Just for reference, I've booked in my car to a local VW specialist to have my clutch replaced with a Sachs SRE kit - been quoted £1000 - £1100 supply and fit. Clutch only, leaving factory flywheel as I don't want to suffer the vibration/noise issues associated with a single-mass flywheel.
£1100 for just a clutch fitted, holy sh$t!
Mate get a standard Luk or Sachs of ebay, take it round to your local indi and have them fit it, £500 max! My local indi fitted a new clutch my CTR for £70, the clutch cost £120 of ebay, no issues.
Surly you dont need a race clutch for a stage 1? Stage 2 onwards yeah.
