Whiteline KCA425 Anti-Geometry Control Arm Lower Inner Rear Bushing Kit

The Whiteline KCA425 Anti-Geometry Kit is a high-performance suspension upgrade designed to replace the front control arm rear vertically mounted bushing on Subaru WRX and STI models. This advanced bushing kit features low-compliance synthetic elastomer construction combined with precision bearings to deliver optimum dynamic alignment and sharper handling response.

Key Features:

• Replaces factory front control arm rear bushing with high-performance bearing design
• Low-compliance synthetic elastomer material reduces unwanted deflection
• Provides positive static caster gains through offset bearing orientation
• Adjustable anti-geometry tuning from Anti-Lift to Anti-Dive configuration
• Includes recommended spacers for customizable handling characteristics
• Reduces wheel movement under braking and acceleration for improved stability
• Enhances steering precision and cornering responsiveness

This unique kit allows WRX and STI owners to fine-tune their vehicle's geometry to match their driving style and needs. By adjusting the spacer configuration, drivers can optimize handling behavior for street performance, track use, or spirited driving. The precision bearing design maintains proper alignment under load while minimizing compliance that can lead to imprecise steering and poor handling.
