they wont work. U need +45 for the fronts if your gonna lower and +50 on 10" to go lower. 11" wont make it w stock ride height even at +55, UNLESS u did a super stretch but only at ride height, and thats a guess on my part. If your gonna go low 8.5 and 9.5 is easiest to deal with, a 10" rear like I said has to be a high offset. It also matters w diameter, 18,19,20 all need their certain profiles to clear. I do like the wheels tho, very classy. If you really like them you could run a spacer out back or fatter tire. I didnt see specs but if they are porsche spec wheels they really should be hub centric if your gonna throw them on a MB. I have a set of euro 63 that are similar and I love them, have them on now actually. They also make a similar wheel thats a flush face wheel, look around, they come in 9.5 and 10" rear I beleive w high offsets
