Powerflex Dual-Mount Rear Differential Bracket for BMW F87 M2 - Part Number PFR5-4030

Upgrade the rear diff mount on your BMW F87 M2 with the Powerflex Dual-Mount Rear Differential Bracket PFR5-4030. This essential rear differential upgrade is engineered for the F8x platform and is a proven solution for stability, strength and traction on fast road and track. Ideal for BMW M2 owners looking to reduce drivetrain movement, improve throttle response and cut down wheel hop and clunk from the rear end.

BMW fitted the F8x subframe with two rear diff bush locations but only used a single offset OE rubber bush from factory, which creates a pivot point under torque. Hard launches and repeated on-off throttle inputs can twist the differential, accelerating bush wear and causing instability and noise. Powerflex PFR5-4030 utilises the secondary mounting position to create a true dual-mount rear diff bracket that locks the differential down and restores confidence.

Key benefits

  • Reduces drivetrain movement for a more planted rear end
  • Sharper, more consistent throttle response
  • Improved tyre-to-road power transfer and reduced wheel hop
  • More stable on-off throttle chassis behaviour
  • Less strain on rear diff bushes and surrounding components

Built to perform

  • CNC machined 6082 high-tensile aluminium bracket
  • Satin black anodised for corrosion resistance and durability
  • Optimised for high stress and deflection to handle high torque loads
  • Works on standard or modified vehicles with either a single OE bush or dual aftermarket bushes

What you get

  • Powerflex Dual-Mount Rear Differential Bracket PFR5-4030
  • M14 bolt and thread locker
  • Powerflex keyring

Recommended complementary bushes

  • PFR5-4026 Rear Diff Mounting Bush - fit in both rear subframe positions for a true dual-mount setup
  • PFR5-4025 Rear Diff Front Mounting Bushes - complete the package for ultimate differential control

Fitment and use
