel drive;
stabilizing transverse bar (on both wheels);
suspension arm with stretching.

It is the telescopic rack that plays a special role here. Now they are produced in several types. Liquid and gas racks. The principle of operation of the rack is based on a gradual, rather than abrupt, movement of the working rod in the body. This is achieved by in-cylinder bypass valves on the inner rod. Depending on the medium that the valves are bypassed, the struts are divided into hydraulic (liquid on oil) and gas. Usually the manufacturer installs cheaper hydraulic struts. One of the tuning positions of the VAZ-2110 chassis is just the replacement of liquid struts with gas ones. They are more effective and give stability to movement at any speed.

Rear suspension VAZ-2110

Racks are also used here. But since there are no unnecessary problems in the image of the rear-wheel drive, everything is somewhat simpler. The rear suspension includes the following units and parts:

The carrier beam is fixed to the car body with a movable joint. That is, the beam has a relative freedom of movement, like a lid hinged downward. The spring and shock absorber successfully dampen sharp vibrations, eliminating sharp impacts of the beam on the body. The main malfunctions of the rear suspension system are usually also primarily the malfunctions of the shock absorber strut. Also wear of rubber expansion joints in movable joints.

Attention! During any inspection of the undercarriage of the car, the mechanic-repairman must without fail check the condition of these parts.

Malfunctions of these components do not just cause discomfort from knocking. They contribute to the destruction of the body. A body repair pleasure is not cheap. It is better to replace the rubber grommet on the hinge or even the stand in a timely manner than to pay later bodywork.

Suspension of the chassis VAZ-2121 "Niva"

Russian SUV VAZ-2121 has an all-wheel drive. This was reflected in the suspension of the chassis of the car. It has its own characteristics and slight differences from other models.

Rear suspension Niva 2121

The rear suspension of the Niva axle itself is identical to the design of conventional classic VAZ models. However, the moving parts have a little more freedom of movement and are manufactured with a large margin of safety for confident movement on terrain where there is no road surface. The new design element is the device of the brake drive pressure regulator. Depending on the position of the machine and rear axle, a lever attached to the axle controls the opening of the rear brake valve. The rest of the suspension differs only in mobility and strength.

Front suspension VAZ-2121

The front wheel suspension is a little more complicated. The front wheels are both driving and steering wheels. Here, too, a larger angle of free movement of moving parts is provided. Therefore, for stabilization, an elastic bar is installed, which is attached to the body. The upper and lower support arms are made in an A-shape and are more reminiscent of the paired suspension arms of a front-wheel drive car than the classics. Despite the apparent fragility of the structure, its strength exceeds the strength of the "classical" structure due to the material and the form of rigidity calculated thoroughly. As in other suspensions, here it is necessary to carefully monitor the condition of the rubber bushings and ball joints.

Telescopic suspension strut VAZ

Telescopic struts replaced conventional shock absorbers with the advent of front-wheel drive VAZ vehicles. They perform the function of not only a shock absorber in the suspension system, but are also an important element of the suspension frame. If the shock absorber only mitigates the jerks when hitting bumps or bumps, the suspension strut mounted with the spring also prevents the suspension parts from moving in different directions. Keeps the suspension arms in position.

Therefore, all its parts are made of materials that are stronger than the shock absorber. Therefore, the price of the rack is much higher.

The device and principle of operation of the telescopic suspension strut

In fact, the rack resembles a medical syringe. The body is the barrel of such a syringe. A rod with a piston at the end moves inside. Only in the absence of an outlet, the fluid in the hydraulic struts is usually the spindle oil, which, with the help of valves built into the piston, smoothly moves to the top when compressed. When stretched also

smoothly moves back. Unlike the shock absorber, the suspension strut housing is equipped with cups for mating with a shock absorber spring, which provides additional suspension stability. In addition, depending on the type of rack, the lower attachments of the body to the suspension arms are arranged differently. The strut is not a repairable suspension unit. In the event of a malfunction, it must only be replaced.

