Whiteline Front Roll-Center/Bump-Steer Correction Kit for Select 1993-2021 Subaru & Saab (KCA313-TR)

Fits select 1993-2021 Subaru Impreza, WRX, STI, Forester, Legacy, Outback, XV Crosstrek, and 2005-2006 Saab 9-2X.

Essential for lowered vehicles, the Whiteline Roll-Center and Bump-Steer Correction Kit is engineered to restore suspension geometry after ride height adjustments. When a vehicle is lowered, the angle of the front control arms often shifts, moving the roll center further away from the center of gravity and increasing body roll. This kit uses specially engineered ball joints and tie rod ends to raise the front roll center, significantly increasing front roll resistance and reducing suspension compression on the outside wheel during high-load cornering.

By correcting the geometry, this kit improves weight distribution across the tire contact patch, enhancing front-end grip and steering precision. The included tie rod ends also help mitigate bump steer—unwanted toe changes that occur as the suspension moves through its travel—ensuring predictable handling on both the street and the track.

• Replaces worn OE ball joints and tie rod ends with geometry-corrected components
