I'm right there mumbling with you. Mostly under my breath and things I can't post in open forum
but I'll get'er sorted. Your comment is pretty much what I suspect at the moment. The flywheel is aluminum. The floater isn't. Must be a hardened steel. The floater guide bushings are mounted on the aluminum flywheel near the outer circumference and the location of the centers will change as the flywheel grows. The floater doesn't have a lot of places to get rid of heat and is contacted on both sides by friction discs where as the flywheel and pressure plate only see contact on one side. The flywheel and floater will expand at different rates due to the dissimilar materials and different heating. It may come down to whether there is sufficient clearance in the guide bushings for the floater.
I hope I'm overthinking this a bit and it turns out to be something else, because I'm not too enthused at the prospects of having to pull the clutch and open oup the clearance on the floater plate bushing holes.
