Product Description

The Whiteline KCA359 Anti-Lift/Caster Offset Control Arm Bushing Kit is designed to optimize front end suspension geometry on select 2000-2007 Subaru Impreza, WRX, WRX STI, and compatible Saab 9-2X models. By replacing the lower inner rear control arm bushings with offset mounts and low-compliance synthetic elastomer bushes, this performance-oriented kit adds approximately **+0.5° static positive caster** while reducing unwanted front lift under acceleration. The result is improved tyre contact, sharper turn-in response, and enhanced cornering stability - especially under power.

Constructed with durable alloy housings and precision spacers, the KCA359 kit maintains tighter alignment tolerances under load compared to stock rubber bushings. Internal grease reservoirs support self-lubrication for smoother operation, and the included hardware makes for a complete installation when used with the proper pressing tools. Ideal for enthusiasts seeking better traction, reduced understeer, and more predictable handling dynamics, this anti-lift kit is a direct replacement upgrade tailored for Subaru GD-series platforms and similar AWD performance vehicles.
