MMX Rear Final Drive Twin-Point Support Bracket for BMW G80 G81 G82 G83 G87

Unlock sharper power delivery and rock-solid rear axle control with this MMX twin-point support for the rear final drive. Engineered to use the factory secondary locating position on the casing, this reinforcement adds a second attachment point that dramatically limits unwanted movement under load. The result is a crisper driveline feel when accelerating, cornering and shifting, with more consistent traction and confidence on road and track.

Why enthusiasts choose this upgrade

  • Firmly locates the rear final drive during hard launches and spirited driving
  • Helps curb axle tramp and wheel hop for cleaner getaways
  • Improves torque transfer to the tyres for stronger grip and stability
  • Reduces slack in the driveline for a more connected throttle response
  • Utilises the unused secondary fixing point for added rigidity without fuss

We have fitted this on multiple customer cars at MJ Modifications and the feedback has been fantastic. Drivers report more consistent launches, tighter rear-end behaviour and a noticeable boost in confidence when pushing on. It is a simple, high-impact driveline upgrade that pairs perfectly with power and suspension tuning.
