The rear camber is adjusted by the inner eccentric bolt on the lower control/swing arm. You loosen the nut and rotate the bolt to get your desired camber setting then retighten the nut while holding the bolt in place. Theres a limited range of adjustment and once the bolt is rotated too far it'll start going back the other way.
Torque spec for this is 122ft-lb and takes a 21mm socket.

In step 6-9 you can see which bolt I'm referring to, it's the inner one that connects the arm to the subframe
