Product details
The 7.09-inch radial attachment distinguishes this left Wilwood Aero6 brake caliper. This individual anodized unit is built for the 0.81-inch-wide rotor configuration and requires accurate alignment with the mating rotor and bracket. Founded by Bill Wood in 1977, Wilwood Engineering is based in Camarillo, California. It designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings and brake lines, for motorsport, street-performance and specialized applications. Components must be selected to suit the complete brake 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.

Fitment & Compatibility
Check bracket location and rotor sweep using the installation drawing; 7.09-inch radial mounting alone does not establish a vehicle fit. Use the left-hand caliper and keep the bleed arrangement in the specified orientation. Use the 1.75/1.38/1.38-inch piston-bore specification when reviewing hydraulic balance, and verify hose routing and wheel clearance.
