So I have been looking for some OEM rims to run on my SRT-6 coupe for a different look for cheap and found some AMG staggered rims that would be great BUT they are 18" and the seller is saying he thinks the rear caliper will hit and they will not work. offset is perfect and they are cheap but I cant run spacers because the rears are already 45+ . Can you run 18" on all corners or do you have to have the 19" to clear?
