Geesh, if you couldn't figure out what he was talking about from the pictures, you shouldn't have posted anything! Well designed spacers like those show are fine, just be sure to retorque after the install and a few hundred miles.

I ran 1" spacers until I could find the right wheel as the AMG wheels did not line up with the fender as they should. There is no more negative effect of a spacer over a comparable offset wheel - they both change the geometry and increase the load on suspension components but when done reasonably should not cause any huge problems.
