I would tend to think that they are not going to fit w/o rubbing on the inside, especially in the rear. Just for comparison, a 17x11" rear GS wheel has an offset of 50mm so these are going to sit in an additional 18.5mm.

50-56 mm are the perfect offset for your vette. Because the Fiskes are 68, they will sit at least 1/2" further into the wheel well even if they don't rub. Not sure if you'll like that.
Your other option is to get 3/4"-1" hub-centric adapters (or spacers). I'd choose the adapters because they don't require changing studs and are more easily reverseable. Plus, I think a good billet adapter is probably better than a spacer (safety).
Do a search on adapters or spacers in this forum and you'll find posts where I explain why less than 3/4" changes aren't a good idea.
If you use 3/4" spacers or adapters, your wheels will protrude very slightly (about 1/2"). If this or the internal problem of rubbing doesn't excite you, go a different route!

I don't know.
Are they local, can you try them on?
What were they on before?

I remember reading that to fit a 11 inch wheel within the fenderwell of the Vette you need a 8.3 inch backspacing. Well, if my math is right you have exactly 8.22 with the Fikse. And they are a company that will custom fit them to a certain vehicle, so I imagine they are right on in the rear.
I narrowed my rear and additional 13mm, and mine are almost flush with the fenderwell with my 50 mm offset GS wheels. So Imagine you will be spot on.

The above link shows the 11" GS at 50mm offset, I have them on my 88 and on a really, really hard day doing laps they did rub. Only on one side think I need to look at a possible problem on the suspension!
