Rotors in this kit measure 320.3mm and carry a zinc plating rather than the full GEOMET coating used on PowerStop's CRK series, so the surface finish and the part number differ even though the friction package is the same Z23 specification. Cross-drilling vents heat and gas out of the pad face while the slots wipe away debris, and the carbon-fiber ceramic compound tested about 30% below OE for brake dust in third-party on-vehicle work. One rear brake pad wear sensor wire is packed with the kit. Dual-layer rubberized shims, premium stainless-steel hardware and high-temperature ceramic lubricant round out the box.
