You should roll your fenders, and of course, to run that camber, you need some adjustable front upper control arms

REARS: 20x11 +0 fits with -2 camber with 285/30. Your size (20x11.5+15) 9mm less, so you should be more than fine with -2 camber. Stock is around -1.8. Given that you are aiming to go pretty low (top of tire to fender), I suspect you'll need adjustable arms to correct toe, even tho camber can be achieved with stock components

Something like a 245/35/20 F and 285/30/20 rear would be in the ballpark
