Powerflex Rear Beam Bushes (E30 inc M3)


The E30’s rear beam bushes are a known point for excessive deflection and periodic failure. Powerflex developed this polyurethane replacement, available in either standard Powerflex material or harder ‘Black Series’ material, intended for track use. This minimises beam deflection, delivering more consistent geometry while offering compliance for road and track comfort.

Part number 4 on diagram. Priced per pair – one pair required per vehicle. Covered under Powerflex’s lifetime warranty.
