SKU: W00A KCA313-BJ
Description
Part #: KCA313-BJ
A must for lowered vehicles, Whiteline roll center and bump steer correction kits are designed to correct roll-centre geometry using specially engineered ball-joints and tie rod ends. Raising the front roll-centre 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.
Features:
- Engineered to alter vehicles roll centre, increasing tyre grip to the road, optimising the vehicles steering and handling characteristics.
