Have knowledge in Alignment/Camber adjustment?

[TMAN1985]

I got my car lowered on Swift Spec R Springs. I had my alignment right after with stock camber arms. My camber was -2.3 in the front and -3.3 in the rear. The max to be in spec is -2.2 all around and -0.5 is stock (according to the place that I went). I ordered Camber arms for the rear and installed them. It was apparently suppose to go 2 degrees either way from stock camber meaning my rear should be at -1.3? Anyways, when they did the alignment they said they couldnt adjust the camber much because the toe would be way off. So they made it go from -3.3 to -2.7. Does this sound right...were any of you able to go with less negative camber?
