What do you do when your late model vehicle comes with 20's? Change the brakes and put 15's on it?
Listen, not all vehicles need a lot of wheel, nor do all look good with them. The key is to have the overall package that works and that you like. That includes wheels. Running 13" or 14" wheels is silly and never looks good in my opinion. 15's are the minimum.
Mind you I run 15's on my dart, so I don't have a biased opinion here. Just a logical open mind.
