Whiteline Roll Center Adjuster and Bump Steer Kit for 2013-2026 Subaru BRZ, Scion FR-S, Toyota 86 & GR86 (KCA435)

Fits 2013-2026 Subaru BRZ, Scion FR-S, Toyota 86, and Toyota GR86.

An essential upgrade for lowered vehicles, the Whiteline Roll Center and Bump Steer Correction Kit (KCA435) is engineered to restore suspension geometry after a reduction in ride height. By utilizing specially designed ball joints and tie rod ends, this kit raises the front roll center to increase front roll resistance and reduce suspension compression on the outside front wheel during high-load cornering.

The corrected geometry ensures more even weight distribution and an optimized tire contact patch, resulting in increased front-end grip and higher cornering speeds. Additionally, the kit is designed to optimize toe alignment, reducing inherent understeer/oversteer and preventing uneven tire wear caused by geometry shifts.

• Roll Center Correction: Restores factory roll center geometry on lowered vehicles to improve handling and steering response.
• Bump Steer Reduction: Optimizes toe alignment to eliminate unpredictable steering behavior and minimize tire scrub.
• Corrosion Resistance: Protective E-Coat finish provides a durable skin that resists harsh environmental conditions and corrosion better than conventional paint.
• Heavy-Duty Hardware: Includes specially engineered ball joints and tie rod ends for long-term reliability in performance applications.
• MPN: KCA435

Includes a detailed installation guide to assist with the setup of your new Whiteline suspension components.
