They have a super light 8 pound flywheel, and I'd like to put a light flywheel in next time I do my clutch (nuther year or so), but...

I've read posts here about flywheel bolts backing out becuz the aluminum flywheel expands and contracts at a different rate from the OEM steel bolts. Obviously, this is bad. Does anyone have experiece with the Unorthodox aluminum flywheel?

My other option would be the Zex 10 pound flywheel, which is steel. Still really light compared to the stock CRX flywheel, and about the same price. Any ideas as to which unit would be better for a car that's street driven and raced as well? thanks
