    Wilwood's Drilled Steel brake rotors provide a durable lightweight option in applications where sustained temperatures remain in the low to moderate range, and high heat spikes are only observed on an intermittent basis. Steel brake rotors are typically found in lighter weight open wheel cars such as sprints and modifieds. A special alloy and proprietary manufacturing processes give these rotors high resistance to thermal distortion with excellent friction and wear characteristics against the pads.

    When it comes to brake 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. Wilwood's ULS-32 scalloped iron rotors provides effective lightweight options for sprints, late models, modifieds, and other competition applications that race in low to medium temperature ranges.

    Note: Suitable for Light Dirt Racing applications. Scalloped Brake Rotors are unsafe for street use.

    • Scallop configuration provides greatest weight reduction on a vented straight vane iron rotor
    • Scallop machining removes as much as three pounds, or nearly 33% of the rotor mass
    • Vented castings provide increased cooling capacity over machined steel plate rotors
    • Improved structural durability over drilled rotor designs
    • Thread: Thru

    • Vented castings provide increased cooling capacity over machined steel plate rotors
    • Improved structural durability over drilled rotor designs
    • Vented iron
    • Inboard mounted
    • Threads:  Thru

    Note: Suitable for Light Dirt Racing applications. Scalloped Brake Rotors are unsafe for street use.

    Steel rotors have applications in all types of motorsports. Steel rotors provide a durable lightweight option in applications where sustained temperatures remain in the low to moderate range, and high heat spikes are only observed on an intermittent basis. This could be anything from a hard stopping drag race car at the end of a quarter mile, or a high speed stock car coming in from a qualifier at a super speedway. Steel rotors can also be found in lighter weight open wheel cars such as sprints and modifieds, and a variety of light weight, open wheel road course racers. A special alloy and proprietary manufacturing processes give these rotors high resistance to thermal distortion with excellent friction and wear characteristics against the pads.

    • Durable lightweight drilled steel
    • 10-3/4" diameter
    • .35" thick
    • Sprint and modifieds applications
    • High resistance to thermal distortion
    • Excellent friction and wear characteristics against the pads

    When it comes to brake 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. Wilwood's ULS-32 scalloped iron rotors provides effective lightweight options for sprints, late models, modifieds, and other competition applications that race in low to medium temperature ranges.

    Note: Suitable for Light Dirt Racing applications. Scalloped Rotors are unsafe for street use.

                These rotors are most often directly mounted to "fixed" mount hats or mounting plates, but they can also be used with special dynamic mount hats or plates that require the use of a standard hole mount disc. Each rotor size is available in the standard solid plate style, or weight drilled for lighter duty applications.
