Tuning the suspension of the VAZ-2107

Tuning the rear suspension of a VAZ classic model involves improving the stock suspension of the car and eliminating its past shortcomings such as strong roll in corners and skidding of the car, especially at high speed. Most car owners invest a lot of money in this type of work, since this is a rather labor-intensive and responsible process, because the invention of an already created “bicycle” can result in negative consequences.

The car owner needs to answer two basic questions: “What does the owner want to achieve by tuning the rear suspension?” and “How exactly does he want to do this?”

First you need to delve into the structure of the rear suspension of classic VAZ cars, understand its advantages and disadvantages. The suspension on this car is dependent, spring. For vertical stability, it has four reaction rods, and for horizontal stability, it has a lateral stability rod or, as it is also called, a “Panhard rod.” The advantages of such a suspension include the fact that, due to the springs, it is softer than a leaf spring, and when the car is loaded, the suspension does not allow it to sag much, and when driving on an uneven road, thanks to the reaction rods, a clear vertical stroke of the suspension occurs.

Among the disadvantages, it is worth noting that at high speed the car is subject to skidding, namely, its rear part is driven, this is especially evident when driving on a slippery road. Also, when turning, a large roll occurs, it turns out that when entering a turn the driver has to slow down in order to successfully fit into it.

Options for tuning the VAZ-2107 suspension with your own hands

The first element that people want to upgrade in a car is the suspension.
The car has problems, so not everyone likes it. Using the example of a VAZ-2107 car, let's look at suspension tuning and how to do it yourself. The disadvantage of the suspension of this car model is the softness of the connecting parts of the chassis and body, especially at the rear. To make it tougher, car enthusiasts do their own tuning, replacing factory parts with more powerful elements.

You will also have to make adjustments to the front suspension, since by increasing the rigidity of only the rear axle, an imbalance appears. Let's look at what work needs to be done so that the car's handling is not affected.

INSTALLATION OF READY TUNING DEVICES ON A VAZ-2107

As mentioned earlier, specialized stores and service centers sell a large number of ready-made kits for tuning the VAZ-2107 panel. The configuration, dimensions and connectors of finished electrical appliances intended for modernization are practically no different from the analogues installed on the standard version.

The work is not a particularly complicated process: it is almost impossible to mix up the connection points, all connectors differ in shape and simply do not fit into places not intended for them.

The only nuance regarding tuning the tidy using a ready-made kit is the procedure for installing the speedometer cable. The standard device provides for its free installation with a certain amount of play - the braid allows you to freely remove the element, moving it towards the car's interior. During dismantling, the cable may come out of the coupling with the speedometer drive on the gearbox, as a result of which the latter element simply will not function. Before fastening the nut, you should carefully inspect the position of the cable and make sure it is in good condition.

Rear suspension upgrade

To do this, change the following spare parts:

springs;
silent blocks;
shock absorbers;
rubber bumpers.

Rear suspension of VAZ-2107

It is considered a classic to replace factory springs with those intended for the VAZ-2102(04) or VAZ Niva. These parts fit well into the circuitry here, but are also stiffer and more powerful. However, if the Niva’s springs are the same size as those of the VAZ-2107, then these spare parts from the VAZ-2102(04) lift the rear of the car, which is undesirable. In this case, in order to reduce the ground clearance, you have to remove one or two turns yourself.

The front suspension of this model takes on the largest part of the mechanical load when driving. Therefore, owners of the VAZ-2107 model pay a lot of attention to it when repairing and tuning the car.

INDEPENDENT PRODUCTION OF INSTRUMENT DIRECTORS AND STICKERS

Tuning the VAZ-2107 torpedo can be done using homemade elements: arrows and stickers. Such things are bought on the shelves of specialized retail outlets, or made with your own hands according to individual designer patterns. The last option is a little more difficult to implement and guarantees a greater percentage of uniqueness of the design.

When replacing arrows and stickers, you should pay attention to such nuances as:

Before installing a new scale, the surface to be treated should be cleaned and degreased;
When setting the arrows, watch your movements: these are very fragile elements that are damaged even from weak mechanical influences;
You should pay close attention to the correct installation of the arrows: incorrect installation will lead to the instruments visually displaying erroneous values.

Please note: the arrows can be easily removed using pliers. When pulling out the element, try to move carefully so as not to bend the fastening axis.

A popular type of tuning is installing a sports suspension.

