Hmmm... Not sure what I would do. The HRE's look like they'd be very similar to the C5R OZ wheels -- so, they could look really sweet. I just don't think I've ever seen these HRE's on a Vette, so it's hard to say.
I don't think you can get the CCW's in anything but 19"s (yet), can you? I heard rumors that CCW was going to entertain the idea of making 18"s, but I don't think they have done so yet. Anyone know for sure?
Maybe someone could photoshop some big HRE's onto a Z06. I think they could look sweet.
