Where traction meets engineering. DiffPro delivers custom differential solutions designed to maximise grip, stability, and confidence in every BMW M car.”
Frequently asked questions
What does DiffPro actually do?
DiffPro specialises in custom-built limited-slip differentials (LSDs) and performance differential upgrades for BMW M vehicles. We rebuild, upgrade, refine, and service differentials to improve traction, handling, and overall drivability for both street and track M-cars.
What warranty do you offer?
All DiffPro differentials come with a 12-month warranty covering workmanship, assembly, and internal components under normal performance use.
Do I need to “break in” the differential?
Yes. For the best lifespan and performance:
- Avoid aggressive launches for the first 500km
- Allow fluid to warm before heavy driving
- We recommend a 500–1000km fluid change after break-in
Which BMW models do you work on?
We service and upgrade differentials for most BMW M models, including the E82 1M, E9X M3, F80/F82 M3/M4, F87 M2, G80/G82 M3/M4, and selected non-M models running M-style diffs. If unsure, contact us and we’ll quickly confirm compatibility.
