I'll see if I still have the printouts of the alignments. IIRC the setback was as close to 0 as it could be. The measurement at 20° was not done.
I put my ass in the driver seat before making adjustments, so the computer could calculate how much of a difference there is in camber with my weight in it. I dunno how to properly explain it in English, but I think you know what I mean.
I do agree that E46 with steering rack issues are never heard of, but it all started after replacing the rack, and when someone else told me that his E46 drove 100 times better after replacing the rack, then indeed it could be that this is the issue.
What if those measurements at 20° are off? What could that be or what handling issues would that cause?
