Definitely won't work. They would go inboard past even a mini-tub and sit 4 or 5" inside the wheelwell unless you widened your rearend a lot because the offset is positive and you need it to be negative. In other words, your mounting surface needs to be about 4.5" inboard when measured from the backside of the rim, aka backspace but the Corvette wheel is about 8" in from the back.

18s and 19s look great on 1st gens but the inner measurements are all wrong on the C6 wheels.
