Product Description

The Wilwood 160-4766 is a high-performance drilled steel brake rotor designed for universal use in racing, drag, dirt track, and custom performance brake systems. Its 12.90" diameter and solid steel construction provide strength and durability, while the cross-drilled surface improves airflow and heat dissipation under heavy braking. The dynamic mount design reduces thermal stress at the hub, allowing controlled expansion during intense braking conditions.

Precision machining ensures flatness and consistent thickness for smooth performance and reduced vibration. The black electro-coat finish provides corrosion resistance and long-term durability. This universal rotor is ideal for builders and racers who require reliable, high-performance braking without being tied to a specific vehicle make or model. Its configuration allows compatibility with a wide range of performance calipers and adapter systems.
