I had a 6 puck JGY disc that had the springs come out of the disc. Then I was tight on money so I picked up a F1 Stage 3 clutch on here. That one lasted for about 1000 to 2000 miles before the springs came out of that disc. I was looking at picking up a ACT 6 puck, but not sure about that now. For now I might just get the double sprung B15 disc that GSpec carries.
