• Designed for 1955–57 Chevy Spindles: Engineered specifically for use with Speedway Motors 2-inch drop spindles (part #91034921) for proper fit and performance., • High-Quality Vented Rotors: Includes 10.5-inch GM vented brake rotors that deliver strong, consistent stopping power with reduced fade under heavy braking., • GM Metric Caliper Setup: Features 1978–1988 GM metric single-piston calipers, along with matched pads and slide bolts for a complete, ready-to-assemble system.
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. Suitable applications: Dirt Sprint / Midget Racing. Not for street use.
6 on 5.5" mount, 10.5" O.D, .75" thick.
Rotor has a 10.5" diameter and has a scalloped design, Kit is specifically designed to increase braking torque and thermal performance of the GP320 4 piston calipers, Mounts are included for standard Sprint spindle to match the included 10.50 x 0.19” Super Alloy rotor, Also comes with Composition Metallic brake pads, lightweight aluminum dynamic mount 3-pin rotor adapter and T-nut hardware kit.
These rotors are specifically designed for the 1979 and Up GM applications, They come with wheel studs installed and have a 5 on 5", Also drilled for 5 on 4.75" bolt pattern, Bearing spacer allows your front hubs to be tight with minimal drag and side pre-load, Bearing Kit for GM #2 Metric Front (Set 3/6); DRP Premium Finished. (1) LM67048, (1) M12649.
This lightweight hybrid rotor is for use with 1979 and up Metric spindles, 5/8"-11 coarse thread studs come installed in the 5 on 5" bolt pattern, Compatible with 3 piece spindles, Premium cast iron vented rotor design is perfect for dirt circle track racing, Not for use on asphalt circle track cars due to the high load and stress of that application - we suggest billet hubs for asphalt racing.
We stock those hard-to-find replacement brake rotors for your '79-'81 GM "midsize" cars, New steel/iron rotors should be bedded in before being used in racing conditions, Proper bedding will prepare the rotor surface, prolong the rotor's life, and make it more resistant to thermal checking or cracking, Features a cast Iron construction for long lasting life, Bolt pattern is 5 on 4.75".
Designed for Dirt Sprint car Inboard Use, Rotor has a diameter measuring 10.5" and has a rotor hat pattern of 6 x 5.50", These are one of Sprint racing's lightest .810" rotor at a weight of only 3.20 pounds, A drilled, slotted, and scalloped design with 24 cooling vanes provides excellent high temperature stability, The proprietary Super Alloy Steel greatly enhances the durability and lifespan of this rotor over comparable lightweight steel or iron rotors.
