Ideal for suspension refreshes, MOT repairs, or performance handling restoration.

This control arm maintains precise suspension geometry and keeps the wheel correctly aligned under all driving conditions. It absorbs vibration and road shock through its integrated bushings, helping to deliver smooth ride quality and sharp steering response. By keeping the wheel carrier securely located, it ensures predictable braking, stable cornering, and the refined handling expected from a Porsche. Replacing the arm restores proper suspension behaviour when the original bushings or joints have worn out.

Over time, the control arm and its bushings can wear, crack, or develop excessive play, which negatively affects steering accuracy and suspension stability. This can lead to clunking noises, wandering steering, uneven tyre wear, and reduced confidence during high-speed driving. Installing a new OE-match arm restores tight, precise handling and ensures the car remains safe, stable, and compliant with factory performance standards.
