My clutch isn't actually going, but with the tuning box on it cant really cope. Nothing majour really as i don't need to have it fitted. So I've read about dual mass flywheels, and how much they cost. Is it a huge job for this? Normally I'd go for DIY but don't think I'll be doing that anytime soon. Whats the average cost for it fitted? Seen them for 160 quid for the clutch. Then fitting after that. What are the chances of it needing a dmf?
