PowerStop builds this front left rotor as a direct replacement for the factory disc: 369 mm across, 39 mm thick, vented full cast iron on a 170 mm bolt circle with 10 lug holes. Cross-drilled holes pull heat out of the friction surface and are chamfered so stress cracks do not start at the edges, while rounded slots wipe gas, dust and water off the face to keep the pad on clean iron. Silver zinc dichromate plating covers the hat and vanes to hold off surface rust. Every rotor is 100% mill balanced and held to tight disc thickness variation and runout limits, so it bolts on with no modification. Minimum service thickness is 37.4 mm, and no ABS tone ring is fitted.
