Whats this for? A friend of mine has the stock 16x8 Trans Am/ Grand National rims on his 86 camaro (inset is painted black). They're a very light, spin cast, aluminum wheel that GM had made in Japan. Make sure you get the ones that can clear disc brakes if you do this. I think Cragar is doing some different stuff now, Hell my nephew thinks Cragar S/S were some sort of dealer add on since all the 70s rod guys have em.
If you can't get the rim you want, what about something like a lightweight wilwood caliper and disc?
