The PowerStop Z17 Semi-Coated Rotor Brake Kit for 2017–2018 Mazda 3 supplies rotors, Z17 Evolution Plus low-dust ceramic pads and stainless-steel hardware for a full front-and-rear replacement. Semi-coated rotors are dynamically balanced and receive targeted silver epoxy protection on hat, outer edge and vanes to slow corrosion; the ceramic pads were validated for low dust in on-vehicle testing and include noise-reducing shims.
