The following pictures are of Richard Belliveau's 1966 Corvette with our 12.90" Scallop Rotor Kit for street application. These rotors were specially designed for street application. They are directional and balanced, do not confuse our scallop rotors with other cheaper racer verison. These are made from 32 vain directional cores, CnC machined and balance. Each rotor is custom made for the specific application. We have custom rotors in 11.75, 12.19, 12.90 and 14.0 inch with widths of 0.810, 1.25 and 1.38. Email us for additional information.
