P2DK-RPX Kits contain either front or rear RPX pads for track days and race use, along with a pair of 2-piece discs featuring our Thermic Black coating for corrosion protection on the non-swept area, available for either the front or rear kits. Designed for ultra-heavy braking applications, RPX pads deliver intense initial bite and extreme temperature stability while 2-piece rotors prevent thermal warping.