To provide better handling and stability at high speed, the following changes are made to the suspension:

gas-oil shock absorbers are installed;
springs are lowered;
the stroke of the shock absorber rod is limited;
a suspension is installed with the ability to adjust ground clearance (with remote cameras or screws);
triangular levers are mounted that change the castor - the angle of longitudinal inclination of the axis along which the wheel rotates. The larger it is, the better the car's handling.

This completes the modernization of the car's suspension.

Do-it-yourself tuning

In this case, you can save a lot of money. You will also have to spend a lot of time. But the panel will look completely unique.

First of all, you need to decide on the design. It makes sense to look at the photographs, of which there are quite a lot on the Internet.

The easiest way is this:

replace factory needles on instruments;
install new stickers with scales;
change the lighting.

All these require only accuracy and basic knowledge of electrical engineering. At the same time, you can order a set of arrows and backgrounds for instruments in any studio that specializes in finishing cars. The professionals there are able to make them according to your design or develop it themselves. This will, of course, cost a pretty penny.

Tuning the suspension of the VAZ 2107

Despite the availability of foreign-made cars for domestic motorists, the fleet of vehicles produced by the Russian Automotive Industry is quite large. And various models of Zhiguli are especially popular among our compatriots. That is why the problem of tuning in general, and suspension tuning in particular, does not lose its relevance.

Tuning the front suspension of the VAZ 2107

Restyling of the “Seven” suspension, however, like the tuning of the “VAZ 2106” suspension, usually pursues one main goal - to make an analogue of the sports suspension. And the main means of achieving it is to replace the main suspension elements with modern options. First of all, these are shock absorbers and springs. Tuning masters recommend parts produced on the Eibach and Koni conveyors for this purpose.

The main advantage of spare parts from these brands is a high level of quality coupled with an affordable price. In addition, the installation of these elements does not imply alteration of standard seats.

The next element that is frequently replaced during the modernization process is rubber products, or silent blocks. For example, tuning the VAZ 2106 suspension is rarely complete without installing silent blocks made of polyurethane.

Removing the instrument panel

This is the first stage of any tuning, which will have to be performed in all cases.
Before you begin, please read the instructions. The procedure is as follows:

disconnect the negative terminal from the battery;
remove all heater handles on the panel (tread carefully - they break easily);
unscrew the nut holding the lever in place that resets the readings;
push it inside;
remove the plugs from the screws securing the dismantled element;
unscrew them with a screwdriver;
remove the panel from the elephant.

Tuning of VAZ 2109 suspensions

Modernization of the suspension systems of domestic "eights" and "nines", as well as tuning of the VAZ 2110 suspension, basically does not have any fundamental differences from the changes described above. The restyling procedure includes:

Installation of front air shock absorbers.
Replacing the anti-roll bar.
Changing the front wheel alignment angles:

— the longitudinal inclination angle increases; — “camber” is set to a negative value.

Installation of spacers between the “cups” of the upper supports on the front pillars.

The result of such tuning is a significant increase in the degree of rigidity of the car suspension, which eliminates the occurrence of large roll angles when turning, “yaw” and increases the controllability of the vehicle.

Let's start with the backlight

In principle, where exactly you start tuning the VAZ 2107 instrument panel does not matter. You can first replace the arrows or scales, and only then deal with the backlight. But we will start the description with the backlight, since it really leaves much to be desired.

Important information! The main stages of tuning the VAZ 2107 instrument panel:

removing the instrument panel;
replacement (refinement of scales and hands);
installation of LED lighting;
installation of a finished dashboard.

Most often, when tuning, car enthusiasts choose LED lighting for instruments and panels. It gives the interior a more modern look. To modernize the dashboard, you can use 10 LEDs and connect them with special cables. Next, you need to cut off the LED heads and treat their surface with sandpaper for a softer glow. You can place the LEDs as you wish.

Alternatively, there are 4 LEDs around the largest scale in the corners, one between two small sensors. The rest are located at your discretion. Once you've completed this job, it's a good idea to be sure to connect the entire system and look at the results before you put the panel back on. As for the illumination of the arrow on the instrument panel, LEDs can also be used here. By the way, you can also replace the arrows themselves. To do this, use a ready-made set or make them from plexiglass on a machine. The second option is much more labor-intensive. But you can make them unique.

