I also have a NPC clutch from Madaz, been in the car for about 15 months being daily driven and it hasn't missed a beat. ever.
Its a ceramic one, not sure if its 9.5 or 10 though, can't remember lol.
edit: while I'm here, I'll need another one shortly for my new R32, needs to be able to hold 260rwkw on a RB20, and needs to be RB20 gearbox friendly.... lol
I dont need it yet, but if you could chuck me a ballpark that would be good Steve.
