I had hubcentric rings fitted with my aftermarket wheels after enduring the problem for many years, and the vibration immediately disappeared.
I would also look at the idler arm. Cheap part, and excessive wear will produce the vibration you are experiencing.

I agree, since the wheels are AMG's I don't think that is the issue either. I went driving last night to evaluate the symptom further and it appears to be only vibrating between 45-65 mph...past that it goes away completely. I plan on doing some serious undercar examining this weekend and hopefully that will reveal the culprit. I also checked the LCA bushings and they appear to be snug and in good shape. Again, thanks for your input and advice.
