I had a set of hardened alu. Hyperplates in my clutch. Seemed okay before I put the Yoyodyne slipper clutch in. This past race weekend I kept noticing that i was hitting a lot of false neutrals between gears... kept getting worse & worse. Before my finals I decided to pull the clutch and see what was up.
All of the 5 metal plates had scorch marks on them... 3 spots on each plate roughly 120° apart. 3 of the metal plates had fractures in those same 3 spots per plate. A simple flex was all that was needed to snap the plates. The cross section showed the scorching went all the way through and weakened the plates severely.
I figure that the clutch would likely have grenaded at some point, locked up the wheel, and launched me into low earth orbit. I'm glad I caught it when I did.
I should have known better... from now on its OEM plates (fibres and steels) all the way.
I'll try to post pictures soon.
