I went back to Firestone tonight, because after they installed my new tires, and did the alignment, I am experiencing squeaking noise from the rear when braking at slow speed. So, the guy took apart the rear tires, and pointed out to me that I have some rust on the inner circle of rotor. On the other hand, I asked him about if that could be caused by alginment they did, because they did align my Z back to factory spec. Now, while he was telling me how he tweaked the alignment, he said that he can only work with the toe in, because both front and rear camber are not adjustable. Ok, I'm not understanding this statement. The rear camber number is still out of the specified range from the factory spec?!! My question is, can this alignment done by Firestone affects my brake? Here are the numbers after the alignment, hope this is not too hard to read:

Camber: LF / RF / Spec
-0.82 / -1.10 / -1.33 to 0.17
Caster:
7.63 / 7.91 / 7.42 to 8.92
Toe:
0.03 / 0.04 / 0.00 to 0.10

Camber: LR / RR / Spec
-0.83 / -0.81 / -2.08 to -1.08
Toe:
0.03 / 0.03 / 0.01 to 0.09
