FWIW, much of the P5160051 kit appears to be sourced from RAM 1500, calipers, pads & brake lines. The 13" rotor is taken from the BR6 kit, which is either JK export or Dodge Nitro. The caliper support is specific to the kit. Haven't checked the booster & MC numbers yet. If all that stuff is included with booster & master it's a steal.
