Never really fooled around with camber, but who does it? Can you get the alignment shop to add camber or do you guys mess with it yourself?

I ask because i currently have 18x8 +31F and + 27 rear and rubbed a little both front and backs with stock camber.

Got a new set of wheels coming in

and the offest is going to be +25F and +15 or +20 in the rear depending on if I use a spacer or not and know I will be rubbing.
