Sometimes only one wheel is spinning, but sometimes both wheels are. I guess that the problem is still the same - the diff is worn out. BTW, what kind of oil should be in the stock diff?

But for the same reason a torston diff is harder to drift, its harder to brake traction and once traction is broken suddenly the torque converter has no torque left to convert and you immediately loose all power to the wheels, it's like putting the car in neutral in the middle of a drift (all in my lamemans terms offcourse, but this is how my simpleton brain interprets what I've read about them).

I think it's not so bad with the Torsen. The problem with Torsen is that if one of the wheels looses traction completely the torque will not be transfered to the other wheel and the effect is the same as with the open diff. However I believe that on tarmac surface even if one wheel is spinning there is still some torque put to the ground through that wheel. As a result the torque is still being transfered to the second wheel. If the wheel is lifted from ground completely then you have an open diff.

Torsen is supposed to be the best diff for road racing, because the lockup is not as sharp as for clutch LSD and thus you can drive closer to the limit in the corners. For drifting you actually want this sudden lockup to break the traction and so the clutch LSD is better.
