Rear Dual-Mount Rear Differential Bracket - PFR5-4030

 

Supplied complete with M14 bolt, thread locker and Powerflex keyring
With the newer F8xM2/M3/M4's making big power and having superb chassis straight from the showroom, it's no wonder they're often found at the most serious of track-days or at tuning shops across the globe. Unfortunately, the power that makes these cars so fun to drive eventually has an impact on the vehicle components, most notably the rear differential bushes. Despite having the provision for two mounting bushes on the factory tubular subframe, BMW opts to use only a single offset bush to mount the diff bracket to the subframe. This essentially creates a pivot point for the diff under torque loading, especially if the 4x front diff bushes are worn and softened. We are proud to release a high-performance solution to this problem, giving you the tools to re-establish rear-end stability on your F8xM2/M3/M4. PFR5-4030 Dual Mount Diff Bracket is made from our in-house CNC machined 6082 High-Tensile Aluminium and is designed to utilise the secondary mounting position on the OE subframe. With the addition of a second bush, this prevents the diff from twisting under load, providing benefits such as:

  • Reduced drivetrain movement
  • Improved throttle response
  • A more controlled and consistent on-off throttle chassis response
  • Improved tyre-to-road power transfer reducing wheel hop
  • Reduced strain on fitted bushes

The corrosion-resistant Satin Black Anodised Aluminium Bracket is optimised for high stress and deflection whilst withstanding high torque loads but is designed to function equally on standard or modified vehicles with either a single OE bush or dual aftermarket bushes.
