Solid one-piece cast-iron rear rotors measuring 259mm in diameter at a 9mm nominal thickness, 100% mill balanced and left uncoated in a natural finish. Because a hybrid rear axle sees light friction duty and long service intervals, the Z17 ceramic compound is chosen for low dust and quiet cold engagement rather than high-temperature bite. Dual-layer rubberized shims back the pads as a noise insulator. Premium stainless-steel hardware and hi-temp brake lubricant complete the axle set.
