The E46’s rear subframe bushes are a known point for excessive deflection and periodic failure – they also attribute to the infamous boot floor failure experienced on high power models. Powerflex developed this polyurethane replacement, available in either standard Powerflex material or harder ‘Black Series’ material, intended for track use. This minimises subframe deflection, delivering the most consistent geometry possible while offering compliance for road and track comfort.

Part number 10 on diagrams. Priced per pair – one pair required per vehicle. Combine with Powerflex Rear Subframe Rear Bushes for complete set (recommended). Covered under Powerflex’s lifetime warranty.
