I just bought a spec stage 3 used. the flywheel and pressure plate have been resurfaced. I was wondering it there were certain specs for the disc that I could measure and see how much life is left on the clutch. any ideas
also the pp on the clutch is painted yellow instead of the usual blue has anyone seen this

If you don't mind how much did you pay for it, I'm selling my spec 3 with 4K on it , is why I ask. PM me if you don't want to put it up on here. Thanks.
