Rotor 6bt .810in 11in x 6.25in Ultralite

The Rotor 6bt .810in 11in x 6.25in Ultralite by WILWOOD represents a purpose-built brake rotor engineered for high-performance tactical and law enforcement applications where weight reduction and thermal management are non-negotiable. Developed with input from active duty operators and armored vehicle specialists, this ultralite rotor delivers the stopping power required in critical situations while minimizing unsprung mass—a specification that directly improves vehicle handling, acceleration, and fuel efficiency in duty vehicles operating under sustained hard braking cycles.

At 7.78 pounds, the Rotor 6bt achieves its ultralite designation through advanced material engineering and precision manufacturing that maintains structural integrity under extreme thermal stress. The .810-inch thickness and 11-inch x 6.25-inch face dimensions are optimized for standard heavy-duty brake caliper mounts, ensuring compatibility with existing fleet hardware while delivering superior heat dissipation during sustained stops. WILWOOD's design balances reduced rotational inertia with adequate thermal mass to prevent fade during repeated hard stops—critical in tactical operations where brake performance degradation can compromise officer and team safety.

This rotor benefits patrol vehicles, tactical transport platforms, and armored units that require proven stopping performance without the penalty of excessive weight. Installation is straightforward on vehicles already equipped with compatible six-bolt hub assemblies; no modifications to existing brake lines, calipers, or suspension geometry are required. Field operators and fleet maintenance teams can expect extended rotor life and improved brake response compared to OEM rotors, particularly in stop-and-go urban operations or sustained mountain driving where thermal cycling is severe.
