alignment

I keep on messing around with my suspension because i started out with ground controls and i decided to change them to sprint lowering springs so I keep messing the alignment up. I've tried guessing myself to save money cause i don't want to go back to the alignment shop again and again but utimately i have to... i have camber bolts on

is there a specific way to align the rotor before i tighten the bolts with the camber bolts and how much torque do i need?

thanks
