Adapter Rotor Lug Drive Wide 5

The WILWOOD Adapter Rotor Lug Drive Wide 5 (part number 300-16921) is a precision brake rotor adapter engineered to convert 8 x 7 inch bolt pattern rotors to Wide 5 bolt pattern applications. Manufactured from aluminum and finished in black anodized coating, this adapter delivers the mechanical compatibility needed for high-performance brake system conversions on vehicles requiring non-standard rotor pattern transitions.

At 0.38 lbs and compact dimensions of 0.75 x 0.75 x 8 inches, this single adapter unit is engineered for direct bolt-on installation between incompatible rotor bolt patterns. The black anodized aluminum construction provides corrosion resistance essential for long-term brake system reliability, particularly in off-road, marine, or high-moisture environments where standard finishes degrade quickly. The precision machining inherent to WILWOOD adapters ensures concentricity and eliminates runout that could compromise braking performance.

This adapter is intended for enthusiasts and technicians performing brake system retrofits where OEM rotor patterns must be modified to accommodate wide-5 hubs—common in hot rod builds, vintage vehicle restorations, and custom off-road applications. Vehicle platforms with 8 x 7 inch bolt pattern rotors requiring Wide 5 conversion now have a purpose-built mechanical solution that avoids the complexity and cost of complete brake system replacement while maintaining WILWOOD's reputation for precision brake components.
