ACT USA, I measured the puck thickness to be less than 0.10 of a mm different from new, and there was no glazing on the flywheel so it was in decent condition, this is a picture on the day I received it:
As a review of how it felt to drive this clutch in my car, it has a very On/Off button feel, the ceramic tends to screech and whine when its cold, and it's not a very comfortable clutch for city traffic. How-ever, the lightness of the setup did make for a very notable improvement in engine response. The revs would rise and fall much much quicker than the oem set up. This clutch handled a few launches under my foot, with a little light feathering into a 4wd launch it hooks up very well and never slipped on me.

I am happy with the use I got out of the ACT clutch kit, it sufficed for one season and put up with everything I threw at it. I guess the extra power and torque that the new tune has produced was just too much for it to handle, and it was probably close to the end of it's life anyways.
This story has been transmitted to Advance Clutch USA, and we'll be posting their response up here when it is available, I'm interested to see their take on this.
Stage 3 Bully Clutch. Bully is a Canadian company based out of Ottawa, so I was able to get the clutch for my car in less than a week. They also offer 90 day warranty which will cover my summer time use, and they've assured me it will be able to handle my car no problem. So far I can say the clutch feel is very light, and the heavier rotating mass is noticeable through a now slower engine response, but it holds the power well. Haven't had the chance to really drive it hard though as I'm still under the break in period for another 350 km's.
