I can't say for sure because I haven't dealt with any of their foreign stuff, but typically they'll use the same hat and put a different diaphram in them. This may or may not be the case. I've seen the oem replacements or "stage 1" as some call them, have a little bit stiffer pressure plate, and an organic disc. If you have any specific questions, I would call them and find out exactly what it is.

Either way, most of the hats are the same, regardless of which clutch. They just have different diaphrams in them, which is where you get your clamping force.
