Wilwood Black Right Dynapro 6A Brake Caliper, 0.38-Inch Rotor Width / 1.62/1.38/1.38-Inch Bores

The black right DP6A combines a narrow 0.38-inch nominal rotor-width cavity with six differential stainless pistons. Its 1.62/1.38/1.38-inch bores are carried in a forged aluminum body with reinforced bridge sections. 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.

Technical Details

Fitment & Compatibility

Check the rotor’s full thickness before ordering this narrow-body version. Verify the 5.25-inch lug spacing and 2.03-inch mount height, and ensure that the rotor’s usable radius suits the 6712 pads.

Ask PMB Performance to check the complete brake arrangement before ordering. Our team brings over 20 years of experience; photographs and measured bracket and rotor dimensions make that check more useful.
