"... you change wheels the problem comes back", that's the biggest clue it is still with the wheel assemblies. Besides still having balance issues, mounting accuracy, run-out, tires are faulty, are possible issues.

A general observation, "design flaw" gets used, I don't see that, or all cars would suffer the same problem. There is the possibility the 'tolerance stack' for a few builds are contributing to a problem. Changing something that 'rotates', can reduce, or amplify the issue.

There have been similar vibration issues with the F10 models, a few persistent, with no apparent solution. Usually a change in intensity with wheel changes, balancing, etc., even if not cured. Other examples no issue at all, even as miles are added.

I recall one F10 user had gone through all sorts of attempts (changing wheel sets, multiple balances) for a solution. Never completely eliminated the vibrations. Then with a routine tire change, problem completely disappeared.
