Sorry, I got so "wordy" I realize I failed to make my question clear. What I need is the offset and/or back-spacing for the 18X11 wheels.

I have 17X10's with 275/40's all around now. The fronts fit fine. The offset is perfect as the wheel/tire fills the wheel arch opening nicely. However; in the rear, the same tire/wheel is consumed by the wheel well opening. The tire is easily 1.5" inset, and it looks like the combo is way too small for the car. It looks ridiculous. So since I currently only have one set of wheels for the car, I figured I'd get two sets of wheels for the rear. 17X10's in the front, and 18X11's for the back. I was just wondering if anybody knew the offset of the 18x11's.
