I've got a 17 Golf R with manual and Stage 1 Unitronic tune. My clutch has been slipping on occasion. Noticeable on hills in 4 and 5th when I start getting on the gas. I've searched and read previous posts, but don't have a clear idea what I should opt for. I'm looking for a good daily setup that wont overly change the refinement of the car. I've heard single mass causes chatter...some say you barely hear it. I'm willing to live with a small amount of noise to get a clutch setup that i can launch hard on occasion...but I don't want a car that gets ugly noisy and hard to sell in a couple of years.
