Yup - some Golf R clutches are made of chocolate! Mine's on 24,000 and I think it might be slipping as the revs rise slightly when shifting from 5th to 6th although it could be the delay valve. VRS in Northampton are VAG gurus and do a sintered clutch for the R at £880 fitted and it can handle over 600bhp. I'm guessing one for the Cupra would be similar although I think the 4wd system, as mentioned, does make a difference.
