Ahh, yes, Luke. He WAS very professional and knowledgable when he sold me my Carlsson's (when tire rack was closing out the line) and answered several offset questions for me prior to when I was exploring other options. Mabrams, the very BEST thing for your S-class is to order a rim specifically offest for it. My rims won't straight fit any other Benz. Merecedes never recommends spacers and Luke recommends nothing more than 5 mm thick. That will keep it hub-centric An E Class wheel will require a 10mm spacer. If you can get a lest a 40+ offset wheel and lug hardware, (as mine are)it will fit fine. But as previously suggested, a talk with Luke is well worth you while. Feel free to copy this and ask him to confirm. Good luck [^]
