Powerflex PFR5-1226 Rear Final Drive Rear Mount Bush for BMW E82 1M and E9X M3

Lock in rear axle control and feel the difference every time you turn the wheel. This Powerflex PFR5-1226 rear final drive rear mount bush replaces the tired OE rubber item to curb excessive differential movement, tighten the rear end and deliver crisp, confidence-inspiring handling on the road and fast-road setups. It is a direct-fit upgrade for the factory part referenced by OE number 33312283384.

Built in Powerflex Road Series polyurethane, this mount resists distortion far better than standard rubber while keeping refinement suitable for daily use. We run this exact bush on our own cars and customer builds and the feedback is consistently excellent: more composed cornering, improved traction over B-roads and a planted, predictable rear end.

Why this rear final drive mount is a must-have

• Controls differential movement for sharper, more stable handling
• Improves rear axle composure under acceleration, cornering and braking
• Helps deliver consistent alignment and tyre contact for better grip and tyre life
• Durable polyurethane construction offers long-term performance versus ageing rubber
• Direct replacement fitment with no guesswork
