Front Control Arm - Lower Inner Rear Bushing Kit

DETAILS

FRONT CONTROL ARM - LOWER INNER REAR BUSHING KIT

Whiteline's 'MOTORSPORT ONLY' Anti Geometry Kit 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 WRX and 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.

Here, you are looking at Whiteline‘s Anti-Geometry Kit for your 2011-2021 STI, or 2015-2022 WRX. 

This kit is specifically designed for Motorsport use, and should not be run on a street-driven vehicle.

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 setup, and driver needs. Use KCA334M for 2011-2014 WRX and non-turbo models.

With a Whiteline Anti Geometry kit fitted to your Subaru, more compliant suspension will be induced during braking and accelerating. This will benefit traction, as the wheel will be able to track the tarmac more precisely. In terms of balance, the front end will have a proportionally lower roll resistance during traction or braking. Aids in reducing the power understeer effect that is present in these vehicles and resulting in a better handling vehicle. Anti dive helps manage weight transfer under braking, resulting in a more balanced chassis at high speed/ lateral loads. With added caster gains resulting in a sharper, more precise steering feel.

“Anti” features in suspension systems are a characteristic that can be used to influence the stiffness of the front or rear suspension under traction forces(under braking or accelerating). The individual terms are relatively straightforward and self-explanatory with the “anti” reducing or totally restricting the characteristic (lifting or diving). In the front suspension, there may be levels of anti-dive during braking and anti-lift during accelerating (assuming traction to the front wheels is present).
