I am currently putting down 500rwhp with the stock clutch and have 28000 miles. I am not to sure how long the stock clutch will hold up. I have plans to upgrade the supercharger and putting down 600 rwhp. What clutch should I go with that the ability/durabilty to handle 600rwhp and still feel street friendly but can handle well at the track. I heard talk about Spec 3+ or 3 and Centerforce Dual Friction are these any good. Any expert advise would help. Thank You.
