I've found all different sizes and styles of Dog Dish hub caps. The ones I really like are from the Kaiser Willys web site. They are 10.5" Overland Willys hub caps that require clips. I don't know if they will fit the stock spare wheel, though. US Steel wheels makes a smoothie Rat Rod steel...
I'm keeping my Sport S stock except for larger tires after the originals wear out, maybe 33" or 34" Nitto Ridge Grapplers. I had a JK with a Daystar spacer kit and did not like the results, excessive bump steer. The only limitations are not being able to bump, dent and scrape up my brand new truck.
Factory optional Slush Mats are too smooth. After the water and slush freezes on them they become a skating rink. After market mats would be a better choice.
