Wilwood ULS-32 scalloped iron rotor, 12.19 x .810 in with an 8 on 7.00 in bolt pattern, is designed to reduce rotating weight while managing heat for competition use. These rotors provide a balance of lower mass and thermal stability for sprints, late models, and modified classes that race under low to medium sustained temperatures, improving braking consistency and service life.
