shaking w124 wagon!!
metal or polycarbonate? pics soon after lowering the car and fixing the vibration.
Is the car's alignment in check? You should be able to visibly check this as vibrations like that would indicate a very large misalignment. You can always get a tape measure out and measure the front of the inside of the rim to the other side, then measure the rear of the rim to get the alignment toe spec. The front should measure smaller than the rear -- slightly 'toed' in.
Any play in the ball joints or wheel bearing? Grab it 9 and 3 and shake to check for play. Then grab at 12 and 6 and do the same. There should be no play, or very little.
Hubcentric rings are not your issue.
