Quaife or other LSD is great regardless of which version you have.

It's just horrible. Cuts power more or less consistently when driving hard in the first three gears, on a track the car feels as if it hicupped continuously. I can't imagine who would really want this if you have the choice of getting a real torsen-diff. It may not be bad for the daily granny driver, but once you start adding power to your car or driving it a bit harder, you'll find it quite annoying. That is in fact THE reason why a Quaife is no. 1 on my wishlist right now.
