Q: What do the black rotors look like once they are bedded-in?
A: The annulus (where the pad comes in contact with the rotor) is quickly stripped of the e-coating and appears the same as any iron rotor. The e-coating remains in the radius around the drilled holes, and in the slots providing a nice contrast and high visibility of the drilled and slotting pattern of the rotor, as well as protecting those areas from rust.
Q: Why are my rotors black, I wanted zinc?
A: Wilwood uses a process called “E-Coating” to protect our rotors from corrosion. E-coating is another name for electrocoating, electropainting, or electrophoretic lacquering. It is used to deposit a protective coating as opposed to a metal such as is deposited by electroplating. Parts are dipped into a vat of the e-coat material and are electrified in order to promote a reaction at the surface, which deposits the protective agent. Through this process, we ensure that all exposed surfaces are protected from corrosion, providing the very best in protection. You can still order Zinc plated rotors as an option, but keep in mind that the zinc coating is more expensive and offers less rust protection than e-coat.
