Whiteline Roll Center kits are designed to correct roll-center geometry using specially engineered ball-joints. The KCA439 kit has 3 adjustment settings to provide precision geometry tuning to the varying heights of lowered Mustangs. Raising the front roll-center 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.

• Protective plating on all metal components acts as a hard skin that is much tougher than conventional paint allowing this product to withstand the toughest conditions and resist corrosion for years to come.
• Engineered to alter/ optimise toe alignment to rectify tyre wear and/or reduce inherent understeer/oversteer behaviour.
