Product details
This red AERO6 is specified for the right side and uses six differential-bore stainless pistons. The 1.62/1.12/1.12-inch layout defines its hydraulic requirements, while the forged body is arranged for 7.09-inch radial mounting. Founded in 1977 by Bill Wood, Camarillo, California-based Wilwood Engineering designs and manufactures disc braking systems. Its motorsport, street-performance and specialized range covers calipers, brake rotors, master cylinders, valves, fittings and brake lines, selected as parts of a complete system.

Fitment & Compatibility
A matching rotor must fit the selected 1.25-inch nominal width version. Confirm the correct 6617 pad shape and caliper-to-wheel clearance after establishing rotor centering on the right-side bracket.
