While I can't comment on whether you can get away without using wheel spacers on your specific vehicle with your specific tire set-up, I just wanted to provide links for how to go about piecing together the kit I did! Your mileage may vary, and the availability of a WK2 specific wheel spacer kit may someday exist, but for now these are the parts required to use a United States made AlloyUSA spacers.
DO NOT SKIMP OUT ON WHEEL SPACERS - THEY CAN KILL YOU. I have run AlloyUSA products on both my Wrangler and now Trailhawk for a combined decade between the two. I highly suggest them for both their products and customer support.
