Installation Notes

Professional installation is highly recommended on all final drive and pinion kits.

highly recommended hardware

Chassis specific differential refresh kits.

After upgrading final drive gears and pinions in my M cars, I have compiled the required hardware to refresh your original BMW M-Variable.

The refresh kits are the same no matter which gear ratio you choose, and which transmission you run.
