I'd pointed out awhile back about this, but, yes, on TGMPG's site, there are indeed two wings.

There's the CF wing the 1LE ZL1 all have and then one just like it, but in the semi-gloss coating like the other parts of the car. I've only ever seen pics of it and had previously asked questions about not only of its existence, but that it has a part number, so it's like it was a scrapped option or an unreleased piece for something.
If you look at the bottom of the link above, you see pics of the non-CF one
