Fontana Nissan Racing has developed a new racing front rotor for the GT-R. The new rotor is custom made for Fontana Nissan Racing by one of the top racing rotor manufactures. This new rotor addresses the issues we found racing the Fontana Nissan GT-R in Redline Time Attack. The new rotor features a heavy duty directional vane design yet is 1.5 pounds lighter than the OEM rotor. The new rotor is designed to be mounted on the OEM hats. It is heat treated, balanced, and features gas slots. We have eliminated the crack promoting through holes that have plagued the OEM design.
