Whiteline Roll Center / Bump Steer Kit (Ball Joints, Tie Rod Ends) - 2013-2021 Scion FR-S / Subaru BRZ / Toyota 86

KCA435 is designed to raise the front roll-center geometry by using specially engineered ball-joints & tie rod ends while still maintaining original steering geometry in the Scion FR-S and Subaru BRZ. Front roll geometry actually encourages roll the lower you go. Testing proves that raising the front roll-center resulted in a substantial increase to front roll resistance & a significant reduction in suspension compression of the outside front wheel during cornering (less roll). This improves weight distribution & maintains a better camber angle which ultimately improves front grip. The overall outcome is significantly reduced understeer through reduced front wheel compression as well as improved steering precision & vehicle stability.
