Whiteline whlKTA285 Front Control Arm

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. Whiteline Radius Arm Lower - Arm

• Protective powder coating 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.

The Whiteline whlKTA285 Front Control Arm is designed to reduce suspension compliance caused by soft, open factory rubber bushings. By helping limit arm deflection under heavy braking, this upgraded arm and bushing solution helps maintain stable suspension geometry, improve braking consistency, and keep the tire planted under load.

Factory bushing movement can contribute to reduced stability, inconsistent braking feel, and tire skip, particularly when ABS is engaged or the vehicle is driven hard. The arm features a protective powder-coated finish that provides a durable outer surface and resistance to corrosion. Fitment includes select BMW M2, M3, and M4 applications from 2015 through 2018 as listed below.
