Product Details

A must for lowered vehicles, Whiteline Roll Center and Bump Steer Correction Kits on your 2015-2021 Subaru WRX STI (VA) are designed to correct roll-center geometry using specially engineered ball-joints and tie rod ends. Raising the front roll-center results in a substantial increase to front roll resistance and a significant reduction in suspension compression of the outside front wheel during cornering. The result is more even weight distribution and improved tire contact ultimately improving front end grip and cornering speeds.
