Wilwood 170-13539 Brake Rotor Hat with Parking Brake, 12 x 8.75 in Bolt Pattern

The Wilwood 170-13539 Brake Rotor Hat is designed for performance brake system applications requiring a durable, accurately machined mounting component. This aluminum rotor hat features a black painted finish for a clean appearance and added surface protection. It is engineered to support compatible Wilwood brake rotor and parking brake configurations while maintaining precise wheel and hub alignment.
The hat uses a 12 x 8.75-inch primary bolt pattern and accommodates wheel bolt patterns of 5 x 4.50, 4.750, and 5.00 inches. A 3.060-inch center bore supports proper positioning on compatible hubs and helps promote consistent brake system operation. The lightweight aluminum construction helps reduce unsprung weight compared with heavier steel alternatives, making it suitable for performance-oriented vehicle builds and custom brake installations.
Designed for professional installation, the Wilwood 170-13539 should be matched with the correct rotor, caliper, hub, wheel, and parking brake components before assembly. Verify all mounting patterns, clearances, and brake system specifications for your application. This brake rotor hat is supplied individually and is intended for use with compatible Wilwood components and properly configured braking systems.
