Learning How to Modify a Cars Suspension System


A car’s suspension system is complex; its parts are inextricably linked. Regardless of the shape and size of the car, only 4 wheels touch the ground and support the car’s weight, as well as the people and things it carries.

Dynamic inertia will cause weight to be transferred to the vehicle, whether it is accelerating, decelerating, or turning, resulting in a rapid increase in stress on some individual tires. For example, if an emergency brake is on the ground, the weight initially supported by the rear wheels will be instantly transferred to the front wheels. The two previous tires, which could withstand only 600 kg, will now withstand perhaps more than 800 kg.

If the driver applies the brake quickly, more weight will be transferred to the front end. Also, if the car makes a sharp right turn at high speed when the driver suddenly loses gas, the weight load on the right rear wheel will be zero because the car is now in the air. Now, the weight load on the left front wheel will reach 800 kg, and on the left rear and right front wheels – 80 and 120 kg, respectively. The severe imbalance phenomenon can cause the left front wheel to slip due to heavy load, resulting in loss of control.

As a result, the left rear level does not have enough downward force due to the low weight load, so there is not enough frictional force to cope with the left side force generated by the right turn, thus creating a left traverse. The above example simplifies, but the basic principle is clear. If you could reduce the weight transfer while driving, the slip limit could be increased, significantly improving overall handling. And now, you would like to present several methods for reducing weight transfer.

The first way is to reduce the weight of the car. As the total weight becomes less, the carry weight decreases. The weight load on tires under the same conditions is lower, so the limit will increase. Remember to reduce the useless things in the car, especially the trunk, as they will follow the car’s dynamic inertia in gear, affecting stability. Read more at https://www.pedders.com.au/.

Lower the car’s center of gravity because the lower the center of gravity, the less the car rolls, which means less weight is transferred. Lowering a car’s center of gravity is the easiest way to lower its height. But do not cut the original springs to achieve your goal, as this may cause some side effects.


Increase the car’s anti-roll ability, which requires strengthening the body and suspension system to suppress the amplitude of the car’s roll. The most common form of modification of this type is the installation of reinforced springs and shock absorbers, equipping the car with front and rear struts and anti-roll bars.
