i cant tell you for sure which ones they are, but i do know that my flywheel works great with my c/f dual friction.
i think the tech at fidanza told me that it works with almost any because it has a steel insert. if i remember correctly some fly wheels have an aluminum insert which doesnt hold up to some clutches. another good thing he told me about the fidanza is that if it does go bad u can buy a new insert for 60.00 instead of a new flywheel like some of the other big name ones out there. thats IIRC