Important! When replacing the rack, the spring is reinstalled on it. This can be done only with the help of a special tool - a spring clamping puller, in order to avoid serious injuries.

Brake system of VAZ cars

On the VAZ prototype, Fiat 124, the designers installed a disc brake system. It is ideal for highways and highways, those that are called federal in modern Russia. However, at that time, there were no roads of this level in the USSR. The vast majority of roads were of poor quality, and did not represent the possibility of high-speed movement. And in conditions of low and medium speeds, disc brakes did not perform well. Therefore, the drum type was adopted, where the semicircular pads were unclenched by hydraulics and pressed against the walls of the drum over a large area. So it was customary to install drum brakes on the classics. They did not become wise by going to front-wheel drive... The first "chisels" VAZ-2108, and after them and 2109, were equipped exclusively with drums.

Switching to disc brakes

However, time passed, and the situation with the roads began to improve markedly, the speed limit increased. The drum brakes were already performing poorly. Installing a full disc braking system, however, meant completely eliminating the sale of new models to customers in peripheral areas, where many roads still leave much to be desired. The "Solomon's decision" was made - the rear brakes remained drum, and the front ones were put on discs. Since then, this formula has been fixed on the VAZ. The only exception is Lada Kalina Sport. This special speed model is equipped with brake discs from the factory.

Tuning chassis and suspension system VAZ

There are no special improvements in tuning the suspension of any brand. A common practice in this direction is to replace drum brakes with disc brakes. But this should be done in the event that a general modernization of the engine and gearbox has been carried out. It is possible to replace some units with products made of lighter and stronger, correspondingly more expensive, material. Another tuning position is the manipulation of the length of the springs. Some owners, striving to give their car the look of a sports car, cut off 1-2 turns from the spring. Others, those who expect to carry heavy loads, on the contrary, "lift" the car with the help of special cushions under the springs, and even buy non-standard ones, with a large number of turns. Both options are unsafe. When cutting, "understating", the car loses a decent amount of depreciation, the shock absorber strut breaks down faster. The body is destroyed, control is deteriorating. When the body is lifted, the machine becomes less stable at high speeds and the risk of overturning increases. In general, tuning a suspension requires careful thought and serious consultation.

The video shows the repair of the front suspension of the VAZ-2107:

It is the front suspension that most often "takes the blows of fate" on itself, being the most loaded unit of the chassis of the car. That is why the care and timely inspection of its main components, their repair and replacement will be the key to successful driving of the VAZ 2107.

The entire front suspension of the "classic" is more reliable than the subsequent front-wheel drive modifications of the VAZ, since a car with rear-wheel drive has fewer parts in the front suspension, its device is more "economical".

The design of the front suspension has important components, without which a smooth ride of the car is impossible.

Let's describe the front suspension device on a VAZ 2107 car:

double wishbone suspension, there are upper and lower arms that exist independently; the upper one is secured through the mudguard strut with a long bolt, the lower one is bolted to the suspension cross member, which, in turn, is connected to the front spars.
silent blocks, or silent-running rubber-metal hinges. They are needed for the levers to turn. Replacement is required if worn.
ball joints, or simply "ball" - to them through the system of a steering knuckle with a trunnion, the wheel hub is ultimately installed.
the damping device includes a spring mounted in the cups and a hydraulic type shock absorber mounted inside the spring.
a bar (stabilizer) of lateral stability completes the list of basic devices.

The device and the most important parts of the VAZ 2107 suspension:

5 - knuckle pin; 9 - ball pin of the upper support; 10 - rotary fist; 13, 36 - upper and lower levers; 17 - support glass; 18 - shock absorber mounting cushions; 21 - upper support spring cup; 22 - axis of the upper lever; 29 - bracket for attaching the cross member to the spar; 30 - front suspension cross member; 33 - stabilizer bar; 34 - body spar; 37 - bolts of the lower arm axle; 40 - shock absorber;

This is what the suspension looks like from below. All structural elements are clearly visible (levers, spring, shock absorber, stability bar, ball, etc.).

