Wilwood Competition Blue DPHA Front Caliper, Honda/Acura 262mm Brake System

The Competition Blue Wilwood DPHA is a four-piston front caliper for Honda and Acura brake assemblies originally equipped with 262 mm rotors. Its forged aluminum body carries equal 1.62-inch stainless pistons and bolts to the original spindle mounts for that brake configuration. Wilwood Engineering, founded by Bill Wood in 1977, is based in Camarillo, California. The company makes and designs disc brake components and systems for motorsport, street-performance and specialized applications, including calipers, brake rotors, master cylinders, valves, fittings and brake lines.

Fitment & Compatibility
