Whiteline Roll Center Correction Ball Joints KCA313-BJ | WRX & STI
Video description
Improve your Subaru's suspension geometry with the Whiteline Front Roll Center Adjustment Ball Joints (KCA313-BJ). Designed for lowered WRX and STI applications, these ball joints help correct roll center changes caused by lowering your vehicle, improving handling, steering response, and front-end grip.
When a vehicle is lowered, suspension geometry can be negatively affected, reducing the effectiveness of the factory setup. Whiteline's extended ball joints raise the front roll center, increasing roll resistance and helping maintain better tire contact during cornering.
These ball joints are available as replacement components for the Whiteline Front Roll Center and Bump Steer Correction Kit, making them ideal for refreshing an existing setup or replacing worn components.
