Painted calipers actually refers to the PP 20" daisy wheel setup, not actually calipers that are painted. Just like brake rotor sizing on the Edge refers to 18" rotors when it actually means what came with 18" wheels.
Pads are different between PP and non-PP setups, as PP is more track-oriented than non-PP from the factory. BUT whether the caliper differences (x-drilled piston, orange seals) from 2013 MY still apply, IDK.
