Rotor Bolt Circle(s): 3 x 5.00
Material: Aluminum

Aluminum Sprint / Midget Rotor-3H Description

Wilwoods 3 hole mount rotors are precision CNC machined from high strength billet plate. Full symmetrical machining provides perfect balance, perfect flatness and the truest rotation of any rotor being built. These rotors fit the popular 3 x 5.00" mount bolt circle found on most sprint and midget front hubs. Wilwoods engineered drill slot pattern combines the highest degree of weight reduction with the highest resistance to thermal distortion in the contact faces. You get smooth engagement and a consistent full pedal from the low knock-back characteristics of this design. A durable black anodized finish prevents corrosion and simplifies the visual inspection of the contact faces. The best results are always achieved using PolyMatrix Q compound brake pads with these rotors.

Rotor Bolt Circle(s): 8 x 7.00
Material: Steel

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.
