Why do the ACT discs lose springs anyway? If they fixed the "issue", what did they change? Is there a serial number range that identifies the vulnerable discs? What other sprung disc, compatible with the 2600 plate never loses them?
I put this in a couple years ago. Maybe 10K +/- since then. Everything was new - flywheel, TRE trans, ACT 2600 with street disc. No big power (maybe 240), launched every once in a while. Started having trouble disengaging the clutch. Read about the ACT disc throwing springs, and symptoms were similar. So it sat for a few months until tonight when I got the trans out. The tab holding the spring in has broken off.
