The E46 M3’s front anti-roll bar bushes are known point of periodic failure, especially with lowered or hard used examples. Powerflex’s polyurethane replacements are available in either standard Powerflex material or harder ‘Black Series’ material, intended for track use. This minimises anti-roll bar deflection, delivering the most consistent geometry possible while offering compliance for road and track comfort. Please check your anti-roll bar size to select the correct option from the drop-down menu.

Part number 2 on diagram. Priced per pair – one pair required per vehicle. Covered under Powerflex’s lifetime warranty.
