Thanks for all the posts on this thread. Just bought a Spec 3+ and will install it next week. Good to hear most of you are happy with them. It's replacing a Spec 2+ which is just about the worst street clutch I've ever had in any car, ever. And I've owned a lot of em in 40 years of driving. The 2+ is just about worn out with only 25,000 miles on it (NO track use) and the chatter was just awful from day one. Guess it was the puck style disk?
FWIW, I would not be surprised about at least a little chatter from the 3+. The disk is bonded onto flat steel plates, not wave spring plates like the factory clutch.
