KCA313 is designed to raise the front roll-center geometry by using specially engineered ball-joints and tie rod ends while still maintaining original steering geometry. 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 and a significant reduction in suspension compression of the outside front wheel during cornering (less roll). This improves weight distribution and 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 and vehicle stability.
