PowerStop's Z23 Evolution rear brake kit pairs two cast iron rotors with one axle set of Z23 carbon-fiber ceramic pads. The rotors are plain faced rather than drilled or slotted, and carry genuine Geomet coating inside and out, so the exposed surfaces resist rust instead of streaking the wheels. The Z23 carbon-fiber ceramic compound raises bite over a standard ceramic pad while keeping dust low and wheels cleaner.