What kind of malfunctions can the suspension have?

Drying and simple wear from time to time of rubber parts, anthers, liners, seals, the deterioration of ball bearings, wear of the cushions of the stability bar;
"Fatigue" of the metal, which can lead to breakage of springs and shock absorbers.

The front suspension, unlike the engine, was more fortunate, since it is easier to carry out repairs in a home garage, and the design of the suspension is open. This requires a flyover or an ordinary observation pit.

What can you tell when examining the suspension?

The state of wear, crumbling, dryness of all rubber parts;
It is determined how dry the shock absorber is and whether there is oil leakage from it, as well as evaluate its work. The test scheme is simple: you need to press sharply on the surface of the car wing and remove the load, that is, "release it sharply." A serviceable shock absorber returns the wing upward in one pass, without additional oscillation.
The integrity of all coils of the springs on the right and left sides;
The clearance in the ball joints is determined.

Replacing ball joints

The scheme of work (like all others) begins with cleaning the parts from dried dirt. It is necessary to make it a rule to clean all the elements at the bottom of the car, before starting diagnostics and repairs. It is most convenient to do this first with a jet of water from a nozzle of a portable car wash, and then dry it with compressed air.

To replace the ball joints, first remove the VAZ 2107 wheels.

The jacks for loading the lower part of the suspension rest against the lower arm, simulating the "load" on the suspension.

Unscrew the ball pin nut (for example, the top one).
A special rammer is used to separate the steering knuckle and the support pin;
The ball joint is turned out and removed in a protective case.
A new support is placed and assembly is carried out in the reverse order.

The lower support is also replaced. After that, the car is jacked up on the other side and the ball joints on the other side of the suspension are replaced.

After that, it is necessary to adjust the wheel alignment, this must be done at a service station at a special stand.

Silent - blocks.

Recall that the silent block is a connecting element in the VAZ 2107 suspension, as well as any other "classics" that has an elastic insert made of polyurethane or rubber in order to soften suspension shocks and vibrations. These parts absorb large shock loads.

The figure shows a diagram of fastening the silent block of the lower arm.

Because of this, the silent blocks are capable of wear and tear, as a result of which the camber - convergence is upset. It is desirable to change the silent blocks every 50-100 thousand km. Run.

Replacing shock absorbers

The shock absorber is a non-separable pair part. That is, if one of them fails, then both change.

In order to replace the shock absorber, you need to take the following steps:

We unscrew the fastening nut on the rod;
Remove the washers together with the upper cushion made of rubber;
We turn off the bracket with which the shock absorber is connected to the lower arm;
A broken shock absorber can be removed through the slot in the lever housing;
The bracket is removed from the shock absorber and a new shock absorber is installed in the reverse order.

Replacing a broken spring

To replace the spring (which also cannot be repaired), you need to remove the shock absorber, disconnect it from the lateral stability bar. After that, you need to loosen the screws of the lower lever, after which it is jacked up, then using a special puller we remove the ball finger.

VAZ 2107 in the original looks rather modest. The dynamic characteristics of the car are just as modest. Therefore, many car owners modify and improve almost all components and systems of the car: changes appearance, the interior becomes more comfortable, the engine power increases, etc.

Radical tuning of the VAZ 2107

You can use tuning to transform a serial sedan that rolled off the assembly line at the beginning of the 21st century into a car that vaguely resembles the original. Examples of professional tuning can be seen at various international competitions, for participation in which cars are specially altered and modified.

Tuning concept

The term tuning literally translates from English as tuning or adjustment. Any car can be tuned to such an extent that it becomes unrecognizable. Each owner modifies his VAZ 2107 in his own way, determining individually which components and parts need modification.

Before starting tuning both the car as a whole, and any component part, it is important to understand a number of simple requirements. The modernization of the machine must not contradict the Russian legislation and regulations. road traffic(SDA). First of all, this concerns external tuning of the body, replacement of wheels and disks, external and internal lighting. Everything that is attached to the sides and front of the machine must not: have parts protruding beyond the dimensions, be poorly welded or screwed on, contradict the requirements of UN Regulation No. 26.

