The E46 M3’s front control arm bushes are known point of periodic failure, especially with lowered or hard used examples. Powerflex developed this polyurethane replacement, available in either standard Powerflex material or harder ‘Black Series’ material, intended for track use. This minimises lower arm deflection, delivering more consistent geometry while offering compliance for road and track comfort.

Please select material when ordering – this bush is for the larger M3 front assembly only.

Size: 60mm. Part number 1 on diagram. Priced per pair – one pair required per vehicle. Covered under Powerflex’s lifetime warranty.
