I have a set of 4 factory AMG 18 x 9 inch wheels. These are factory AMG wheels off my 2009 C63. All four wheels are 9 inches wide with a 54mm offset - I used these for track driving but they would be good for a winter tire set-up or as a primary set of wheels. They wheels are all straight and true, but do have some curb rash so you would need to do some finishing work if you wanted them to be perfect.
