Whiteline has just released an Anti-Dive Caster Kit for the 2011 Subaru WRX STI (excludes WRX). This kit replaces the front control arm rear vertically mounted bushing and feature light weight 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 behavior to suit varying track, vehicle set up and driver needs.
