Upgrade the rear end of your BMW M3 F80 with the Powerflex PFR5-4026 polyurethane rear differential rear mount bush. This uprated performance bushing replaces tired factory rubber to tighten up the driveline, sharpen response and deliver repeatable handling under hard acceleration and cornering. It is the go-to final drive rear mount solution for fast road and track-day M3 owners who want precision without harshness.

What you will feel

• Crisper throttle-on behaviour with reduced differential movement and improved traction on exit
• More planted rear axle stability that helps tyres maintain better contact with the road
• Consistent geometry under load for confident braking and predictable turn-in
• Polyurethane formulation engineered to control NVH at a level comparable to quality rubber
• Built-in support washer to reinforce the final drive under acceleration for added durability

Why choose Powerflex for your F80 M3

• Performance-focused polyurethane that resists deformation where standard bushes compress and age
• Excellent longevity that helps protect tyres and suspension components over time
• Backed by the renowned Powerflex Lifetime Warranty
