Whiteline's 'MOTORSPORT ONLY' Anti Geometry Kit replaces the front control arm rear vertically mounted bushing and features lightweight aluminum housing with high performance/low compliance bearings for optimum dynamic alignment under the high rigors of motorsport applications. Positive static caster gains can also be achieved by the offset orientation of the bearing and all motorsport kits come in 'STEALTH BLACK'. Unique to any Whiteline Anti geometry kit before it, KCA425M allows WRX and STI owners to tune geometry from Anti Lift to Anti Dive via a combination of recommended spacers delivering a window of handling behavior to suit varying track, vehicle set up and driver needs.
