i would say do NOT go aftermarket the stock flywheel is best.
now why i think so well because the aftermarket flywheel has an "adapter" bolted to it so it will fit on our car. Well that adapter make the entire clutch assembly a quarter of an inch too thick so when u don't have the clutch pressed the lever that moves the clutch away from the flywheel rubs against the clutch housing. now this only happens after the clutch wears a little.
