Camber could be advised differently depending on how you plan to use the car, but you should be aiming for between 0 toe up front and 1/32-1/16" toe in at the rear. I don't know enough about the steering centering reset to say if this could be an issue. Either way, it shouldn't matter that it's a Cadillac dealership: every car they make plus the ATS is/was based on this same platform, so it should look familiar to them. Get the alignment specs and lets go from there.

So I’m familiar with the street and track alignment specs for camber, toe, caster etc. and they set it all correct on paper. I specifically asked for a before and after and they delivered that. I can’t remember the exact numbers (unfortunately they were in my glove box) but on paper they were in range and actually they were more specific than previous alignments where they just got it in range at a random number and left it. Dealership just called me and stated that the rack they used to align it was off and the alignment they performed ended up screwing up the numbers a lot. They used the second rack and performed two more alignments and stated the car is good to go. Two techs drove the vehicle and stated they got up to 80 MPH and it felt good but I will find out tomorrow morning if that’s true or not.
