Our Performance Rotors have a corrosion-protection finish that is Zinc plated. The Zinc Coating process is an extensive hand applied operation that is not sprayed onto the rotor like inferior coatings. Each Performance Brake Rotor is immersed in different solution tanks during the coating process. The final result is a thick, protective coating that will help prevent rusting, and give you a great custom look.  However, due to certain castings, the Zinc coating may not adhere to small areas of some rotors.

When you receive your rotors, they will be completely Black or Silver. As soon as you install them and start braking, the friction from the pads will strip the zinc from the pad surface, turning it Silver and leaving the holes, slots, and the rest of the rotor zinc coated in the color you selected. (See before and after photos below) The zinc coating that is removed from the pad surface quickly dissipates, and will not gum up the pad surface or affect the braking performance of the vehicle.
