WELL, I HAVE TO TELL YA, THIS...JMT23...try the search feature first, look for wheels, spacers, suspensions etc...you will find most are trying to lower theirs, but you will be going a different direction by trying to go big, so you may be the first to do that. You will be limited on rim selection with a mercedes bolt pattern...I wish you luck, but you may be in a lone situation here...22s are the biggest I have heard of...but I can't imagine them being bolted up, without adaptors...and spacers...again good luck...
