he Whiteline anti-dive caster kit dramatically improves vehicle stability. In stock form the front end of the BRZ/FR-S 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 and adds .05 degrees of positive caster. You can expect greater traction under power, braking, and cornering with dramatically reduced understeer & front wheel spin. The additional caster coupled with the firmer bushings serves to dramatically sharpen initial turn-in response while forcing more consistent alignment angles through the corner due to the reduced bushing compliance.
Location: Lower inner front bushing
Alignment: Adds 0.5 degrees Positive Caster
