Well after about 2,000 miles or so on this setup I have come to the conclusion that I absolutely love the flywheel but the clutch on the other hand is a little iffy. The clutch chatters A LOT and if its not chattering is humming. All of this only happens when starting out in first to get the car moving. I am running about 8 to 9 PSI of boost (supercharged) so I needed the extra holding power but I think I am going to go to a STG 2 or Ironman setup after this.
