All for naught as it turned out. I also bought the Mercedes fitment hub-centric spacers to sandwich this all together. Those were the only bits I needed. And they have, as I said, a very nice, snug fit to the ID of the wheels. And a nice snug fit over the hub on the car.
Please don't take this response the wrong way!

Keep thinkin'!
I'm at a loss. I just wish someone else could drive my car for 5 minutes. They would probably say "It's this, idiot!"
Max,
I occasionally have a similar sound and it is odd because it is not in line with the rotation of the wheels. I also did the coast at 70 in neutral and it does that uneven sound. I am assuming that It may be an alignment issue but like your car it tracks right and straight. THe only difference are my tires which are needing replacement for the fronts.
I am not sure but it definitely is an odd vibration that is not easily defined. I figured that with new rubber my problems may be solved but then again we seem to have a similar issue.
I have not figured anything out as of yet.
THanks.
