Reduces roll centre - suits JDM alloy arm - 14mm ball joint - essential for lowered vehicles, A must for lowered vehicles, Whiteline roll centre correction kit, is designed to correct roll-centre geometry using specially engineered ball-joints. Raising the front roll-centre results in a substantial increase to front roll resistance and a significant reduction in suspension compression on the outside front tyre during cornering. The result is more even weight distribution and improved tyre contact ultimately improving front end grip, cornering speeds and tyre life when driving the vehicle to it’s potential., 3 Year / 60,000Kms
