Question about Wheel setup
Scott
As for wheel size and rubbing, 18" x 10.5" all the way around is rather large. The GM 302 Concept Camaro had 18" x 10" all around, so they fit. The only reason you'd need spacers is if you got the wrong size.
A good custom wheel maker should have that covered, spacers are a make do when trying to fit wheels designed for one type of car onto another.
