toque rating is what important and that what kills a clutch.
The rating stated is handling rating at fly so on average R build that clutch around the 380 to 430 hp and probably bit over if not thrashing it to the max . 4wd and R's potential rapid power delivery works the clutches hard so always good match with bit of power handling reserve (CC ratings are based on 2wd sr20 applications) and use sprung friction plates unless specifically built box for aggressive solid plate usage or you happy handle potential problems on more standard boxes .
Need take time research and buy wise clutch package for usage even if means mixing lighter sprung covers with paddle plates to give desired durability but sensible pedal load .
CC clutches are pretty good but be careful of the heavy sprung ones, quite lot of info on CC from few users on here in various clutch threads .
