Camber / Toe issue
Hello folks, new here....
My lovely BMW has a minor issue. I've found out that there are quite a lot of suspension "wizards" in here, so i'll try and post the issue, and maybe get some positive response. My car is an E87 from 2008. Shares the same suspension as other 1'ers to my knowledge. Any way. Previous owner has slided in to a kerb during last winter. Wheel replaced, nothing other damaged found by BMW. I however did an alignment when i bought the car (i always do that). Left rear wheel was not possible to get more than -1 camber, if TOE was to be within specs. Regardless of how hard the technician tried. Right side was no prob. It seems that camber can be adjusted to quite a lot, BUT the TOE then slips. The camber arm (big alloy thing) has been replaced, no change. There is NO visual damage to any arms, OR the subframe... Any advice ?? |

Something is bent. Could be the toe arm, or one of the two upper arms if you have already replaced the lower arm. A good shop should be able to take a close look to find out which one(s) may be bent. It's also possible the subframe slipped toward the other side in the impact. There is some slop in the 4 bolts that hold the subframe to the body, so that may need to be adjusted.

What impacts camber the most would be the upper wishbone or the lower camber link. The lower camber link is a flimsy stamped steel piece so I would look at that component very closely one more time. |

Hello.
Well, the arm for adjusting camber HAS been replaced. Camber kan easily be dialed in to specs. But then toe slips. Im no wizz in This field. But it seems the toe-arm is too short, so to speak. When toe is at spec(maxed out). I can at the same time only get -1 degree camber. If i go for more camber, toe slips and wheel starts to point outwards. (if i remeber correctly)

But looking at my alignment paper, toe starts to go negative (wheel point outwards) when camber is dialed in to specs (-1.5 degree).

The subframe is bent where the toe link bolts to it. I see this a lot, it's really weak there. It can be corrected by a frame shop, or a port a power (basically a hydraulic jack with a variety of attachments). The other solution would be the Rogue/HP style links with a greater range of adjustment.

You have to look very closely and know what you're looking for to notice the bend. Even still, it tough. It really the only thing that can be bent based on your story.

Yes along the welds on the top and bottom. Typically if there is a bend, looks closely at the interior corners of the welds and see if any paint has started to flake off. If the paint is cracking or coming up at all, that's a good indication the metal has been bent I that location. If the alignment "isn't that bad", what does that indicate? Can you post the alignment sheet?

Here are the before alignment. One note!! BMW (amateurs) had replaced the damaged wheel with a 195-55x16" and not the correct 205-55x16". It actually made the camber a little worse (not much) Here are the after alignment with 18" 261's . The rear alignment was set for the same specs in both sides to make the car handle equal. |

I don't think you have anything to worry about looking at those numbers. They're balanced, and within specs. Especially for maximum tire life. Call it good!

But as written earlier, camber and toe on left rear is not able to get spot on. Max camber is ~ -1 and toe just around spec. If going for -1.5 camber, as pr. Spec. Toe drifts out. Right side is no prob to work with. So somerhing is not 100% as it's supposed.
