Product Description	ACDelco Advantage Coated Disc Brake Rotors provide reliable vehicle braking power. Their robotic-applied, baked-on coating helps prevent brake pulsation, helps prevent the rotor from seizing to the hub, and provides superior rust prevention against harsh environmental elements such as rain, snow, and corrosive road sprays. They feature a non-directional ground finish that helps to extend brake pad life and minimizes thickness variation. They are also ready to be installed right out of the box, with no machining required. These dependable aftermarket Advantage Coated Disc Brake Rotors offer quality at an economical price. ⚠<b> WARNING:</b> Cancer and Reproductive Harm - www.P65Warnings.ca.gov
