I'm on 17x8" with a +37mm offset with 215/45/17 tires and not rubbing. Going with a 215 wide tire does have a very mild stretch on an 8" wide wheel, but nothing ridiculous.
I can imagine that it would probably rub in the rear because it's the nature of the car to have the rear wheels stick out further than the front... So to be safe I got camber kits; front and rear. Got the rears to prevent the rear from rubbing as I didn't want to do any fender work and I got the fronts because for some reason the car seems to have positive camber and I really didn't like the way it looked.
