By the cost down of normal front lower arm by Suzuki Motor Co, the arm is made with one piece mold steel plate and the intensity is insufficient so the suspension arm does not work a normal performance specially when you lower the height of car.

With our reinforced lower Arms, you can enjoy the driving by ordinary performance of suspension at corner and better response of steeling. We strongly recommend this set for your car.

Theory of Roll Center

In normal condition :
The roll center is a center line when a car rolls and is upper part of body center line which is crossing an extension line of upper arm and bottom arm for suspension and center part of tire. Normally the roll center should be lower part of body gravity. The volume of basic roll will be decided by the length between its gravity and roll center.

When body height lower :
The gravity of body is also lower so the roll center is also lower than normal position. So when a body height is lower than normal height, the volume of rolls will be larger. The spring rate of suspension will be usually upper when body height will be lower, but this occurs the suspension performance lower.

Adjusting roll center :
To change the position of lower arm of suspension, the position of roll center will be higher and enable to be a best position of roll center. The performance of suspension will be showed as an essential performance.
