G50 Carbon/carbon clutch?

[Igor+]

Could you recommend me any brand, please?

It looks like the biggest problem is a starter ring gear fitment...
A ring should be fitted on a clutch assembly.

I use tilton tripple plate clutches in my 993rs and 993 cup car.Fantastic 5 & 1/4 inch plates.
They also do a superb lightweight flywheel with starter ring all as one peice.And best of all,convert the clutch to a push type with a clutch slave cylinder inside the bell housing.All supplied as a kit for the 964/993/996.
Very reliable,and & saves a hour on a gearbox or clutch change.
Not for the road though,but saying that i drove my rs to spa and the ring,and it was fine.But brutal on take up!
