I just ordered the Mopar Big Brake Kit for my '13 JKU Rubicon. I am still running the factory 17" Rubicon wheels (new style not Moabs). It's documented that the factory Moab 17" wheels will interfere with the BBK calipers on the backside of the wheel and require wheel spacers. Does anyone know if the newer style factory 17" Rubicon wheels will clear the Mopar BBK? I am trying to determine if I need to buy wheel spacers before I start the install.

Update! Finally got around to installing the kit. It does fit the factory Rubicon wheels without any modification. It's a tight fit. There's probably less than 1/16" between the caliper and stick-on weights on the inside of the wheel... Braking performance/feel is easily twice as good as the factory brakes. I don't have to put near as much pressure on the brake pedal to stop. Activating ABS on dry pavement is easy with only moderate brake pressure. The brakes now hold the Jeep with confidence on steep grades in 4:1 low. It's a must do upgrade! You don't know how much brake you are missing until you experience great brakes.
Sorry I missed your initial post I could have pulled a wheel spacer and confirmed they fit. If you want even more stopping power check out the Black Magic pads for the kit. On my 17' JKUR I'm running 35" KO2s on Rubi rims and braking is done with a toe now not the foot.
