The Whiteline anti-dive caster kit for the 08-10 Subaru WRX/STI dramatically improves vehicle stability. In stock form the front end of the WRX 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. Whiteline offers two different versions of the anti-dive kit to fit different types of driving demands. The "Race" version incorporates a metal bearing for the least amount of deflection as possible and adds 1/3 of a degree of caster. The "Race" version is not recommended for street use due to the increased noise and harshness. Includes all necessary hardware and installation instructions.
