Ultralite 32 Vane Scalloped Rotor

When it comes to rotors, racers are constantly searching for the ultimate balance between the lowest weight and the ability to effectively manage heat. Decreased rotating weight in the drive line provides quicker deceleration under braking and quicker acceleration out of the corners. Lower weight also benefits handling with improved spring and shock control over the unsprung suspension mass. Two options are available: Wilwood's 160-8343 Ultra Light Weight ULS-32 scalloped iron rotor provides effective lightweight options for sprints, late models, modifieds, and other competition applications that race in low to medium temperature ranges. Weighing in at 5.3 Lbs., it is the lightest scalloped iron rotor around or the medium weight option 160-8814 at 6.45 lbs. that gives added mass and durability.

Additional Notes

Ultra Light Weight ULS-32 Series Scalloped Rotors feature a fully machined scallop configuration that provides the highest degree of weight reduction on a vented straight vane iron rotor. Scallop machining will remove as between 2.3 to 3.5 pounds, or nearly 40% of the rotor mass. The vented castings provide increased cooling capacity over machined steel plate rotors, with improved structural durability over drilled rotor designs.
