Not going to happen unless just one side rubs from the axle not being properly centered via the correct length track bar.
Are your axles well centered or are they off to the side?
As I said earlier I am running 4" of backspacing which positions my tires closer to the spring perches than yours are. Mine do not rub.
Jerry, my problem with the wheels I have is that the rear ones come in contact with the brake calipers without the spacers. I am running the G2 Brake Disc Conversion on the rear and their calipers sit closer to the rims than the OEM ones up front. I could get away without the spacers up front. I am confident that my axles are centered.
