Product Description

The Wilwood 160-0277 UL32 vented rotor is engineered for high-performance braking applications requiring a balance of lightweight construction, durability, and effective heat management. Featuring a straight vane 32-vane internal design, this rotor delivers reliable cooling performance across a wide range of driving conditions, from street performance to motorsports environments.

Constructed from premium long-grain carbon iron, the rotor provides excellent resistance to thermal distortion and wear under repeated braking cycles. Its non-directional vane design allows for flexible installation on either side of the vehicle, making it ideal for custom builds and Wilwood brake kit applications. Designed as a universal rotor, it must be paired with the correct hat and mounting hardware for proper fitment and optimal braking performance.
