McLeod Racing Billet Aluminum Flywheel w/ Steel Insert, 6-Bolt (GM LS)
[560530]

This is probably the lightest flywheel that you can buy. The Fidanza is a little heavier but not by much. I have the RXT clutch so I really wanted to stick with the same company when buying my flywheel. The flywheel does present a little shudder because of it's weight but the aluminum should dissapate heat alot better and last a lot longer than the McLeoud steel version.
