The Whiteline anti-dive caster kit for the Subaru STI/WRX/LGT dramatically improves vehicle stability. In stock form the front end of the STI, WRX and Legacy GT has a tendency to move around which equates to less then predictable handling. The front end will lift up when accelerating and dive to the ground when braking aggressively. The anti-dive kit, or commonly referred to as the WALK kit, from Whiteline keeps the front end under control and provides the driver with more predictable handling. This kit reduces deflection and adds 0.5 degrees of caster.
