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

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.

NOTE & CAUTIONS:
Unsafe for street use & unsuitable for most forms of Racing.

Super Alloy Drilled Rotor Description

Super Alloy Steel 10.50” x .16” Solid Rotors are one of Sprint racing's lightest rotor at a weight of only 1.40 pounds. Wilwood’s proprietary Super Alloy Steel greatly enhances the durability and lifespan of this rotor over comparable lightweight steel or aluminum rotors. A Drilled and scalloped design provides excellent high temperature stability, rapid heat dissipation, and consistent performance from the brake pads. The fine micro-finish surface beds quickly with new pads. It provides a cost effective, lightweight solution with quick response, long service life from the pads, and consistent braking at all temperatures.. Lowered rotating weight promotes quick acceleration, deceleration, and improved handling.

SRP Drilled Performance Rotor

SRP Drilled Performance Rotor Drawing

SRP Drilled Performance Rotor Description

SRP Drilled Performance Rotors feature a specially engineered directional cross drill and face slot pattern that improve brake response and pad performance throughout the entire range of light to heavy braking. The venting and cleaning action of the holes and slots will reduce pad glaze and disperse gasses and heat generated during the pad to rotor interface. The holes and slots also inhibit irregular pad compound build-up on the rotor faces resulting in smoother engagement and improved pedal response in all conditions. The material removed also contributes to lower rotating and unsprung suspension weight.

NOTE & CAUTIONS:

Ultralite 30 Vane Scalloped Rotor Description

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. 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.
