That's a pretty specific request on a car where, in my humble opinion, we already have somewhat limited wheel selection unless you're willing to use spacers. I think if you're willing to budge on the staggered sizes and go with 18" all around, or 19" all around you're going to have a lot more luck fulfilling your other requirements. If you're willing to go with 19s on the front and 20s on the back STR 607s come in 19x8.5 and 20x10, but I'm not sure what the center bore on those is...
I like the 18/19 for this car and since I in it 2-4 hrs twice a week did not want to decrease the sidewall. I have found a few sweet looking options for 19x8.5 20x10 with lips. Not just wheels we are limited on ALOT with the MB.