There are three types of tuning.

Technical tuning: improving engine performance, revision of the gearbox, transmission, chassis. Sometimes this problem is solved radically - standard units and mechanisms are changed to units and mechanisms from other car brands.
Internal tuning: making changes to the interior of the cabin. The design of the front panel, seats, ceiling is changing, which are sheathed with fashionable materials, inserts are made of metal, expensive wood species, etc.
External tuning: body refinement. Airbrushing is applied to the body, body kits are installed, the configuration of thresholds, wheel arches, etc. changes.

An example of tuning a VAZ 2107

The appearance of the VAZ 2107 shown in the figure has changed a lot due to the unusual homemade front bumper, crate, front fenders and sills, painted green.

The ground clearance decreased from the factory 17 cm to 8-10 cm, which made the car look like a racing sports car and had a positive effect on stability and handling. The paint made the car visible in traffic. Thus, external tuning made the ride safer and gave the VAZ 2107 a memorable appearance.

Body tuning VAZ 2107

VAZ 2107 is ideal for external tuning for the following reasons.

The car initially has a discreet appearance.
On sale there is a wide selection of parts, accessories, tuning accessories at affordable prices.
The car does not have sophisticated electronics, automation, self-diagnosis systems that could be damaged during work.

Most often, external tuning is limited to window tinting and the installation of stylish rims. To give the body of the VAZ 2107 a streamlined shape is an almost impossible task. However, this is not necessary for the speed characteristics of the car. It is possible to reduce the force of air currents under the bottom by installing low-lowered spoilers, which harmoniously integrate with the body frame in the places where the sills and bumpers are installed.

You can give the car body a sporty look by:

Body kits and bumpers are made independently. It is very important to cut and bend them correctly. For this, you can use special computer programs.

Windshield tinting

In accordance with the traffic rules, it is recommended to tint the windshield only at the top with a lane width of no more than 14 cm. This will protect the driver's eyes from the sun's rays. For tinting you will need:

tint film 3 m long and 0.5 m wide;
glass detergent or shampoo;
rubber scraper to remove water;
nonwoven napkins;
marker;
a sharp thin knife (clerical can be used);
roulette;
spray bottle.

The tinting process itself is carried out as follows.

The windshield is removed from the body and released from the sealing rubber.
The glass is transferred to a bright, clean corner of the room, where there is no dust.
The glass on both sides is thoroughly washed with soapy water. Stubborn dirt can be removed with a solvent.
The tint film is applied to the outside of the glass and outlined with a marker with a tolerance of 5–7 mm.
The film is cut along the line with a sharp knife.
The protective layer is removed from the film.
The surfaces of the glass and the adhesive side of the film are moistened with soapy water.
The film is applied to a clean, damp surface. In this case, the formation of horizontal folds should be avoided.
The film is gently pressed with a plastic or rubber scraper from the center of the strip to the edges. Wrinkles are smoothed out at the same time. At the same time, it is advisable to warm up the film with a construction hairdryer. There should be no bubbles between the film and the glass. If they appear, they should be driven out with a scraper to the side that has not yet been glued, or pierced with a thin needle.
The glass is dried for several hours and installed on the car.

Headlight tuning

The most simple and affordable way tuning the headlights and rear lights of the VAZ 2107 is the replacement of standard bulbs with LED ones.

To do this, they usually use a special tape with spotlights glued to it. Thus, you can make original running lights, angel eyes, etc. You can also purchase already tuned front and fog lights and taillights from car dealerships.

Rear window tinting and decorative grille installation

If the car owner does not have experience in tinting, it is advisable to purchase the cheapest film for darkening. For rear window there are no restrictions on light transmission. Tinting is carried out without dismantling the glass, since it is glued to the sealing rubber. The work will require the same materials and tools as for the windshield. The film is glued from the inside in the following order.

