Question on camber and fitment

Let's all chime in please

I test fitted some rims today.
and wondering if they will fit when I'm fully dumped 
with camber arms?
Rims are 20x11 -6 rear
I'm on coils in the pic.
waiting on air kit and camber arms.
my car sits like the entire car pics.black g37 is what rims where on.
I want an agressive look.like g37 in pic.not just tucked in wells
hope someone can help me out.if not -6 what would be a better offset.

I assume you've rolled the fenders.   What is the current degree of camber in the pictures?

Zero camber.it's at stock.just lowered on coilovers.waiting on camber arms.
need to know.so if I decide to sell them or refinish them and order so.e new tires.

Took coilover off today to see how it would fit with rims bagged .airred out.so no camber arms or pull or roll.looks like it's a go..
now you send rims to get refinished and air install.
