Double check what oldskewel is showing you. There is an adjuster at the bottom rear of the lower control arm (a-frame) and one at the upper front control arm which you can't see with the tire on (which is why I think the picture he posted is taken upside down of the upper one,) One of those has slipped (or turned) on you.

According to BMW toe is primarily the bolt on the inner bolt of the "swing part". Camber from the upper forward control arm. They both affect both. The wishbone affects both. (not adjustable).

[mention]RocketyMan [/mention] make sure to include both back wheels from directly behind so I can get a horizontal references from the bumper.

Are you saying #6 does mostly camber? I thought that does toe since #11 is non-adjustable. Therefore, #6 would adjust the toe as it pivots about the same plane of #11. I understand the swingarm that both bushes adjust a little of one or the other.

7 is the eccentric bolt for camber. 18 is the eccentric bolt for toe. 18 effectively moves the bottom of the wheel carrier fire/aft. 7 pushes the top front of the wheel carrier in/out Since neither are on a horizonal plane, each will affect both. It's largely why I didn't do my own rear alignment while I have no concerns doing toe alignment on the front.

If the springs did any settling that would usually be in the first few miles after installation. That is, unless you have been way overloading the springs recently. I've had H&R springs for many years--no settling.

Regarding toe vs camber alignment back there, the forward upper control arm is called the "guide link" and its eccentric bolt (#7) and washer (#8) are for primarily adjusting toe. The lower control arm is called a "swing arm" and the eccentric bolt (#18) + washer (#19) on there are for adjusting camber. I probably have bolt and nut sizes and torque specs in that thread. There is some cross-coupling of toe and camber, so you iterate between the two. Also toe has a much tighter spec than camber, so toe is the final one to be adjusted. I have done both toe and camber on my car, probably reported details in that thread linked above. Distance from the underside of the fender lip to the underside of the lower wheel rim will be only very slightly affected by camber change, so I believe the measurement will still be sufficiently reliable. Main purpose of that would be to see if the rear is still 1" lower as you modified it to be, or if it has dropped lower, which would explain some camber change. To measure camber accurately, my method is to park it on flat and level ground (at least side-to-side), and use a straight edge on the wheel rim edges, measuring camber angle (relative to gravity, but since ground is confirmed level, it is a direct measurement) using the Klein Tools 935 DAGL, which easily gives better than 0.1* accuracy. https://www.kleintools.com/catalog/l...ammable-angles

As an update, I did find the #6 control arm bolt, (#7 & #8) to be a tiny bit loose. But not substantially. MAYBE the big bump would be harsh enough to jolt the eccentric bolt loose-ish. More pictures to come.
