Product details
For a nominal 0.81-inch rotor width, this anodized Narrow Dynalite provides four equal 1.75-inch stainless pistons. The forged body uses internal crossovers and the 7816 or 7216 pad arrangement. With a range spanning calipers, brake rotors, master cylinders, valves, fittings and brake lines, Wilwood Engineering designs and manufactures complete disc braking systems and their components. Bill Wood founded the Camarillo, California-based company in 1977 for a market now covering motorsport, street-performance and specialized applications.

Fitment & Compatibility
Compare the 4.80-square-inch effective area with the brake circuit. The 3.50-inch lug pattern must be paired with the right rotor offset and pad sweep, not merely a similar-looking bracket.
