    Slight wobble with BMS spacers & car lower??

    I installed my 15mm rear spacers a few weeks ago, and immediately noticed a slight wobble when easing off at 140km/h, and also a more intense wobble at 180km/h.

    So I removed the wheels, re-set the spacers, spun them around a few times to ensure even distribution of the anti-seize.

    This worked fine for a few days, then the wobble returned. Just to check, I completely removed the spacers, and the car was smooth as silk at any speed.

    I really want to keep these on, because the look is fantastic .. any ideas? I've cleaned, torqued in the star pattern, etc etc.

    Also, my car seems to sit lower now .. before I could just about squeeze my floor jack under the rear jacking points .. but now I have to reverse onto a plank of wood to get the jack under! ? I don't really want to figure out the math, but is this what happens when you push out neg-cambered wheels?

    Sounds to me like the spacers aren't perfectly balanced.

    I suggest asking Matt@Camber-Toe what can be done to eliminate the wobble.

    Hmm I just installed my BMS rear wheel spacers and I can't tell if it's wheel wobble or my HPFP is going bad again...but it wobbles also...didn't notice it before, might've been there but just never noticed it. I need to log a run to see if it's the HPFP, boost leak, or the spacers, but let us know how you fixed/what the problem was! GL

    I came to the conclusion that it must have been the anti-seize -- I re-set the spacers again, drove a few hundred km's, and for the most part, my wobble has resolved itself at all speeds.

    Yeah, I'm thinking I was a bit over-generous !

    Ah ok...I might try to re-seat my spacers then...btw can you describe the wobble a bit? I have a weird wobble that's kind of hard to explain and it seems to change quite a bit while driving...
