Whiteline's 'MOTORSPORT ONLY' Anti Geometry Kit for 2011 Subaru WRX STI (excludes WRX) replaces the front control arm rear vertically mounted bushing and features lightweight aluminium housing with high performance/low compliance bearings for optimum dynamic alignment under the high rigours 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'.
