You'll have to watch the offsets with the Vette rims - my '68 was graced with a set of them when I got it, rubbed in a few places. I always liked the big and little approach to wheels and tires until I started the originality/restoration routine, so I replaced the Vettes with DF (correct) Rally wheels. Of course, originality comes with a price nowadays. Thank goodness all 5 of mine have a full sset of 5 correct rims.
Cutting it short, that's enitrely your choice. Restored means restored with OE parts, Day 2 is a modified. Day 2, do what you want. You can always change back to have the car judged -
