# Whiteline 11+ Subaru STi Front Race anti-dive caster kit

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'. Unique to any Whiteline Anti geometry kit before it, KCA425M allows STI owners to tune geometry from Anti Lift to Anti Dive via a combination of recommended spacers delivering a window of handling behaviour to suit varying track, vehicle set up and driver needs.

-   Featuring premium anodized alloy materials, Whiteline alloy products are anodized providing a long-lasting protective barrier to corrosion and wear but they look great too.
-   Engineered to alter/ optimise caster alignment to maximize tyre contact patch during roll, improve turn-in response & increase directional stability.
