Factory rubber bushings are intentionally soft and open in design to allow multi-axis movement during steering, but under heavy braking they compress and release, allowing unwanted arm deflection. The result is reduced stability, inconsistent braking feel, and tire skip—issues that are amplified when ABS is engaged or the car is driven hard. Whiteline’s upgraded arm and bushing solution dramatically reduces this compliance, keeping the suspension geometry stable and the tire planted under load.