Self-tuning of VAZ 2114 suspension

Upgrading the suspension is, first of all, necessary for car owners who prefer a dynamic driving style, including frequent maneuvering.

a) Replacing shock absorbers. The best choice for replacing standard shock absorbers will be gas-hydraulic devices. They will provide almost perfect response to uneven road surfaces. The only negative point that arises during their operation is heating of the cylinder walls when driving at high speeds.

b) Modernization of springs. These elements provide a smooth ride and excellent handling of the car. A prerequisite when choosing springs is the presence of a reduction coefficient on the packaging and the identity of the brand of new and standard elements.

c) Replacement of bushings. Bushings and silent blocks made of polyurethane, together with the installation of a stabilizer bar, will provide a high level of resistance to deforming loads.

Suspension device VAZ 2107

The Seven, like its predecessors, has a double wishbone suspension with independent wishbones. The upper arms are attached to the mudguard strut, the lower arms are attached to the cross member holding the front side members.

For free rotation of the levers on the axle, silent blocks (rubber-metal bushings) are used, thanks to which the lever remains mobile, but does not “play” on the axle and does not knock.

The wheel hub is mounted on ball joints, which allow it to rotate freely along a vertical axis.

A smooth ride when driving over uneven surfaces is ensured by springs and shock absorbers that dampen vibrations.

The simplest option

Owners of the “Seven” injector who have a certain amount of money and do not have enough free time should pay attention to ready-made kits containing everything necessary for tuning. Each set comes with instructions, following which it will not be difficult to improve the functionality and appearance of the dashboard.

But for those who are not looking for easy ways and dream of a completely unique design, the method described above is definitely not suitable.

Possible malfunctions of the VAZ 2107 suspension

Suspension faults can be divided into groups:

drying out and wear of rubber parts: boots, bushings;
wear of liners and seals, which causes failure of ball joints, anti-roll bar cushions, silent blocks;
metal fatigue, leading to breakage of shock absorbers, springs and even levers.

Checking and repairing the front suspension is a fairly simple operation. They are carried out on an inspection pit or a lift.

Possibilities of tuning the front suspension of the VAZ 2107

The design of the VAZ 2107, especially the suspension, is not far removed from the outdated FIAT 124. That is why suspension tuning is so popular - owners are trying to improve its characteristics. The purposes for which the front suspension of the VAZ 2107 is tuned are as follows:

improving the smoothness of the ride;
improved handling;
increased stability at high speeds;
increasing the reliability and durability of components and parts.

One of the simple and effective ways is to install high-quality components from foreign manufacturers. This is especially true of shock absorbers, a wide selection of which allows you to solve many problems and customize the “seven” for yourself, making its ride either softer and smoother, or stiffer but stable at high speeds.

Below we will consider the most popular types of tuning.

Installation of sports suspension

To improve stability and handling at high speed, the following changes can be made to the suspension:

How to Increase Engine Power in a VAZ 2107 Injector

Anyone who owns a car and, for economic or other reasons, is obliged to drive a classic VAZ car on the road, often dreams of increasing the power of their own engine. To do this, you will need a huge number of circumstances, but the main ones are only three:

lack of power on long stretches, overtaking over long distances and carts often subject to reduced visibility;
the desire to make a “sports start” at a traffic light in order to stop or catch up with an overly impudent foreign car;
Show off your “coolness” and motor knowledge like 5 fingers” to your friends.

These preconditions are unfortunately quite useful because the first one can actually save lives according to the criteria where sudden acceleration can save a life, let's see how to tune a VAZ 2107 engine.

Adjustment. This is not only an uncontrolled increase in power, but also an opportunity to obtain the necessary characteristics for yourself.

Stages of setting up a motor at home:

Work to increase total power:

complete cylinder head;
changing the carburetor diameter of fuel and air injectors;
installation of enlarged diffusers in the carburetor;
turbocharger unit (compressor and turbine)
cylinder hole to increase volume

This step is usually called tuning, but it is simply the restoration of various systems that change these, in other words, other characteristics.

Adjusts maximum power at “upper” or “lower” speed. These include aerobatics, such as adjusting valve timing, adjusting the operation of all systems to obtain the appropriate values.

The car owner independently makes the following adjustments to the VAZ 2107 engine:

Acoustic tube injector for VAZ 2107. Is this required or not?

