Whiteline Anti-Lift & Caster Correction Kit - 2011-2026 Subaru WRX / STI

Transform Your Handling: Anti-Lift Technology & Caster Correction
The factory front lower control arm bushings on the Subaru WRX and STI are designed for compliance, which unfortunately allows for significant "lift" under acceleration and "dive" under braking. The Whiteline KCA425 Anti-Lift Kit is engineered to change the geometry of the front suspension. By lowering the rear mounting point of the front control arm, it reduces the front-end lift during hard acceleration, keeping your tires pressed firmly into the pavement for maximum traction.

Superior Steering Feel and High-Speed Stability
Beyond the anti-lift benefits, the KCA425 features an offset design that provides additional static caster. Increasing caster improves your car's "straight-line" tracking and provides a much-needed increase in steering weight and self-centering feel. Built with Whiteline’s signature synthetic elastomer and high-strength alloy, this kit replaces the soft, often fluid-filled factory bushings with a solution that won't deflect under high-G cornering.

• Improved Front End Grip: Maintains a better tire contact patch during aggressive driving.
• Increased Caster: Enhances turn-in response and high-speed directional stability.
• Reduced Understeer: Helps the car "rotate" better through corners by optimizing suspension geometry.
• Durable Synthetic Elastomer: Resistant to chemicals, road salt, and extreme weather; outlasts OEM rubber.
