One of the simplest sports tuning options is suspension upgrades. This allows for a relatively small price to significantly change the behavior of the car. The best options for undercarriage parts that have the greatest efficiency include screw suspensions.

Definition

This part is a structure that combines a spring and a shock absorber. Also called coilover and adjustable suspension.

Types

There are two ways to install these parts.

Only thread and coil spring can be replaced. The suspension in this case may be ineffective due to the mismatch of the original shock absorber with new parts. That is, even a deterioration in the behavior of the car is possible.

Therefore, it is recommended to change the rack. This involves the installation of a spring and shock absorber, combined in a one-piece design. Their parameters are calculated by the manufacturer, so these screw suspensions give the best results.

Dignity

The main advantage of such details, due to which theyreplace standard suspensions, consider extensive adjustment possibilities. This allows you to choose the optimal individual settings. Moreover, changing the parameters is very simple for an ordinary user, and for this, improvised tools are enough.

In addition, screw hangers are very easy to install, so this operation can be done by yourself.

Flaws

Suspenders of this type are more difficult to operate than conventional ones. This is primarily due to the need for competent settings to achieve good results. Most of the negative aspects of operation are associated with this, since incorrect adjustment of the parameters can lead to a significant deterioration in the behavior of the car. However, for everyday use, it is enough to adjust the suspension once, and the need for constant adjustment arises only in sports to achieve good results under various conditions. In addition, you can use the services of a specialist to set up or learn it yourself.

In addition, note the vulnerability of the threaded connection, especially to the effects of reagents. To prevent the nut from sticking to the thread, it is enough to use covers for the racks or lubricants.

Application

As is clear from the above, screw suspensions are used to fine-tune the car in order to improve handling. Naturally, this is true for tuning aimed at improving speed characteristics. So, the VAZ screw suspension is very popular, since in stock these cars have a poorhandling, and tuning them is inexpensive, so widespread.

In addition, such parts are used for sports cars to improve their performance to achieve even better results. Therefore, BMW coil suspension is common, especially for older models, as well as for Japanese sports cars.

Cost

The price of the parts in question varies widely depending on the complexity and manufacturer. So, the cost of simple models starts from about 20,000 rubles. These include, for example, the Ta Technix screw suspension. At the same time, the price of the most advanced version of HKS is more than 270,000 rubles.

Installation

Installing a screw suspension is easy with your own hands. It does not require any specialized equipment. A small list of simple tools is enough, including a set of sockets and wrenches of the appropriate diameter, polyhedrons and sprockets, lubricants, two jacks (preferably hydraulic).

It is recommended to read the machine's instructions beforehand to find out the location of the mounting bolts. Moreover, there, most likely, the technology for changing shock absorbers is also indicated.

Begin work on the rear suspension.

• The vehicle must be parked on a level surface.
• Next, remove the wheel, after raising the car.
• Then it along with the spare tireput under the car and lower it.
• Supporting the beam with a jack, unscrew the bolts.
• Shock absorber removed.
• After dismantling both shock absorbers, the beam can be lowered.
• Shock absorber pads should be replaced if worn.
• Before installing new shock absorbers need to be pumped.
• It is also necessary to adjust their stiffness, since the adjustment mechanism will not be accessible after installation.
• Next, top mounts are attached to the new shock absorbers.
• They are bolted to the body.
• Springs are replaced.
• Then the car is jacked up until it hits the shock absorber bolt hole.
• After that, the bolts are tightened and the jacks are removed.

In the process of installation, it is necessary to lubricate the threads and also tighten the locknut.

The technology for replacing the front shock absorbers is the same. Just keep in mind that the bolts are located under the hood.

Settings

You can start adjusting the suspension parameters immediately after installation. This is done with screws.

The number of stats that can be changed varies for different variants. So, in some suspensions, the simultaneous adjustment of ground clearance and spring preload is provided, which allows you to change the height of the car above the road and the stiffness of the suspension. However, it is not possible to set these characteristics separately. The most advanced models have several dozen positionsstiffness, as well as adjusting other parameters such as rebound, compression, camber and castor, with each characteristic being changed separately.

Many coilover suspensions have adjustments for spring preload, camber, ride height, castor.

To adjust the first parameter, if the spring is installed separately, use two nuts (locknut and spring) on the glass or rack.

The ride height is adjusted with two nuts at the bottom of the rack. By loosening the locknut, it is changed without affecting the stiffness of the shock absorbers.

To change the camber and castor, twist the spring cup and bearing.
