Dealers won't adjust outside BMW spec, but indy shops will, they just need to know the spec you want.

Mine was adjusted to spec on a hawkeye, when the shop notified me they could not get the rear right camber low enough to be within spec, I told them that's fine, get it as low as you can go and then zero out the toe in the rear so I can have less wear on the insides of the rear tires.

They knew exactly what I talked about and gave me a printout when they were done. That's why I ended up at the indy shop because I had a feeling if I went to BMW, they were going to charge me for an alignment that is done incorrectly because of a worn suspension part in the rear, then try to make me "not pay twice" for the alignment by charging me ridiculous pricing to get worn parts repaired at the dealer on the spot.

My alignment story at this local indy tire shop actually spans 2 occasions. The first time I went there, they stopped and couldn't align the car because the tie rod adjusters in the front were seized, obviously wanted to know if I wanted them to fix it for $400 bucks on the spot. I said no, I'll go home and replace them myself ($140 for both sides, free labor), and bring the X back. So I was only charged 15 bucks for an "alignment check" that day, and 2 weeks later when I brought it back I paid my normal alignment fee ($115).

Independent shops tend to be a little more flexible with stuff like that I've learned.
