I had a 6 puck fail on me in just 8 months of use. Your best bet is to contact ACT. They only have a 30 day warranty on the clutches but maybe they can help you out. I spoke to one guy there, he asked me to send pics of my clutch, but I never heard back from them. Good luck.
By the way, I see in your sig you're making over 300tq, if that's the case, that street disc wouldn't stand a chance, its only rated for 240tq.
