Exedy's new billet steel flywheel weights just 16.5lbs. It is only 2lbs heavier than the aluminum units out there but since it is single material you wont have to worry about the harmonics. Plus the MOI has been reduced significantly so you get even better performance from this unit.
Exedy went the extra step and got it SFI approved as well. This flywheel is sick! You have to see it to beleive it. They also have directional veins at the core to diret air flow away from the center to reduce hot spots on the mating areas.
Their Mach 400 or 500 work great for the street and have very little to no chatter in 1st gear.
Hit me up if you have any tech questions or need any more info on the Exedy line.
