The Wheels I decided on for the Scamp 17"/18"

With 18" on front also. IMO 18" looks too big on the front of these cars unless they are pretty low.

I think you might find most of the members here feel 18s are too big on these cars, no matter what

I wouldn't worry too much about them, its your car and your making it the way you want it
that's cool in my book
