I started putting together a JK guide at one point, but I got side tracked, but yes there will be a JK file, and a WK2 file as well. I would really like to backfill out with the older models too, I started on a YJ guide at one point but also didn't finish it.
I would also like to flesh out the individual pages with high quality photos showing each variation mounted on a near stock Jeep. The idea being to give perspective from a stock viewpoint. I would then have one page for a mix match of all different stock wheels on different Jeeps, silverstars on MJs, older XJs, moabs on a MJ, JK saharas on an XJ, etc.