The glass is washed with soapy water, and stubborn dirt is removed with a solvent.
The tint film is applied to the outer damp side of the glass.
The tinting is given the shape of the glass. To do this, the film is pressed against the glass and smoothed out under a stream of warm air from a building hair dryer. In order not to overheat the tint, the air temperature should not be too high. The hair dryer moves along the entire surface of the film, stopping in each place for 2-3 seconds.
The protective layer is removed from the tint film, and it is glued from the interior to the damp inner side glass. Since the film has taken the form of glass, it should fit snugly enough. Water from the tinting is expelled using a scraper.

Sometimes, instead of tinting, a decorative grill made of two-millimeter plastic is installed on the rear window, which can be purchased at a car dealership. For ease of installation, it consists of two halves and is easily attached to the rear window rubber seal from the outside. The grille can be painted to match the color of the car or left as is.

Installation of roll cage

The installation of a safety cage will help to protect the driver and passengers of the VAZ 2107 in extreme situations. The installation work of the frame is rather complicated. In order not to violate the geometry of the body, careful observation of dimensions, welding and fitting of pipes in the cabin using a hand-held power tool will be required.

Tuning of the salon VAZ 2107

In the original it looks very modest. The lack of frills provides the car owner with ample opportunities for tuning. Before radical internal tuning, the seats are removed from the cabin, the doors are dismantled and disassembled, the steering wheel, the dashboard and rear panels, as well as the floor and ceiling trim are removed.

Soundproofing of the salon VAZ 2107

Internal tuning should begin with the installation of new noise insulation, without which it makes no sense to install a high-quality audio system. During the installation process, preliminary preparation is made for tuning all elements of the cabin. Depending on the readiness of the body surfaces, the insulation can be installed either in parts or completely. First, the outer wheel arches and the bottom of the car are processed, then the trunk, the hood, the floor and ceiling of the cabin, the doors and the dashboard. After dismantling the engine, the bulkhead in the engine compartment is insulated.

Required tools and materials

For noise insulation you will need:

set of open-end wrenches;
set of spanner keys;
a set of sockets with an extension and a ratchet;
construction hair dryer;
a set of screwdrivers with different blade shapes;
vibration-insulating material on a mastic basis ("Vibroplast Gold" or "Silver") with a thickness of 4 or 8 mm;
Shumka (products of the enterprises "Shumoff" and "StandartPlast").

Soundproofing the floor

The soundproofing of the floor is carried out as follows:

The fasteners are unscrewed and the front and rear seats are removed.
The factory covering is removed from the floor.
The floor is degreased and treated with special mastic.
The floor is covered with soundproofing material.

Experts advise to lay thin Shumka in several layers without gaps and gaps. Sound insulation is more effective than laying thick material in one layer.

Front panel tuning

There are a lot of opportunities for tuning the front panel of the VAZ 2107. You can cover it with expensive material, make inserts of aluminum, chrome or precious woods. For appliances, you can make LED backlight or install the GF 608 Gamma panel with on-board computer... The steering wheel can be replaced with an analogue from a foreign car, covered with leather or other material.

Obviously before tuning dashboard need to be dismantled.

Replacing the interior trim and seats

You can effectively change the look of the cabin by replacing the upholstery of the seats, headlining, front and rear panels, doors with more modern and practical materials. At the same time, it is not recommended to use fleecy materials (phlox, carpet, etc.). When cleaning such surfaces with a vacuum cleaner, their surface will quickly lose its original appearance. For self replacement upholstery of the seats will require a sewing machine and the ability to handle it.

On sale there are special inexpensive kits for tuning the VAZ 2107 interior, consisting of plastic decorative overlays for the dashboard, sun visors, armrests, door cards, acoustic grilles, etc. Such a set can be matched to the color of the car and choose different versions.

Seat upholstery

The ideal option is to install more modern seats in the VAZ 2107 salon. Chairs from Toyota corolla produced in 1993-1998, the fastenings of which coincide with regular bolts seats VAZ 2107. However, it is quite expensive.

