I have a Fidanza aluminum flywheel. I like it just for the fact that you can replace the surface with a brand new piece when you change the clutch.
You don't have to take it to the machine shop and you never have to worry if it's too warped or cracked to be repaired after each clutch change.
I can't make any before and after comparisons because I changed too many things at the same time.
When I first installed it, I had a SPEC Stage III clutch that was like an on-off switch. Having an aluminum flywheel certainly didn't help. I got tired of looking like a jackass, so I got a more streetable clutch.
