Bore size 66.6 vs 66.56
W210 E55 has 66.66 center bore and Mercedes makes wheels with 66.56 center bores too, not sure why?
I absolutely do not want to deal with bloody spacers or hub centric rings and all that crap.
would there any chance of vibration If I was to buy wheels with 66.56 center bore and mount on the car with 66.66 center bore?
Google search says they are interchangeable but I am not sure and do not risk buying wheels that don't fit
If the difference is insignificant, why would this company makes this adapter?

From a hub centric adapter manufacture (b2bfab)
Many aftermarket wheels and some OEM wheels require hub centric rings to downsize the center bore correctly center on the hub and to offer vibration free operation.
66.6mm is a common size for lots of 5x112 aftermarket wheels as this is the hub bore of many Audi and Mercedes fitments.
My guess is that the larger bore allows for a greater market range for the wheel. The usaadapter piece seems overly complicated for the task as a bushing might work. Good luck.
