The bodykit looks like it is for the pre face lift CL55 AMG - the alloys are definitely replicas so therefore I am assuming that the bodkit too is probably not OEM AMG.
I dont think that there is a OEM design similar to those alloys - the ones shown are after market and are a "one piece" wheel made to look like a 2 piece. Still nice looking alloys BUT a bit too bling/barry (ish)....
Contact the seller and try and get soe info on the wheel.
