Product details
This compact dirt-racing rotor combines a scalloped steel perimeter with drilled friction faces. The 10.20-inch diameter, 0.31-inch solid section and three-hole flange create a specific lightweight racing interface rather than a general replacement disc. Founded by Bill Wood in 1977, Wilwood designs and manufactures disc brake systems in Camarillo, California. Its range includes calipers, rotors, master cylinders, valves, fittings and lines for motorsport, street performance and specialized applications. Rotor choice belongs within that complete system: the caliper, pad, mounting hardware and intended duty must work together.
