If you're still having vibrations, try re-clocking the spacers, 1/5 turn at a time. Yes, it's time consuming, but it should work. I was lucky, in that I had no vibrations/wobble whatsoever. We had to do this to a buddy's rig. Third time was the charm, fortunately, it was only one wheel that displayed the issue. If you can isolate it down to the wheel, that would help a lot.
