Drilled Steel Rotor Description

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.
NOTE & CAUTIONS:
Suitable applications: Drag / Dirt racing

Super Alloy Slotted Rotor Description

Super Alloy treated titanium rotors show improved toughness, increased life, better low-temperature friction, and less high-temperature creep and distortion on wing and non-wing 410 Sprint cars. Wilwood titanium slotted rotors are Sprint racing's longest-wearing lightweight rotors at less than 3 pounds. This 10.20” rotor fits the 3 x 5.00” mount bolt circle for Sprint Car and Midget front hubs.

Wilwood's proprietary treated Super Alloy titanium dramatically enhances this rotor's durability and lifespan over comparable lightweight rotors. Less unsprung weight and rotating mass improves acceleration and handling. The improved slotted surface design allows for fuller pad contact and is engineered for excellent high-temperature stability, with consistent performance and pedal feel.

  • Slot design promotes even heat dissipation and improved wear
  • Treated Super Alloy titanium has less distortion and dramatically increased life
  • Fine micro-finish beds in new pads quickly for optimal friction and wear

NOTE & CAUTIONS:
Only for dirt Sprint Car and Midget left front use.

Aluminum Sprint / Midget Rotor-3H Description

Wilwood's New Type III hard-anodized aluminum rotor finish improves performance and increases life over all other aluminum rotors. Precision CNC machined from high strength billet, full symmetrical machining provides perfect balance, flatness, and the truest rotation of any rotor made. This 10.20” rotor fits the 3 x 5.00" mount bolt circle for Sprint Car and Midget front hubs.

Wilwood's specifically engineered drilled pattern for each rotor, along with Type III hard-anodized aluminum, combines the greatest weight reduction with the highest resistance to thermal distortion. This design's low knock-back characteristics give lap after lap of smooth engagement and a consistent full pedal. For best results, use PolyMatrix Q compound brake pads with these rotors.

  • Hard-anodized for greater friction and longer life than other aluminum rotors
  • Lowest thermal distortion and run-out of any aluminum rotors
  • Withstands higher heat than competitor’s aluminum rotors

NOTE & CAUTIONS:
Specialized product for certain applications. Unsafe for street use and many types of racing.
