I got about 18.5" fender to center when I measured recently, so that's about 0.75" below stock. (I add 1.5" to the diameter of the wheel to get the outside edge of the rim.)

Are you on lowering springs or bags? The measurement is suppose to be from the bottom of the rim to the upper fender flare by keeping the tape measure perpendicular in alignment of the center BMW hub cap. That's what that document was I posted a couple posts back.

Okay...so I took out the RH side wishbone out, and the ball joint doesn't feel AS loose. One way I can tell is that the ball joint has enough internal friction that it will stay in one place while the LH side ball joint has nearly none and the rubber seal returns it to center.

My guess is that the LH side is bad of course.

Either way...I order Lemfoerder branded ones from FCP Euro. I pray to J these will get me to toe in--but TBH, I have very little confidence just because of a little play in the ball joint.

If you look at the bushing end of that wishbone, it should be perfectly centered in its hole. In the E53's I've had done, the bushing was deflected noticeably inward, which would translate to the top of the tire moving inward.

Yours looks to be deflected inwards as well.

Compare the bushing end of your incoming LMI wishbone with the ones you removed.

UPDATE.
Well this is frustrating. I waited nearly two weeks to get the wishbone control arms and made sure to order the top of the line OEM, Lemfoerder. Lo and behold, something doesn't fit correctly. The brake-line holder will not install correctly because the weld extended just a TINY bit too much. Of course it has to be the weld. I already just tried drilling out the weld--but already broke a bit. Buying a new brake-line holder will most likely yield the same results of the bolt not going through due to the extended, excess weld.

ERGH!!! Top brand MY A$$!

Stock 3.0i. I generally measure to the center of the roundel. It's the best way to measure for easy comparison since it's not impacted by wheel diameter.

That sounds like stock height, but the 1/2" difference is odd.

I've measured half inch differences on brand new BMWs. I wouldn't worry about that.

So the rubber seal is possibly masking this movement? I guess that makes sense. I guess this REIN wishbone is a REAL piece of junk...

Oh gotcha.

Yeah...i'm not too sure why there is a 1/2" difference between the two. I remember one of the rubber isolators on the springs was slightly deteriorated, but nothing else. I guess to be super technical I would need to weigh the vehicle at each wheel the same time to determine if there is a substantial weight difference causing this.