To tighten the seats you will need:

material (fabric or leather) for upholstery;
foam rubber;
glue "Moment" or similar;
electrical tape or tape;
sewing machine;
thick needle;
threads of a suitable color;
sharp knife;
awl;
set of wrenches;
hammer;
Screwdriver Set.

The work is carried out in the following order:

The front seat is removed from the rails and placed on a flat surface.
The old paneling is unstitched at the seams. In doing so, it is necessary to prevent damage to the edging.
The places where the casing is glued to the cardboard inserts are wetted with gasoline.
The old upholstery is neatly pulled off the backrest and seat cushion.
A pattern is made from a new material along the contour of the old sheathing with scissors.
On a sewing machine, the upholstery and edging are sewn with a double stitch. Depending on the material, the joints can be manually stitched, glued or heat welded.
Foam rubber and sagging seat springs are changing.
The new upholstery is carefully pulled over the back and cushion of the front seat.

The rear seat is pulled in the same way.

The installation of new door cards will also noticeably refresh the interior of the VAZ 2107. This is quite simple to do. As new cards, you can use plastic wood-like pads. Alternatively, you can buy a set of various inserts for the VAZ 2107 interior in the store.

Headliner trim

Some car owners attach hardboard to the ceiling of the VAZ 2107 cabin and already glue the carpet onto it. It is quite time consuming and laborious, but the result is very effective. Before starting work, the windshield and rear windows are dismantled.

Sometimes the standard upholstery is changed to leather or some other material. However, before that, you should strengthen the soundproofing of the ceiling. For this:

the factory Shumka is carefully removed;
the metal surface of the ceiling is degreased;
a vibration damper is glued to the degreased surface (experts recommend using a construction hair dryer);
a splan layer is glued to the vibration damper;
the surface is covered with factory shumkoy.

Other possibilities of internal tuning VAZ 2107

The tuning of the VAZ 2107 salon can be supplemented with:

replacement or modification of sun visors and rear-view mirrors;
changing the interior lighting with the installation of footlights;
installation of a new radio and acoustic system;
installation of electric windows;
replacement of regular rugs with decorative;
modernization of other parts, devices and devices.

VAZ 2107 engine tuning

The manufacturer installed on the VAZ 2107:

carburetor engines with a volume of 1.2 and 1.3 liters;
injection engines with a volume of 1.5 and 1.6 liters.

The most common types of tuning power units are:

an increase in the working volume of the combustion chambers;
replacement of the camshaft;
installation air filter zero resistance;
alteration of the exhaust system to a straight-through muffler.

The greatest effect is obtained by installing a turbo kit on the engine.

Ways to increase engine power VAZ 2107

You can increase the power of the VAZ 2107 engine in the following ways.

Cylinder head tuning. Due to this, the power can be increased by 15–20 liters. With. Since the head is made of cast iron, all the operations for its completion are quite elephantine and time consuming.
Carburetor tuning. The diameters of air and fuel jets are changed, enlarged diffusers are installed.
Installation of two or four carburetors.
Installation of a turbocharger consisting of a compressor and a turbine.
Boring cylinders to increase their diameter.
Installing forged lightweight pistons instead of cast ones.
Replacing the standard air filter with a zero resistance filter.

On VAZ 2107 injection models, it is recommended to carry out software chip tuning. This will not only optimize the performance of the engine, but also normalize the operation of the electronic control unit. The effect will be maximum if chip tuning is performed on a serviceable engine that has passed a full technical inspection.

Tuning of the exhaust system VAZ 2107

Some car owners make the engine sound louder to sound like the growl of a sports car. For this, the catalyst is replaced with a special flame arrester. Other owners of the VAZ 2107 believe that tuning the exhaust system is justified if the result is an increase in engine power. When assessing the feasibility of such measures, it should be borne in mind that improper installation will lead to an increase in fuel consumption and a deterioration performance characteristics car. Therefore, the work on tuning the exhaust system should be entrusted to professionals.

