    Thumbs up Great excuse for e90/e92/e82 owners to upgrade to M3 Control Arms for cheap!

    Went in for an alignment, couldn't do it since the Notorious FCA Bushings popped, shops quoting around 385 w/ labor to replace bushings with stock 335i ones that will pop again.., thought I'd upgrade the whole arm to the M3 arms since the labor is cheaper. Found both arms for $176 with free shipping, cheapest I could find anywhere! Labor will be 1-1.5 hours or if you have time its easy to do yourself so itll be much cheaper than what they quoted for stock replacement and Im getting an upgrade! Thought I'd share, got em at importecautoparts I passed on the lower wishbone arms for now since I didn't really care for the neg. camber and didn't want them to have trouble with the alignment.

    Part numbers 31 10 2 283 575 and 31 10 2 283 576

    lame part is the damn shop scratched all four of my wheels mounting new hankook v12s so now have to wait for them to refinish them and remount/balance/install control arms/ then finally get an alignment and feel the difference

    I've been looking into this upgrade too.

    I just lowered my 330xi on H&R coilovers but since that setup is much stiffer now, I get a sea saw effect.

    I've heard replacing the rear subframe bushings can help solve this sea saw feeling but at the same time I would like to replace the whole rear end suspension with the possible exception of the camber links.

    The M3 arms are lighter, I noticed a difference holding them in my hands before they went on my car. They really, really make the front end eager to turn in especially since they will add -.75 degrees of camber and you can feel a lot more through the steering wheel. The first day I put them on, there was an almost annoying amount of steering feel (to the point that I thought I might have regretted my decision) but the bushings soften up a bit after a day or two and then they feel perfect. I had mine for 10-15,000 miles and loved every mile, but I wish I had also done the rear subframe and maybe even the rear arms.

    FYI, the link you provided are not OEM and made by TRW. I'm sure they work fine, but just thought you should be aware.

    ECS also sells the OEM version:

    http://www.ecstuning.com/BMW-E92-335...rade/ES257469/

    BUT it's cheaper here:

    For sure. Just giving more information just in-case anyone cares.

    I'm not saying TRW does this, but sometimes these types of manufacturers will resell parts that don't meet specific testing requirements imposed by the mass buyer. Again, I don't know if this is the case here, but just food for thought!

    Th
    ey ARE oem, trw makes them for bmw.. They are not OEBMW, but they are the OEM for these particular components

    100% identical, i even have a set right next to me.

    i spent waay too many hours researching this and sending tons of emails, i should know

    The one dfference is the ///M has been filed off all components (as theyre not sold by bmw lol)

    ed: and at the above comment, i have more than one email (and a phone call) saying they're exactly the same off the same lines, no cherry picking for bmw, these are parts that could have been in an m3
