Nismo Gmax Twin Plate Clutch question

[EM.TT]

So I just bought a jdm motor, pulled the trans off, and turns out it already had a red Nismo Gmax twin plate clutch. The problem is, that right there is literally all the information I have been able to find about it. Can anyone give me some details or a link to more info? Also, how do you know when a clutch like this needs new discs? They are thinner than a normal clutch plate obviously, but how thin can they go?

I have never even heard of that clutch. Sorry.

lol, it's alright, I found some information on it. It looks almost identical to the Exedy Racing Twin Disc Carbon Clutch that Z1 sells and if I remember right it actually had Exedy engraved in on it somewhere. I thought having this clutch would be awesome, then I found out replacement discs are 300 a piece... Oh well, as far as I can tell this will be the only clutch I'll ever need!
