Thanks for the great and well written original post
Recommend for the Administrator and or Moderators to make this a Sticky in the appropriate maintenance area of this forum so everyone (regardless of BMW make can benefit from this), I like to add one item of note ... Vibration increases by the square of the speed (RPM) the result of course being the faster you go the more vibration you feel at the steering wheel ... and the longer you tolerate it the higher your repair bill will be eventually ... it goes without saying other related parts and components will wear and or fail.

I tend to agree with this if you think about it anything that is machined (both sides of course along with matching spigots on your spacers) has a machining tolerance. So accumulated tolerances of the afore mentioned areas will add up along with the original parts may just contribute to wheel position misalignment that would be on and above the recommended OEM allowable tolerances. The wheels being the most important part between our car and the road, I take this very seriously. Perhaps I'm overcautious due to my long engineering background, I see this from a different point of view. Your removal of the spacers and eliminating vibration may very well have been exactly what I mentioned before ... vibration due to accumulated tolerances (adding up the face to face squareness and run-outs TIR [Total Indicator Readings] etc.).

I get the vibration sometimes. Not every time. It makes me think it may be related to the braking somehow. Is it a rapid pulsing of the brake system vs. a vibration?

What speed? Accelerating, cruising or braking? Do you feel vibration in the brake pedal? Is the vibration rhythmic? Any recent changes to the car? |

If it's only during hard braking (but smooth on cruising), then obviously, it's most likely brake related rather than anything to do with wheels, tyres or suspension.
ABS pulsation is quite obvious as you can feel (through the pedal as well) and hear the high frequency blunt knocking noise as the ABS pulses. I would start by having your brake discs checked for excessive runout at your dealership or reputable mechanic. There is a good chance that your discs are/have (one or more of the following): 1) not sitting flush and flat with the wheel bearing 2) uneven pad deposits 3) warped due to wear and uneven skimming Note that spacers and larger/wider wheels/tyres will exacerbate any form of vibration around the wheel area, due to the fact that the wheels (+ extra weight) are further out of the car, which increases the effect of centrifugal force on the spinning axis. |

Personally I think if tire and wheel sizes are correct you should not use spacers except for temporary fine tuning.
Thanks for the info all. Since I put new tires on my car and removed the spacers it is 1000 times better. It seems to be settling in and getting increasingly smoother. Last edited by 4corners; 06-05-2013 at 12:50 PM.. |

Incorrectly installed or poorly constructed spacers can definitely cause vibrations but I don't see how centrifugal force has anything to do with it. I do realize that centrifugal force is in play as part of the vibration but having a wider wheel or moving the horizontal position of the wheel is not a factor on its own. The source of vibration from a spacer would be due to it not being installed flat against the hub and wheel (due to debris or tightening the lugs with weight on the tire/wheel), not allowing the wheel to be hub-centric (aka not centered on the hub), or not being of uniform thickness (same affect as not being installed flat against the hub or wheel).

Another fact, you are more likely to have vibration issues with ZCP (359) wheels than the 220 wheels because of the offset.

I got new PSS's on my car and upped the size by 1 and now my steering wheel has a minor vibration. I got it done at America's tire and they have lifetime balance for free. Problem is, everytime I took my car there, they f'd up my rims and scratched up my lugs. Even after I asked for hand removal some clown didn't use a breaker bar and f'd it up hard after yanking on it.
So the question is... do I risk them f'in up my rims and lugs again, and a hideous job removing the old weights and putting on theirs?

Good info thx , working on fixing my issue. Had tires rebalanced and still getting wheel shake around 75-80 mph on and off. It's weird I'll be driving it will be nice and smooth, then itll start shaking a little bit and then go away.
Interesting I have noticed that when I lower my tire pressures a little bit that the shaking is a lot less I was running 39 to 40 PSI and I lowered it to about 37 1/2 to 38 psi and the shaking was a lot less today interesting UPDATE: so after inspecting my suspension, and it all looked new, ive narrowed it down to the tires. went and got two new tires and issue fixed. my old tires ( 15000 miles from the factory ) still had about %50 left on them, never had a patch, never beat one. not sure why they had issues. they were out of round, but just a little. it was enough to make my wheel shake at 70+ mph. maybe the sidewall was coming apart, flat spots, who knows. so i turned them into perm spare for the front, still good to drive on in a pinch. but the new tires feel great, back on the road i go.....

I had a annoying steering wheel vibration at 120+ KPH....with Avant Garde M359 19's and Continental ContiSportContact 3 tires; and spacer set-up 15mm front and 20mm rear (hubcentric).
I put on new rubber - Michelin PS A/S 3's all 4 corners, properly balanced, and kept the spacer set-up the same. And now, my E92 rides smooth as hell, good grip in the corners, AND NO steering wheel vibration - EVEN with a bent front driver side rim (which I am getting repaired later this week). The Conti's were over inflated and the lug nuts were severely over tightened - cause of vibration and shitty ride quality. |
