I have a set of MAS Italy 19x8 et 20 5x112 wheels for my allroad (picture in picture poster) that I purchased prior to my knowledge of "center bore" and "hubcentric" concepts. I was initially enthused because I would not need spacers but I have since found out that the center bore is 66.56mm for mercedes. I have been having no success in finding a centering ring for this dimension down to 57.1 to fit our cars. The tire rack did not have anything and I have run out of ideas short of selling the wheels. Any ideas/advice is greatly appreciated.

You could have a local machine shop cut some for you, a pretty simple job if they understand the concept and have some aluminum bar stock in the right size. 66.56 OD by 57.1 ID, with a taper on the ID to fit the hub, and thick enough to fill the space in the wheel. I'd offer to make you some but I think shipping would be more than they are worth (I'm in Canada)

I don't know how to go about finding a place to have some machined. I'll give it a shot but maybe I'll take you up on your offer and I'll just deal with the shipping costs.

thanks again
