But the bottom line, I would bet lots 'o money that GM will not use these wheels (from a fairly small aftermarket wheel company like CCW) on the production Z/28, which is a shame.
They might, if the Z28 were a limited production run. But with GM in the financial shape it's in right now, smart money says they'll try to sell as many as they can.
