A high roll center reduces the tendency for the chassis to roll and thus lessens the need for camber gain.There are other issues related to high vs.Low roll centers and control arm linkage design to lessen camber loss on chassis roll, and these can introduce new factors affecting handling.

A lowered rear roll center promotes side bite at the rear which tends to tighten corner handling.However, an extremely low roll center can generate excessive chassis roll which can cause suspension geometry problems.Also, excessive roll can delay corner exit acceleration Raising the panhard bar raises the rear roll center.

Roll Center Explained

Camber is the angle at which the wheel and tire stand relative to the road – assuming it is perfectly flat.The easiest way to envision what camber looks like is to view the wheel and tire head on.When stationary, the tire maintains a static camber angle, whereas when the car is cornering, due to body roll, the contact patch is reduced.
