Wilwood Superlite Drilled Brake Rotor 12.00 Inch x .35 Inch 8 on 7 ThruDrilled Rotors Application Chart

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(GIF)

Ultralite 32 straight vane brake rotors provide an excellent balance of efficient cooling and lower rotating mass on hard braking dirt tracks or rear axle service on pavement cars. UL rotors are cast from premium grade long grain carbon iron for long wear high thermal stability and resistance to distortion.Offers added performance and smoother operationusing precision turned faces with less than .001" variation in flatness parallelism or run-out.Thickness: .81" Outside diameter: 12.19"# Holes: 8Bolt Circle: 7.62"Thread: 5/16"-24Weight: 8.7 lbs32 VanesUltralite Rotor Application Chart(GIF)

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 ULD-32 drilled iron rotors provides effective lightweight options for sprints late models modifieds and other competition applications that race in low to medium temperature ranges.Cast ...

Wilwood's Drilled Steel brake 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. Steel brake rotorsare typicallyfound in lighter weight open wheel cars such as sprints and modifieds. A special alloy and proprietary manufacturing processes give these rotors high resistance to thermal distortion with excellent friction and wear characteristics against the pads.Steel Front Rotor Application Chart
