Product Description

The Whiteline KCA388 addresses a common side effect of lowering an Evo: bump steer, where road imperfections cause the car to tug off-line without driver input. It works by replacing the factory rear toe/control arm inner bushing with a design that corrects the suspension geometry thrown off by a lower ride height.

By keeping dynamic toe settings more consistent through wheel travel, it sharpens turn-in and cuts down on the constant steering correction that lowered Evos are known for. It's commonly paired with Whiteline's front roll-center kit for a full geometry correction on a lowered setup.
