The BMW E36’s differential mounting 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 differential movement, resulting in more consistent power delivery and response while offering compliance for road and track comfort.
Part number 25 on diagram. M3 Evo bushing unique to model, please select in options if required. Priced per bush – one required per vehicle. Combine with POWERFLEX Differential Rear Mounting Bushes for complete set (recommended). Covered under POWERFLEX’s lifetime warranty.
