Does anyone know the factory max/min alignment settings on the G37 (all models for anyone else that needs this info) for camber/caster/toe that can be possibly adjusted to?

I have a 2008 G37S coupe
I'm using BC coilovers on 20" Vossens with 275 wide rear tires. Rear tires rub over bumps and I'm satisfied with my ride height so I don't want to raise it up. I'm wondering how much more negative I can have the rear camber adjusted to. Also, would adjusting the BC coilovers help avoid rubbing? How can I do this and what needs to be adjusted?

Thanks in advance.

Are these alignment specs according to oem wheels and/or how factory prefers them to be?
Or are they the actual max/min you can adjust the camber/toe/caster to? I think I remember my rears being cambered to approx -2.8 on both sides... But according to this chart in the manual its only within 1 or 2 degrees... Unless I've misread it. Can someone enlighten me?

 

Facotry specs are recommend min/max values to keep tires from shredding.
