Powerflex Track Rear Diff Rear Mounting Bush - G80 M3 (2020 on) - PFR5-4026BLK

Rear differential mount upgrade for BMW M3 G80 2020 onward

Stiffen the rear driveline and put power down more effectively with this high-performance rear differential mount bushing for the BMW M3 G80. Engineered for hard launches, circuit work and fast-road use, it limits final drive movement so torque reaches the tarmac, helping to curb wheel hop and improve traction out of corners.

Built around a Black Series 95A polyurethane insert and an integrated black anodised 2011-T6 aluminium support washer, this replacement mount delivers a firmer, more controlled rear end feel without compromising on precision. It is a direct replacement for the standard part and is designed to reduce drivetrain deflection under load.

• Performance polyurethane 95A compound helps suppress wheel hop during aggressive starts
• Integrated black anodised 2011-T6 aluminium support washer adds stability under load
• Direct replacement for the factory mount to control driveline movement
• Can be paired with the optional PFR5-4030 dual-mount rear differential bracket to run two bushes in the OE positions for extra support
• Track-focused durability with crisp, predictable rear axle response
