wow.....umm.....wow......if you really are talking about a Flywheel (which is encased in the bell housing of your tranny, and couldn't possibly get curbed) I hav an aluminum one from Clutchmasters and it kicks ass. you motor revs quicker, but the revs also drop faster, due to no inertia carrying the crankshaft round & round, so it kinda makes you shift quicker.
