E-mail this product to a friend

Roll Center Kit incorporates 2 x steering arm tie rod ends and 2 x ball joints and is designed to raise front roll-centre geometry after lowering the vehicle with Control springs and also improve on the original bump-steer geometry. Changing front suspension geometry by raising roll-centre, results in substantial increase to roll resistance and significant reduction of suspension compression of outside front wheel during cornering through improved weight transfer distribution. Whilst bump steer correction via extended tie rods aids in minimising steering angle input during suspension articulation.

This kit is designed to raise the front rollcentre geometry by using specially engineered ball-joints and tie rod ends while still maintaining original steering geometry. The front roll geometry actually encourages roll the lower you go. Tests showed that raising the front rollcentre 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, maintains a better camber angle, and ultimately improves front grip. The overall outcome is significnatly reduced understeer through reduced front wheel compression, as well as improved steering feel, steering precision, and vehicle stability.

Kit is supplied with 2x complete sets of specially modified ball-joints, steering tie rod ends,grease cups, mounting hardware, comprehensive fitting instructions.
