F80 M3 full front arm conversion for non M 2,3 and 4 series

BIMMERPOST / Classifieds
Asking Price:
USD 425.00

Item Interest
All four F80 M3 front arms for conversion for non M 2,3 and 4 series. Includes custom made stainless spacers for the forward arms per the thread on the 2 series side. These have never been installed, another project I've been sitting on. I do not have the headlight arm as my car does not require one. These arms are made my Delphi, not sure who the original supplier for these arms to BMW was but these appear to be no different from OEM minus the markings. I am not sure if these are compatable with x drive, please do your own research. Asking $425 shipped for everything.

Hi there! Would you be able to post the part numbers? I was trying to read up on the arms but couldn't find them.

No. Its also not as simple as the E90 swap. The front thrust arms are longer so they push your wheels forward in the wheel well.

That is only the case if you donít use the forward tension arms.

M3 arms are not compatible with xDrive. They cause the front driveshafts to break almost instantly. See Kies Motorsports video.

Also Lemforder makes the control arms for BMW. The front control arms for RWD and xDrive are different part numbers.

This is not accurate. I have both the lca and thrust arm from the f80 on my f30. First, the lca is what pushes the wheel forward, not the the ta. Second, adding the ta does not meaningfully push the wheel back to center.

That said, the wheel is only moved forward about 3/4 inch so not that big of a deal unless the car is slammed in which case likely doesnt need any handling improvement mods because it will handle like garbage anyway.

I can confirm this. I have both on my car as well and the TA does push the wheel back but its not much at all.

Hey oksymoroni,

Just curious and what's your current wheel/tire set up? Looking to get these, but I'm afraid I might rub.

How much does this really help with handling coming off of M-Sport with just some H&R sport springs

OP hasn't installed them, but look on YouTube for people who have installed the conversion kit or the straight lower control arm. Several have said it's one of the best handling upgrades they've done. The straight LCAs with spherical bearings alone provide noticeably better handling, negative camber, and longevity.

Still for sale but if they sit around much longer they will eventually end up on my car. Only selling these out of laziness.

Did anyone really install the kit? The F2x drivers talk about liner rub, does the F3x has the same problem?
