Wilwood scalloped steel rotors are precision-machined from a special alloy to resist thermal distortion and offer consistent friction and pad wear for sprint and midget racing. Proprietary manufacturing improves heat resistance for applications with mostly moderate sustained temperatures and intermittent spikes. These rotors are formatted to fit the popular 3 x 5.00-inch mounting bolt circle used on sprint and midget front hubs.
