Whiteline KCA425 Anti-Geometry Front Control Arm Lower Inner Rear Bushing Kit for Select Subaru 2008-2025

Fits select 2008-2025 Subaru Impreza WRX STI, WRX, Legacy, and Outback models.

The Whiteline KCA425 Anti-Geometry Kit is a precision suspension upgrade designed to replace the front control arm's rear vertically mounted bushing. This kit utilizes high-performance, low-compliance synthetic elastomer bushings and bearings to maintain optimum dynamic alignment during aggressive driving. Unique to this Anti-Geometry kit, the KCA425 allows drivers to tune suspension geometry from Anti-Lift to Anti-Dive configurations using a combination of included spacers, providing a customized handling window for various vehicle setups.

Constructed with premium anodized alloy materials and protective plating, these components are engineered to withstand harsh road conditions and resist corrosion. By optimizing caster alignment and reducing unwanted bump steer, the KCA425 maximizes the tire contact patch during cornering, significantly improving turn-in response and directional stability.
