Wavetrac ABT Limited Slip Differential for the BMW F87 M2, F80 M3 and F82 M4 is an industry-leading LSD designed for high-performance road and track use. It features patented technology that prevents loss of drive when the inside wheel becomes unloaded. On bumpy surfaces or aggressive kerb use, an internal Wavetrac device generates load and transfers torque to the wheel with grip, delivering consistent traction where conventional LSDs fall short.

The Wavetrac differential is ideally suited to powerful road cars that also see track time. It is extremely strong yet remains transparent during everyday driving, working seamlessly with factory traction control systems. Under hard driving conditions, it delivers power to both wheels without the understeer or harsh engagement often associated with clutch-type differentials.

Unlike traditional gear-type differentials, the Wavetrac will not lose drive when one axle is unloaded — a scenario that occurs frequently during spirited driving or track use. This results in improved corner exit speed, better stability, and more consistent lap times.

One of the most underrated benefits of the Wavetrac is its exceptionally smooth power delivery at the limit. Its patented design allows predictable and progressive torque transfer when traction is marginal, giving the driver confidence to stay on the throttle through critical moments.

Smooth is fast.