When tuning the exhaust system, do not forget that the maximum engine sound level should not be louder than 96 dB. Alteration of the exhaust gas evacuation devices cannot impair the environmental class of the engine.

Tuning of the exhaust manifold and the intake pipe

For better purging of exhaust gases, extreme sportsmen change the standard exhaust manifold for a StinGer spider complete with a double intake pipe (pants) made of stainless steel. This allows for an increase in power at high revs by about 9 hp. With. In this case, the formula for the exit of exhaust gases "4-2-1" does not change.

Since the inner walls of the StinGer are smoother, installing such a manifold will increase the flue gas efficiency and increase the power by maximum speed 9 liters. With

The flat surfaces of the StinGer manifold flanges ensure that they fit snugly against the cylinder head and pants. However, the new upstream pipe does not have a threaded seat for the oxygen sensor. Therefore, if necessary, a nut is welded on this pipe in front of the catalyst, into which the sensor is installed.

Since the pants end with a flange, the resonator of the injection model is attached without problems. However, on the carburetor VAZ 2107, this unit is made differently, therefore, it is better to immediately install a resonator from an injection engine on such a car.

Installing a straight-through muffler

A standard VAZ 2107 muffler consists of two pipes welded at different angles and lined with a non-combustible mineral wool filler, which reduces the speed of exhaust gases and softens the exhaust. To increase the volume of the exhaust and make the exhaust flow straight, the exhaust system is audiotuned. Instead of a conventional muffler, a direct-flow, do-it-yourself muffler is installed.

In a straight-through muffler, the exhaust gases do not make turns, which slow down the speed, and are additional resistance that reduces engine power

Thus, with the help of tuning, you can turn the VAZ 2107 into a completely new car... In accordance with the wishes of the car owner, almost any units and parts, including the engine, are being finalized. Tuning items are commercially available, and it is quite easy to do most of the work, carefully following the instructions of the professionals.

The suspension is necessary for a VAZ 2107 car so that movement on it is not only safe, but also comfortable. The suspension device is usually presented to a novice car enthusiast as a very complex scheme, but let's take a closer look at it.

What is the suspension arrangement?

The suspension on the VAZ 2107 is represented by a set of assemblies from various parts and rotating mechanisms.

The main elements among them should be called:

elastic parts, the work of which we can feel when driving on uneven terrain;
guide parts responsible for the trajectory of the wheels;
shock absorbing parts or simply shock absorbers. They help to reduce excessive vibrations of the car body resulting from the action of the road surface.

Suspension functions

The unique suspension device on the VAZ 2107 plays an important role in the design of the car:

it connects the body itself and the wheels to each other;
provides the highest possible smooth running even under the worst road conditions;
"Informs" the driver about the quality of the road by transferring the emerging force to the bearing system.

Suspension and its structure

The front suspension mechanism of the VAZ 2107 car is called "independent". It has a double wishbone and a cylindrical spring, shock absorber parts with a telescopic structure, as well as a stabilizer with a special lateral stability function.

The base with the lower arms is screwed to the cross member connecting to the front side member. There are washers along with special spacers next to the cross member and the lower base. It is they who help determine the angle of the axle when turning the rear wheels.

The upper arms are bolted together. Its levers rotate, as they have a hinge device. The levers have a steering knuckle (there is a brake disc on it) along with a wheel hub.

Front suspension springs are cylindrical. Their upper edge touches the mudguard strut, and the lower edge abuts against the support bowl from the lever (lower). All this will be clearly shown by the diagram.

The springs themselves contain shock-absorbing elements. They are connected to the body of the VAZ 2107 using rubber pads. They have a connection with the lug of the case thanks to the lower lever.

A steel spring anti-roll bar serves to prevent the vehicle from skidding. Its attachment at the front is carried out through rubber pads applied to the front side members, and at the rear using the lower suspension arms.

The suspension diagram for the VAZ 2107 is presented below.
