How do the large upgrade units (Whiteline, Perrin, & GT Spec) work?
Layman’s Explanation They relocate the transverse link mount by varying degrees (depending on manufacturer specs) changing the car’s OEM suspension alignment by adding additional positive caster. To imagine the physical working of this technical change, please consider the following analogy: Imagine you are arm wrestling someone using a straight arm. You have an equal chance of winning if you keep a straight arm. Now imagine you are arm wrestling someone with their hand bent at the wrist. This transmits your straight arm force from one direction to two directions, straight down and a sweeping motion towards the table. This is the exact way the large upgrade units work. When braking or accelerating, they change the suspension angle so that some of the force is diverted not through the springs, but through the car’s inherent chassis stiffness. This diversion amounts to an increased amount of the front end lift during acceleration and increased amount of front end dive during braking. The
