For reference, I had these in 20" w/o gunmetal and no lip on my 08 E350. You can check my pictures in my photo album. However, BEWARE! These are replica wheels the RS models, and they do bend easily!! Also, if you curb one of these wheels, they can be repaired, but not perfectly. The outer lip area is made of a thin thin sheet of metal that cannot be replaced and is hard for wheel repair shops to work with. Really doesn't come out how you want them too. Additionally, I had these on the car for a total of about a month maybe less. NJ roads are bad but I know how to avoid those pot holes, and still, two bends, one so bad that the outter rim buckled in two places. not trying to scare anyone, but you should no whats up. I obviously liked the wheels enough to purchase a set, so I can't blame you for wanting them either. Additionally, I may let my set of discontinued all sliver non/lipped version of these wheels w/ tires go for a crazy price in the classifieds section so keep a lookout. I believe they are 20x8.5 all the way around as I have a 4matic. The bends (2) can be fixed and the refinished wheel that was curbed I'll be sure to post pictures of. Its hard to notice unless you are looking for it, but of course the owner is always looking. Good luck guys.
