It doesn't matter how far your bushing is pressed on. The control arm's hard point for forward-back isn't going to ever be a friction based rubber-metal bushing. It's the center balljoint which is nicely bolted through the subframe.

The only caster adjustment upfront is how eccentric the bushing is. And, as you can tell with normal (Not 95 M3) control arm bushings... the whole is in the center. Aka non adjustable caster.
And without getting a alignment, you don't know whats going on period. I know you don't wanna hear it, but don't complain about an issue if you don't wanna pay to get it fixed. An alignment is cheaper then buying your own alignment rack.

Photos aren't really what's important here. We all know that you can't adjust the placement of the control arm bushing on the control arm. The bushing lollipops anchor to the chassis in a fixed location, and the control arms themselves are anchored in a fixed location by the ball-joints which are bolted to the sub-frame. You can't move the either the control arm or the bushing fore or aft, since they were not designed by BMW to be adjustable in any way. As mentioned in an earlier post, the only variable is how far into the lollipop you pressed the bushing. But even then, it's probably only going to vary by a matter of millimeters, which won't have a perceptible effect on handling. And there is no "orientation" for the non-M control arm bushings, since they are centered.

Basically we have a car here which has had what sounds like one of two control arms replaced (they should be replaced in pairs), both FCABs relaced, and (I think...) no alignment performed afterward. That is a perfect recipe for wonky handling. And then of course there is the possibility of other unrelated/coincidental factors. But if you removed centered FCABs from the car and then installed new centered FCABs, the bushings are not what is causing whatever symptoms you are experiencing.

If this car really has not been aligned after the work was performed, do that first before wasting any more time trying to figure out what's going on. Trying to troubleshoot a misaligned car is pointless.
