Cost (in addition to smoothness) is probably part of the reason OEMs avoid light flies. But not so much cost of the flywheel (steel inserted al flies asside) Ford could have easily designed a cheap light nodualar iron fly that was even lighter than SVTs has for same money. But they would need to upgrade the clutch, differential, and syncros to meet the same durability goals. And if you buy such a fly, be prepared to do the same..ie. HD clutch, Quaife, bulldog box or late 2000+ syncros..





Thanks for the info.