Cylinder head components: grooves in the intake and exhaust manifold channels, combination of wells. This process is quite labor intensive as it involves drilling into cast iron, but the effect of increasing power is 15 to 20 horsepower even if you do nothing.
Carburetor adjustment: increasing the size of the diffusers from 3.5 to 4.5, replacing air and fuel injectors, removing the vacuum throttle spring, mechanically replacing the vacuum drive by installing a wire, replacing the pump from 30 to 40.
Installing the air filter yourself with zero resistance (shells). At the same time, the engine at high speeds develops the best “gas response”; air pressure does not “slow down its breathing”. Thus, the zero-resistance filter looks assembled.

The disadvantages are that the filter requires some maintenance and can create additional noise.

Installing several (at least 2) carburetors on the engine. It is clear that in the VAZ 2107 the paired working cylinders are “friends”, so cylinders 3, 2 and 3 can be obtained in the form of an enriched mixture near the center. This is confirmed by the darker pistons in cylinders 1 and 4; the pistons are lighter. The mixture is leaner. To even out the flow of consistency and balance it, install two carburetors, one for several cylinders. Consequently, excellent traction is achieved both at low speeds and with a significant increase in power at high speeds.

Replace the camshaft yourself, depending on the length of the project you want to add engine power to: at lower or higher speeds. A conventional shaft distributes power evenly across the entire spectrum. But wide-phase shafts not only lift the valves, but also the engine operates at maximum speed. The smallest phase axis moves the gearbox into lower gears. That's why there are top, universal and bottom (bottom) shafts.

The bottom cam is good for towing, off-roading and rescuing "elderly people". The horse begins to "run" at 3200 rpm, being "dead" at this low speed and consuming a lot of fuel. This is a sportier and purely urban option.

How to properly tune and strengthen the suspension of VAZ cars

You should not think that the installation of additional elements of the car’s design is carried out exclusively by tuning enthusiasts.

Many car owners often do this in order to give their domestic car, for example a VAZ car, better driving characteristics.

Today we will talk about the main types of modifications to the suspension of VAZ 2107, 2109, 2110, 2106, 2112, 2101,2105 cars made by drivers, and we will also evaluate the feasibility of their installation.

Here are the basic principles of the correct approach to tuning the suspension of VAZ cars and other domestic cars, as well as ways to strengthen it.

And although the procedure for installing individual additional suspension parts is the same for many VAZ cars, you still need to understand that their installation on the VAZ 2101 and 2112 will be different.

16-valve engine for the "seven"

The VAZ 2107 is equipped with an 8-valve power unit from the factory. Of course, one of the easiest tuning methods is to replace it with a 16-valve engine. Traditionally, the engine from the VAZ 2112 is chosen, since it is almost identical in size to the engine from the VAZ 2107 and meets all the requirements for power and efficiency.

Installation of a 16-valve engine on a “seven” is carried out according to the following algorithm:

Prepare the motor for installation. To do this, you need to remove the flywheel and grind the crown from the inside. Turning is necessary so that the starter parts are more easily connected to the flywheel clutch. In addition to turning, you will need to replace the input shaft bearing with a bearing from 2112, otherwise the new engine simply will not fit into the seat.

Video: installation procedure

A 16-valve engine instead of an 8-valve is the best option for those drivers who want to feel quick feedback from their actions while driving, optimize engine power and the resource of the entire car as a whole.

Thus, any type of tuning of the VAZ 2107 engine can turn the car into a faster and more durable model. However, when performing any type of work, you must adhere to regulations and safety precautions; otherwise, it is better to contact experienced specialists.

Front strut

The most popular element, widely used by many owners of Russian cars, is the front cross brace.

Its installation is carried out in the area of the upper shock absorber supports, by securing it between the strut cups.

The main purpose of this part is to increase the angular rigidity of the body and improve the handling quality of the vehicle.

In addition, the presence of a spacer helps eliminate the “floating” geometry of the suspension arms, which occurs as a result of strong impacts on road potholes or uneven surfaces.

The main reason why many car enthusiasts, in particular owners of VAZ cars, make such modifications is due to insufficient body rigidity, which contributes to deterioration of handling, a feeling of “sluggish” steering and excessive roll that occurs when performing maneuvers.

This is detected only when driving at high speeds, mainly associated with trips on country roads.

Console tuning

Tuning the VAZ-2107 console is an optimization of the front panel, as a result of which many useful features and advantages can appear in the car, such as a new tape recorder, clock or cigarette lighter. Refinement of the beard of the VAZ-2107 allows you to make the vehicle more original and functional. Anyone can, through simple improvements, install a player, a modern clock, a USB socket, devices for monitoring the electrical network and small “pockets” for small items in the car.

