I have 19 x 9 ET52 all around on mine. 235/35/19 (so the same amount of stretch you would have) Spaced 10mm on the front and 20mm on the back so ET42 front and ET32 rear. -2.5 degree of camber on the rear.
I'm on air, but it doesn't rub on my drive height, which is pretty low. Lower than 50mm anyway.
I did bend my arch though, turing the wheel when I was too low. Nothing to do with the wheels though really.
When my front tyres expire I'll be going down at least one tyre size so they can turn more easily.
