My setup will only rub a little when backing out of a steep driveway at an angle. Here are the specs:
-18x8.5 ET44 front with 225/40/18 tires, 15mm spacers
-18x9.5 ET46 rear with 255/35/18 tires, 15mm spacers
-Eibach Sport Springs with #2 pads up front, #1 rear

The overall wheel+tire diameter of your setup is a bit larger than my setup, but since Eibachs drop around 1.5", your setup might not rub with proper offset and spring/shock absorber combination. If you lower your car 1" and the wheel arches still come too close to your wheels, you can fine tune your ride height using thicker spring pads.
