Wavetrac ABT Limited Slip Differential for a wide range of E Series & F Series BMW models. This Wavetrac LSD features patented technology that prevents loss of drive when your vehicle's inside wheel becomes unloaded. This means that on bumpy surfaces or racetrack curbs, load is generated by a device inside the Wavetrac differential that is then transferred to the gripping wheel. With most LSD's you will not see this benefit and the results will show in your lap times.
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.
