These rotors feature a fully machined scallop configuration that provides the highest degree of weight reduction on a vented straight vane iron rotor. Wilwood's scalloped machining will recover as much as three pounds, or nearly 33% of the rotor mass. The vented castings provide increased cooling capacity over machined steel plated rotors, with improved structural durability over drilled rotor designs. This rotor measures 11.75" in diameter.
