thats a good 20k miles more than both my act street and act 6 puck lasted, COMBINED! I'm sorry but ACT overates their clutches. Right now I have the RPS Max sprung disk and its holding the HP on my car just fine (HKS turbos etc, etc,...everything except motor work). So far the RPS works just fine but we'll see when the car goes to the track in a few weeks. Hopefully it WILL run some high 10s. IF NOT I'M SELLING THE DAMN CAR!!! lol j/k We'll see what happens. I'll keep yall posted.
