A wheel adapter needs to be roughly 1/2" thick. It has to be thick enough to stick out past the 5x100 lug nuts to give a flat surface for the wheel to mount to with the newly adapted wheel pattern. Even the highest offset and skinniest wheel you could find would stick out far past the fenders.I’m looking at changing the wheels on my car but I can’t find any wheels with 5x100 stud pattern that I like. I’m wanting to change the stud pattern with a adapter/spacer. I have a 91 Camry and want 15mm spacers, what spacers has other people used.
