Rotor 8bt .810 11.75 x 7in UltraLite

The Rotor 8bt .810 11.75 x 7in UltraLite by Wilwood is a premium brake rotor engineered for high-performance street and track vehicles where weight reduction and thermal management are critical priorities. This ultralight disc rotor is built for enthusiasts and professional mechanics who demand superior stopping power without the penalty of unsprung mass that compromises handling, acceleration, and suspension geometry.

Wilwood's UltraLite construction utilizes optimized rotor geometry and advanced casting techniques to achieve a lightweight design while maintaining the .810-inch rotor thickness required for adequate heat dissipation during sustained high-temperature braking events. The 8bt designation indicates an eight-bolt mounting pattern, offering compatibility with Wilwood's modular brake system ecosystem and allowing seamless integration into custom and factory-based applications.

At 8.43 pounds per rotor, the weight savings translate directly into reduced rotational inertia—critical for vehicles where every fraction of a pound impacts acceleration, braking response, and corner exit velocity. The 11.75-inch outer diameter provides ample swept area for consistent heat absorption and performance, making it an ideal choice for those upgrading their braking systems.
