You are right, these are aftermarket wheels. I believe these are hub centric wheels though. The wheels are made by TSW and are called Bremma's. They are a knockoff of the two piece AMG double 5 spoke wheels. I did purchase these off of a well know national wheel company that supposidly test fits these wheels, also TSW shows these as a direct fitment in their database for my car. I believe that by hub centric you mean that the wheels when mounted are centered on the hub by the middle ring and are not centered with only the lugnuts. This is the case and there seems to be no play or movement when mounted without the lugs. Any other thoughts?
