AFCO's disc brake rotors set the pace for design, quality and performance. Specially engineered materials, computer-enhanced design, and extensive lab and track testing have yielded a superior brake rotor. All AFCO rotors have been optimized for strength, weight, and heat dissipation ability to meet the demands of the serious racer. Premium grade alloy for superb thermal shock stability Machined and blanchard ground to assure precise flatness Precise vane placement for high volume cooling Bolt Circle: 7" Diameter: 11.75" Mount: 8 x 5/16" Weight: 10.2 lbs Instructions (PDF)
Every Wilwood brake rotor is cast from premium grade, long grain carbon iron. This material exhibits long wear, high thermal stability, and excellent resistance to distortion in high heat. Modern foundry and machining techniques hold close tolerances on face and vane thickness. Combining the correct face thickness with a 32 vane casting provides superior heat management and long service life with low rotating and unsprung weight. The straight vane design also makes it possible to use the same rotor on left or right hand mounting locations. Ultralite Rotor Application Chart ...

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 ...

AFCO continues the commitment to bring new and innovative components to the racing community. Pillar vane rotors are engineered to provide superior strength, reduce rotor weight and run cooler. At the heart of the rotor, each pillar is diamond shaped providing brake pad surface stability as well as reducing rotating weight over rotors of similar strength. Racers will take note of reduced weight when compared to rotors of similar strength. Reduced rotating weight means reduced lap times. When brake performance is discussed, AFCO is the bottom line.
