Front Rotor Adapter

The WILWOOD Front Rotor Adapter (WIL300-3307) is a precision brake system component engineered for law enforcement and tactical vehicle operators who demand reliability under extreme duty cycles. This aluminum adapter bridges incompatible rotor bolt patterns, allowing seamless integration of modern brake rotors onto legacy or custom brake platforms. Whether you're upgrading a patrol vehicle, armored platform, or high-performance tactical rig, this adapter ensures your braking system matches your operational requirements without costly frame modifications.

Manufactured from aluminum in natural finish, the Front Rotor Adapter converts a 5 x 3.880-inch bolt pattern to a 6 x 6.250-inch rotor bolt pattern, enabling cross-compatibility between different brake manufacturers and generations. The adapter's lightweight construction—just 0.86 pounds—minimizes unsprung mass, preserving vehicle handling and reducing brake fade during sustained heavy braking. Each unit is precision-machined to WILWOOD's exacting tolerances, ensuring zero runout and consistent pad contact that translates directly to stopping power you can trust in critical situations.

This adapter is ideal for mechanics and fleet managers standardizing brake components across mixed vehicle inventories, particularly in departments running both older and modern platforms. Installation is straightforward: bolt the adapter to your existing caliper bracket using the 5 x 3.880-inch holes, then mount your six-bolt rotor to the 6 x 6.250-inch pattern on the adapter face. WILWOOD's reputation for thermal stability and durability ensures this component will withstand repeated hard stops, high-speed pursuit scenarios, and extreme ambient conditions without degradation or safety compromise.
