Wavetrac ATB Differential – BMW M3

The beauty of the Wavetrac is that it is ideally suited to high performance road cars that see track use. It is very strong, yet transparent to both driver and traction control electronics during regular driving. On the track or in spirited road use, it provides drive to both wheels without the handling issues that traditional clutch type diffs create (there is no tendency to push/understeer with a Wavetrac).

The Wavetrac outperforms other gear type differentials because unlike them, it won’t lose drive when one axle is unloaded (which happens more often than you’d think).

Lastly, one of the most underrated benefits of the Wavetrac is its smooth delivery of power near the limit. Its patented design makes for a very predictable, smooth addition of power when you need it most – when things are at their limits: on the edge of traction mid-corner and using throttle to keep it there; or coming into a corner a little hot, but quickly back on it to maintain exit speed…

These situations are often subjective to the driver, but the benefit can be felt. The Wavetrac makes you faster because it lets you drive with confidence. Smooth is fast.

Notes:

The factory ring gear is welded to the crownwheel. To install, the factory ring gear must be machined away from the factory differential. Specialist engineering skills and equipment is required to do this. We can provide this service for you at an additional cost.
An ARP bolt kit is required to install this differential to the factory ring gear, once it is separated from the factory differential and threaded. This is available at an additional cost.
The factory E-LSD must be deactivated in the software of the vehicle. This required specialist equipment to do so and can be carried out by a specialist with the correct systems.
