I have 15 inch Pacer rims on my WJ with 3.5 backspacing and they do fit both types of brake calipers(teves and akebono) I did have to move my lead weights out of the way.(closer to the face of the rim in the same location)
Some folks dont like the wheels sticking out this far but I am ok with it.....
