There are many threads about Quaife vs Wavetrac. After reading some of them, and examining the information about each, I decided on the Wavetrac. I chose it because:

1. It's slightly cheaper.
2. It is essentially the same exact type of differential as the quaife, except it transfers power even when one wheel does not have any traction at all. This seems to not be anything significant, but I track my car, and in a big sweeping corner, the outside tire has no traction at all. Theoretically, the quaife is useless in this scenario.

This is just my personal opinion. It boils down to how you are using your vehicle. If you don't track your car at all, then IMHO, you don't even need an LSD.
