The Wilwood Ultralite 30 Brake Rotor, part number 160-3747, is designed for high-performance braking applications that require dependable stopping power and reduced rotating weight. This iron rotor features a natural finish and is engineered for use with compatible Wilwood brake systems and hardware. Its six-lug mounting pattern supports applications using a 5.5-inch bolt circle, making it a practical replacement or upgrade for select performance, racing, and specialty vehicles.
The 10.25-inch outside diameter and 0.75-inch thickness provide a balanced combination of braking capacity, stiffness, and efficient heat management.

The natural iron surface is suitable for applications where performance and function are prioritized, and the rotor should be installed according to the vehicle and brake system manufacturer’s procedures.
