Wilwood's C/SiC rotors are made form a proprietary blend ceramic matrix composite material commonly known as Carbon-Ceramic. C/SiC rotors offer higher thermal conductivity and heat capacity in excess of conventional iron or titanium rotors of similar or even greater weight. Developed to withstand extreme temperatures with the highest possible degree of resistance against distortion, warping, cracking, and wear. The formulation for this composite is a derivative of technology and materials that were significant in the development of the extreme duty military spec rotors that are manufactured by Wilwood.
