Couple of things to try:
I got my 12.5mm Turner spacers to stop vibrating. It was difficult, but it took a number of things, each of which made a slight difference, but only together fully eliminated the vibration. There are a finite number of things that can cause a vibration and you have to use a process of elimination to figure it out. As you've found, these cars are VERY sensitive. Good luck - I *HATE* vibrations. |

Macht Schnell as a company pisses me off. Their "engineers" made spacers that don't fit and created a huge safety liability for anyone who put them on their car and completely failed to even try notifying those who spent a lot of real money on their shoddy products. Stay FAR away from this company.

OP said the issue was corrected by MS swapping out a set of spacers, but we never got to see what the issue was.
Considering all the leg work the OP did to try and fix the problem, I would bet with 99% certainty that the spacers were machined incorrectly. I have a set of spacers that "appear" to be identical to the MS ones (I'm sure many are made by the same manufacturer) and I had a slight vibration as well at speed. After measuring the CB of the spacer it measured to about 72.40 mm and not the 72.56 that the BMW CB is. Now this is such a small variance but would exacerbate at speed causing a shimmy. |

I've had 3 different companies (MS, Turner, Rogue) and they have all had some degree of vibration more than without spacers. Spacers are a last resort. I refuse to use spacers on the front end now. Rear can be OK with good wheel balance since you don't have to feel it through the steering wheel. |

These spacers just don't have the chamfering done properly. The only fool proof way to do spacers is via a stud conversion and flat non hubcentric spacers. I'd stay away from the other ones unless trial and error and sketchy vibrations are your thing. |

This is common when a control arm bushing has failed. You will get a resonating effect which causes vibration and turning the wheel slightly will load the loose/failed bushing and smooth the vibe out.

This problem above though is isolated to the spacers. What is happening above is that the left front and right front can phase in an out of being crooked in sync with each other. That's why on highway drives, with two misaligned spacers, you can feel little to none and 4 minutes later your watch is trying to vibrate itself off your wrist. |

I'm still not following you.... I'm on board with the stud conversion. I however still think hubcentric spacers are best with or without the stud conversion. Are you just trying to say that you recommend studs with spacers?

Spacer are crap to be honest, I used to buy spacers for my wheels because I want to have a flush look, but ended up with the vibration, it is not from the balancing for sure. Just throw the spacers into garbage and get some wheels with the right offset. If you still have vibration without the spacers, get an alignment check. SPACERS = Vibration IMO.

yes, if a stud conversion made the wheels lug centric, but have you done a stud conversion?? The studs are small and thin and you still need the wheel hub for hub centric mounting

Hmmmmm. I have a feeling that the slight turning is a clue in this mess. It is certainly taking load off the vibrating component allowing the ride to settle. I suspect a failed FCAB bushing would expose itself in ways other than vibrations at high speed.

It is one of the symptoms, and it can happen at highway speeds only. I have my own BMW repair shop(15 years and 25 in the trade) and have experienced this countless times. I was just making sure you eliminate all possibilities. Good luck with this.

yes, jack up the wheels and put a pry bar on where the wheel/suspesnion points. You should be able to move it slightly; anything more would indicate worn bushings. |

Installing studs doesn't automatically make a wheel lugcentric - that takes a special brand of stupidity |

put wider tires, factory 265 tires stretch too much. I have 275 PSS on them, and they look much better on the car, imagine if you put 285 or 295 tires, it will be perfect and with 0 rubbing. The thing is that rear spacers will not cause you wheel vibration. Just buy two rear wheels and put in the front, it will stay flush with the fender and gives you that deep concavity.

clarity was not my strong suit yesterday. Yes, what you are saying is what I am saying. Of course you need a hub of some sort for the wheel to sit on whether you're using studs or not. |

Cool, I agree that spacers work far better with studs.