Among the main tools, without which tuning the standard beard of a VAZ-2107 is impossible, it is worth noting: an electric jigsaw and drill; "grinder"; locksmith corner; a simple pencil; ruler; glue and stapler for furniture.

Do-it-yourself tuning of the VAZ-2107 beard may involve the manufacture of a new panel, which will initially have special areas for the location of switches and indicators. The easiest way to tune the console is with ordinary plywood with a thickness of about 6 mm. It is advisable to use artificial leather as finishing materials, which perfectly matches the color with the rest of the interior elements. Recently, car owners have even adapted to introducing carbon fiber.

Tuning the VAZ-2107 beard can be done with the help of a comprehensive modernization, which will “radically” change the interior of the car. Replacement on doors and other interior elements can be made using carbon fiber and leatherette. The new console will need to be positioned in place of the factory fixture, which must first be dismantled. By removing a standard beard, the motorist can quickly take measurements to further create drawings.

Auxiliary powertrain support

The purpose of supplementing the standard motor mounts with another auxiliary module is to minimize the amplitude vibrations of the engine during sudden braking, acceleration and overcoming road hills or potholes.

Its presence eliminates the so-called “pecking” - inertial phenomena that occur during vehicle operation.

The presence of an auxiliary support also prevents spontaneous disengagement of the transmission gears.

This significantly reduces the risk of unpleasant incidents that directly affect safety.

Typically, it is difficult to install this component yourself.

A certain skill is required, which the average car enthusiast does not always have.

Separately, we will say that some engine models require the installation of a fourth support only after moving the ignition unit.

This, on the one hand, is an additional difficulty, but, on the other hand, it significantly improves the operating conditions of the electronic module, moving it away from the road, thereby reducing the amount of dirt that gets on it.

An additional support for the power unit is often installed during tuning of the suspension of VAZ 2109, 2110 cars.

New lighting or tuning of the instrument panel of the VAZ 2107

Almost every driver of a VAZ 2107 (seven) dreams of changing the dashboard because it is too dull, simple and monotonous. And so they transform the panel in different ways, such as stickers and other accessories that can be purchased at an auto parts store. And so we will tell you one of the ways to change the panel.

Removing the dashboard panel

At the very beginning, you will need to use a screwdriver to carefully remove the sliders that are needed to control the stove. After this, on the right, near the emergency light button, unscrew the nut and washer. To the right of the sliders that were removed, there is a plug that also needs to be removed, and then unscrew the screw there. After all the steps, we can safely remove the dashboard and unscrew the clamping nut, after which we can remove the speedometer cable.

We disconnect all the wiring from the panel and now it is removed from the panel in your hands.

After that, we can remove the hands, but be careful, because they are quite fragile, and therefore you need to carefully remove them so as not to bend/break the hands and the saddle where they sit. Quite often, you have to force them out towards the parallel pin.

Rear beam stabilizer bar

The element's purpose is to reduce the lateral roll of the car, improve the interaction of the wheels with the road surface when cornering, as well as distribute the load between the rear shock absorbers when one of the wheels drives over uneven surfaces.

The fact is that when you hit deep potholes, extremely strong suspension occurs, often causing the rear shock absorber strut rod to be pulled out.

When working in compression, the shock absorber, on the contrary, is overly susceptible to breakdown, which seriously affects its durability.

This does not happen with amplification. The resulting force is distributed between both wheels with an approximate ratio of 3 to 2, which has a positive effect on the quality of control and the reliability of the suspension elements.

The stabilization bar is installed directly on the rear beam of front-wheel drive models of domestic VAZ and other cars.

Installing a beam reinforcement should not cause any problems for most drivers. To do this, you need to use a trestle or inspection hole, and then fasten the rod to the beam according to the instructions.

The only difficulty that may arise is the need to drill eight holes in the beam housing.

Reinforced front stabilizer

The front stabilizer of increased rigidity is a means designed to significantly improve the quality of vehicle handling.

Its main difference from the standard part is the harder rubber bushings located at the attachment points.

The nuance of using such an element is that it improves the ride on smooth asphalt areas, but if you have to drive along a bumpy country road, vibrations in the steering wheel will become a real punishment.

Even the slightest impact will be completely transmitted to the steering wheel, which will significantly complicate the driver’s life.

A reinforced stabilizer is quite expensive, and we consider the need for its installation doubtful.

Perhaps only sports car models participating in road competitions need it. The average car enthusiast does not need this modification, especially when tuning the VAZ suspension.
