Brake Rotor Adapter Open Wheel

The Brake Rotor Adapter Open Wheel from WILWOOD is a precision mechanical component designed for automotive enthusiasts and professional fabricators who require exact caliper-to-rotor alignment on custom and high-performance vehicle builds. This adapter is essential for bridging the gap between aftermarket brake systems and open-wheel or specialty wheel applications where factory mounting points may not exist or need modification.

Manufactured by WILWOOD, a leader in brake system innovation, this adapter features precision-cast or machined construction that meets strict tolerance specifications. This ensures zero runout and consistent brake response across repeated heat cycles. The open-wheel design prevents interference with wheel spokes, centerlock fasteners, or lug-nut patterns common in motorsports applications, while maintaining structural integrity under hard braking loads.

Weighing just 0.51 pounds, this adapter is compact enough to fit tight suspension geometries without adding unsprung mass that could compromise handling. It is ideal for fabricators working on vintage-to-modern restorations, drift platforms, and competition vehicles where OEM brake systems may not suffice.
