Yes, in rare instances brake rotor manufacturers forgo the use of cast iron for the sake of achieving specific performance objectives that the traditional metal simply cannot support. A prime example of this are the carbon-ceramic rotors fitted to many exotic sports cars. Another example are the discs manufactured from ‘discalloy’ which is typically protected by a “thermic black” coating that wards off corrosion for the life of the part. With such a wide range of rotors to choose from, consumers have a great opportunity to customize their vehicle when replacing the discs – whether it be aesthetically or functionally. By carefully selecting the best brake rotors for their particular application car owners can improve both the braking performance and appearance of their vehicles.
