Hi, I bought a second hand t56 and it came with the old clutch Its a VALEO Pressure Plate, exedy clutch disk that's 275mm in diameter and it had a alloy CSC Question Are: To me is that an 11" Clutch so not a factory clutch........Am I Correct? If it is could I get the flywheel machined and get a new clutch disk only? Last but not least..........are the alloy CSC's a re-useable Item because they are not plastic or are they just a more reliable throw away Item? Thanks
