I have the uuc stage II moderate lightweight steel flywheel with the m5 clutch, while the clutch is heavier than the stock clutch the flywheel makes it so it is still much lighter than the stock combo, I have some chatter at idle which is louder when you put on the AC. I used a combo of two different redline trans fluids to help out with this and the sprung hub design of the clutch helps too. Overall I love my setup, my car (325i) accelerates so much quicker, smoother downshifts because its easier to match revs, the clutch peddle is obviously stiffer but you don't notice it after about a week
I chose the steel lightweight instead of the aluminum lightweight because my car is purely a street car right now and I wanted to have the quietest and most comfortable yet sporty set up I could, and damn is it sporty.
