How Do I Adjust rear Camber?

[M'Kehyah]

I installed the Eibachs and need to adjust rear camber prior to bringing in to alignment shop.

Is it as easy as loosening the camber bolts and then... rotating with a box-end wrench and re-torquing?

From previous posts about alignement after the Eibach install - I need to simply "max" them out (positive camber) so no fine adjustment is needed...

Thanks!
