USRT's 334mm slotted-only rotors are zinc coated for long-term durability. Slots constantly skim/level both brake pad surface for maximum coverage, gripping, and stopping power. They also vent pad material gasses that would otherwise push the pads away. Performance loss is avoided.
These are premium parts. Black ZINC plating lasts far longer than inferior but common black oxide coating. Coloring on contact surface is worn away within about 10 miles. All the rest lasts the lifetime of the part, keeping it beauful and "ready to fight".
As direct bolt ons, these rotors are superb candidates for swap projects.
