Wavetrac Helical LSD (BMW E39/Z8/E9X)

Wavetrac uses a patent pending design to offer the advantages of a gear based torque biasing differential with improved grip in low traction/no load conditions.

Wavetrac gives you quicker acceleration and faster cornering by driving both drive wheels instead of just one when (even when one wheel unloads or nearly unloads). It offers the best no-load performance when compared to all other helical gear differentials on the market. This means its performance is assured even in bad weather like rain or snow, or beautiful weather under ideal conditions.

Your E39 (all V8 models) / Z8 will be a new car when fitted with an LSD or upgraded to this LSD: Your larger BMW will have grip and control at the limit beyond what you thought was possible. Whether you are just a street enthusiast, a track junkie, or even drag racing, this LSD will power your BMW with a new confidence and control you have never experienced.
