guys i have a used stock clutch here. It looks like its in pretty good shape but i'd like to know what the specs of a new one is so i can mic this one out and see how much life is left in it...

anyone know what the stock disc should mic out to?

 

The stock disc measures about 8mm with the cushioning compressed. You can either squeeze it down with a pair of micrometers or clamp it in a vice and measure near the jaws with a pair of calipers.
