the car made 601 rwhp so something that is rated over that would be nice to be safe. it had the centerforce DFX 2 in it and it also has the upgraded input shaft its mostly a street car but it really sees quite a bit of track time. i was thinking spec i know people say its too stiff but they have outstanding clutches. the centerforce was decent but not the best clutch under the stress. i just saw spec offers the upgraded spline hub clutch for no additional cost. if i go spec i think id like the stage 2+. what u guys think? i shouldnt need a new flywheel should i?

p.s the flywheel is not worn down and can be re surfaced
