Part Number: KCA425M

Description: Anti-Lift/Caster Kit; Control Arm - Lower-Inner/Rear; Sport Bushings

Fitment: 22+ Subaru WRX

Details:

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

This kit replaces the front control arm rear vertically mounted bushing and features a 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 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).

Features: 

• The latest in material formulation technology boasts resistance to oil, grease, ozone and weathering.

• Provides a window of adjustment to rectify or optimize a vehicle's wheel alignment.

• Articulation voids deliver necessary suspension articulation and/or compression under loads.

• Engineered to alter/optimize caster alignment to maximize tire contact patch during roll, improve turn-in response & increase directional stability.

• Featuring anti-geometry that works to aid traction by allowing the wheel to track the ground more precisely resulting in superior traction under power including cornering and dramatically reducing understeer and front wheel spin.

• Featuring premium anodized alloy materials, providing a long-lasting protective barrier to corrosion and wear but they look great too.

• This kit is covered by a 3 Year / 60,000kms warranty including parts and labor.

• Install guide included providing detailed instructions on how to install your new purchase.
