Don't know about the jeep coils..
But, according to the width of the tires you get, and the offset of the wheels, I doubt you will get the tires to not rub without either fender trimming or a body lift.

I have 31x11.50's on mine, with a 2-2 1/2 " suspension lift, and LOTS of trimming, mostly in the front.. I have a small backspace, so I had to pound the floorboards back quite a bit.. I hate body lifts, but that would have solved most of my clearance issues..
Go ahead and trim it.. it's not that bad!! LOL
