i've got the rps stage 3 sprung hub 6-puck carbon on my supra. i've heard it's good for around 600 hp, but i'm just about to go over that mark. i'm not very hard on it, hardly any hard launching, and i broke it in for 500 miles. only about 1500 miles on it so far. i'm looking for about 670 rwhp, and it will see only very limited track use. think it will hold it???
