I've seen several places indicating the Excedy and Cusco twin discs are the same. I've also seen indications that the Cusco unit has different discs with more carbon in them.
Can anybody verify these?
Also, any problems with either of these?

 

Nobody has input on this?

 

they are both freaking expensive.... sorry Ive never used either only clutches Ive used are south bend and ACT

 

My twin disk Cusco were stamped Excedy.
