Not much orf a surprise, the hub was setup for audi and VW which uses a different bore diameter. i forget the size. But most custom wheel shops have the tools to bore the hub to be hubcentric for newer model M.B.'s I had these bored to be hubcentric already. Tons of 16x9 5x112 wheels once you look for the audi/VW wheels. altho finding the right offset is harder.

On a side note the color code for these is hypersilver with a diamond polish lip. Not a ding or scratch on these wheels.
