    the 50-60 shimmy in my 525i

    changing the upper arms and tie rods helped alot but didn't cure the problem.

    all tyres changed and balanced
    all brake disks and pads changed

    next?
    im not sure!

    i have 16" replica wheels


    seems like all coming options are going to be costly.
    im thinking new original wheels, or replacing other suspension parts.

    can't do both together right now..
    so what do you guys think i have to do first?
    save up for new good wheels
    or replace other suspension parts?

    many thanks

    You in Oregon? I'll give you my old bottlecaps that I just took off for 50 bucks. They work great, just not as beautiful as my style-5s.

    Have you always had this shimmy?

    I remember having a vibration in my car caused by the two-piece driveshaft being assembled out of it's original position, imbalancing it, but not a shimmy.

    When you had tires put on your car, did they remove the stickers from the tires before balancing? If not, make them do it again. My Paps used to balance his tires when he worked at the dealership and the sticker actually weighed alot and the wheel would become imbalanced after the sticker came off the tire. The other guys didn't believe him until he ran the tire with the sticker, then removed it and ran it again. It's comical seeing guys leave tire shops with Corvettes and Vipers where they left the sticker on the tire. Not safe!

    do you know about Hubcentric rings? These are alminum rings which fit over the wheel hub onto which you put the wheels .Theyprevent the offcenter tightening of the wheels and completely fixed my 50 mph shimmy when i first got the car.I contacted Rondell, the manufaturer of my wheels and they told me The rings have to be 74.1 to 72.6 and the name is ZRH for my Rondell 58's at 17x8.5. maybe since these are aftermarket wheels you need them as well and the wheel manufacturer could give you the right size.

    if they work better than my wheels i don't mind buying them and putting them on Temporarily till i save some cash for new wheels.

    50 bucks is a good deal but can you ship them to middle east for free?

    thanks
    you just gave me an option to consider

    also, did you have the transmission and engine mounts replaced? even a single mount on my engine made a world of difference.

    get your wheels checked for roundness and straightness.A small bend can cause ashimmy in these cars.Most alloy wheels can be repaired very successfully,but they need to be done by someone who knows what they are doing.See if you can borrow a set of std wheels and tyre in that are known to be good

    yes Angry
    i had this shimmy since i got the car a month and half ago
    funny thing i didn't notice any shimmy when i test drove the car for like half an hour before buying it!

    yes stikers were removed then tires were balanced.

    was your vibration noticable only in the 50-60 mph range?
    my cars goes just fine before and after that speed range.
    i think i will take a look at the driveshaft to make sure everything is in the right position.
    many thanks

    will have to check wheel bearings althou i don't notice any sound but yes they might be shot and i have no clue when the last time they have been changed.

    i will let my mechanic look at the drive shaft aswell..but i am not sure a bad guibo/center bearing cause vibration only between 50 and 60 mph

    Jehu
    i don't know much about hubcentric rings.. does it work like a wheel spacers?
    excuse my ingnorance

    last week a friend told me he bought a costum made wheel spacer ring from a turning shop (a shop here checked his wheels and made him the rings)..he claims they work fine on hes 17" replicas and they solved hes high speed vibration..maybe he was talking about hubcentric rings?


    since this is not a costly option i will give it a try but honestly i don't know where my wheels come from!
    can a shop measure what hubcentric size i need? and do you thing doing them in a torning shop is a good idea or is it more complicated for thsese little shops to get perfect?


    thx for your help guys
