Mark,
I can tell you a few things.
With 6" of backspacing the 17x11's will fit with a little hammer to the inner wheel well in back.
Then you only have to worry about hard dips in the road causing some upper wheel well rub since the tire actually protrudes from the opening. Lowering is not recommended at this point.

Not sure about the fronts though.
I can tell you if you are gonna run those 9.5" rims you need at least a 255/40/17.
9.5" rims are meant to be run with 275mm tires from the factory.

I have 315/35/17s in the rear and 17x8" in front with 235/45/17s.

You'll love the finished product.

 

This may be of some interest to you also. You may have to cut and paste it to get it to work.
