My rear wheels are 9.5" wide(total rim width is 10", with a 275/40-18 tire mounted the total width is 11").
I will need to test fit the 18's with the tires mounted because the distance from the inner wheelhousing to the inner edge of the quarter lip is 12 1/8".
I think with a precisely measured spacer the wheels will fit as long as the lips are rolled. When I refer to "spacers" I am not inending on using a five holed washer, but a machined spacer basically just like the adapters, but with the same pattern from hub to wheel.
The 17" front wheels are are only 8.5" wide, and really should be no problem at all.
I will have to do some shoe-horning, but I know it can be done.
