Powerflex Front Wishbone Rear Bushes – Aluminium Outer, Eccentric (E46 M3)


The E46 M3’s front control arm bushes are known point of periodic failure, especially with lowered or hard used examples. The ‘aluminium outer’ version of the Powerflex FCAB uses a high quality hard anodised outer shell with a low friction polyurethane inner, available in either standard Powerflex material or harder ‘Black Series’ material, intended for track use. This minimises lower arm deflection, delivering the most consistent geometry possible while offering compliance for road and track comfort.

This version of the bush features an offset bore to add 0.5 degrees of additional caster for increased steering feedback and self-steer. 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.
