Upgrade the rear suspension on your BMW with the Powerflex Rear Upper Control Arm To Hub Bush, Reference No. 12a, Part Number PFR5-412-12a. This Powerflex Road Series polyurethane bush is a direct replacement for the original rubber bush and is designed for road and fast road use. It reduces unwanted suspension flex, improves handling precision, helps maintain correct alignment under load and delivers a tighter, more predictable rear end feel.
Ideal for enthusiasts looking for a reliable BMW rear suspension upgrade, these performance bushes improve road holding and chassis stability which can lead to prolonged tyre life, increased performance and greater safety. We have fitted these bushes ourselves on customer cars and feedback has been consistently positive, with sharper turn-in and better traction reported across a range of fast road BMW builds.
