Powerflex Rear Bar Mount Bush Set 13 mm for BMW 3 Series F30 F31 F34

This 13 mm polyurethane rear bar mounting kit from Powerflex replaces tired factory rubber with performance-focused bushes that deliver cleaner response, flatter cornering and greater confidence on B-roads, commuting and fast-road driving. Expect sharper turn-in, improved stability mid-corner and more consistent grip when you lean on the car.

Why this upgrade works

Factory rubber softens and deforms over time, allowing unwanted movement that blunts feedback and increases body roll. Powerflex polyurethane keeps the rear roll bar working exactly as intended, maintaining geometry under load so your BMW drives with precision. The result is a more connected feel without the mushiness that comes from worn mounts.
