Wavetrac Torque Biasing Differential unit 135i, 335i E8x E9x

Designed from experience with the competitions helical gear LSDs, lots of engineering has gone into Wavetrac's differential to ensure its state of the art.

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 135/335 will be a new car when fitted with an LSD: Unlock the speed and poise BMW has reserved for the M3 with one of these LSDs equipped in your ride. 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.
