Powerflex BMW F80 F82 F83 F87 Dual Mount Rear Differential Bracket - PFR5-4030
Upgrade your BMW F8x drivetrain with the Powerflex Dual Mount Rear Differential Bracket PFR5-4030. Designed for the BMW M2, M3 and M4 platforms, this CNC machined 6082 high tensile aluminium bracket utilises the secondary factory mounting position on the OE subframe to transform rear-end stability, reduce drivetrain movement and improve throttle response. Ideal for fast road and track day use, this rear diff mount upgrade is the proven way to reduce wheel hop and keep power delivery consistent on BMW F87 M2, F80 M3 and F82 F83 M4 models.
Why owners choose this BMW rear differential bracket upgrade:
- Dual mount design stops the diff twisting under load by using both subframe mounting points
- Reduced drivetrain movement for sharper, more predictable handling
- Improved throttle response and consistent on-off throttle chassis behaviour
- Better tyre to road power transfer that helps reduce wheel hop
- Less strain on rear differential bushes for improved longevity
- Corrosion resistant satin black anodised aluminium engineered for high torque loads
On the F8x platform the OE subframe has provision for two rear diff mounting bushes, but BMW uses a single offset bush. Under torque this creates a pivot point that allows the differential to rotate, especially as the front diff bushes soften with age. The Powerflex PFR5-4030 dual mount diff bracket solves this by adding the second bush location for a locked-in, motorsport-grade solution that works brilliantly on standard or modified cars.
