Yes but if you have enough power to make the inner wheels spin and loose traction during a turn, then an LSD would be benificial now wouldn't it?
Open diffs suck, they are no fun at all.
yes, LSD==positraction. I prefer to say LSD since positraction is a ford\chevy term.

Viscus LSD's are awful for preformance (as you can see, there is no SOLID connection, same thing that makes automatic transmissions suck [the torque converter]). Quaife sucks for racing since once one wheel reaches zero traction, the torque bias suddenly becomse 100% to that wheel, basically an overly complex open diff. Clutchpacks are great for racing & preformance and there is no loss of power from the clutches. Nascar uses a detroit locker diff that locks the rear axles together completely under load, Great for foreward traction, but suck for turns, not really important to them is it? :P
