Z23 carbon-fiber ceramic friction runs against 320mm x 24mm Evolution rotors finished in Genuine GEOMET 360 coating, applied inside the vanes as well as across the faces so the disc resists rust behind open wheels. The low dust pad compound was validated through third party on-vehicle testing in Los Angeles city traffic, and dual-layer rubberized shims damp the squeal that often follows a pad change. Rotors are 100% mill balanced and built to original equipment specifications for weight and vane count. Premium stainless-steel hardware, high-temperature ceramic lubricant and a wear sensor wire ship in the box, so the rear axle is rebuilt in one sitting.
