Depending on the tires you're running and the look you're going for, you could probably even put a 10-12mm spacer on those wheels and still be OK. I'm running Style 22's (17x7.5; ET41) and they look like this:
According to the wheel calculator, a 17x7; ET47 will have about 12mm more inset on the outer edge than the wheels in my picture. The inner edge (clearance between struts/shocks) is the same. Neither fronts nor rears rub on mine, but the rears have a bit of negative camber (lowered; no camber kit installed).
