Wavetrac are the only gear diff on the market that does not lose all drive when one axle is unloaded. Axles become unloaded in aggressive driving, track cornering, extremely slick surfaces, etc. It happens more than most people realise.

An example to explain how this work is that when you have a conventional gear diff, you're on a race track for a track day and during cornering your inside wheel bumps over the curbing. This is normal for track driving. The issue is that for the brief moments your inside tire becomes unloaded when bouncing over curbs, your other wheel is not getting drive / is not putting power down. Gear diffs need load on both axles in order to function. The result on a track (or during aggressive driving) is that there are many times when a normal gear diff supplies only intermittent power to the gripping wheel.

The difference with the Wavetrac is the patented cam device in the Wavetrac diff prevents loss of drive when that inside wheel is unloaded. The device is able to generate a load inside the diff (to replace the lost load as it happens) that can then be biased to the gripping wheel - in the end making more consistent power delivery through a corner. That makes the car more predictable, and faster overall.
