when drag racing. Like Citation mentioned, at the strip the stock lsd sends more power to the Right wheel when its cold, and when it warms up it goes stupid. Im planing to buy the Quaife ATB LSD, why? well because its Gear type instead of Clutch type, that means it wont chatter and no maintanace, also, with the quaife your using equal lenght output shafts. So your not transmiting/putting more stress on the longer output shaft which is the passanger side. Hope that helped.
