Whiteline KCA425M Motorsport Front Anti-Dive/Caster Kit for Select 2008-2025 Subaru Impreza, WRX, STI, Legacy, and Outback

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

The Whiteline Motorsport Anti Geometry Kit (KCA425M) is a track-ready solution designed to optimize front-end suspension geometry under high-performance driving conditions. It replaces the factory front control arm rear vertically mounted bushing with a low-compliance bearing housed in lightweight, high-strength aluminum. Finished in "Stealth Black" anodized coating, this kit provides a durable, corrosion-resistant barrier suitable for the rigors of motorsport.

Unlike standard kits, the KCA425M allows drivers to tune the vehicle's geometry between Anti-Lift and Anti-Dive settings using a series of included spacers. The offset orientation of the bearing also increases positive static caster, maximizing the tire contact patch during cornering and significantly improving turn-in response and directional stability. This kit effectively eliminates unwanted bump steer and provides the dynamic alignment retention required for competitive use.

• Adjustable geometry settings: Tune between Anti-Lift and Anti-Dive via included spacers.
• Increased static caster: Offset bearing design improves turn-in and stability.
