The Stoptech Rear Cross Drilled Rotors are 1-piece, drilled, direct replacement rotors for factory brake systems. They feature a black e-coating on the hat, cooling vanes, and outer edge. The friction surface is double disc ground, taper-free, and non-directional. These rotors are mill balanced, include center-split core castings, and utilize Power Alloy metallurgy with directional vanes for improved cooling.
