Product details
Wilwood supplies this right Aero6 brake caliper with a red finish. Its 7.09-inch mounting span and 0.81-inch-wide rotor configuration are key checks when selecting a single caliper for an existing system. Aero6 is a forged six-piston hydraulic caliper with internal fluid passages. Differential piston bores, radial bracket spacing and rotor dimensions determine the assembly. Select the pad compound separately for the operating temperature and use of the complete brake system. The Wilwood disc brake range is designed and manufactured for motorsport, street-performance and specialized applications. It includes brake lines, fittings, valves and master cylinders together with calipers and brake rotors. Wilwood Engineering was founded in 1977 by Bill Wood and is based in Camarillo, California; its components must be matched to the complete braking system.

Fitment & Compatibility
Compare the caliper drawing with your radial bracket before ordering. The 7.09-inch mounting centers and 1.75/1.62/1.62-inch bores must suit the installed rotor offset and hydraulic system. Use the right-hand caliper and keep the bleed arrangement in the specified orientation. A suitable pad sweep and clearance inside the wheel must be verified independently of rotor width.
