Product details
With 6 pistons and 1.75/1.38/1.38-inch bore dimensions, the anodized Wilwood AV6R-ST left brake caliper must be matched to the brake system rather than selected by finish alone. Its 1.30-inch rotor-width specification is separate from rotor diameter. 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. AV6R is a forged six-piston radial caliper with a specific bracket offset. This exact unit must be selected by its piston material and bore combination as well as rotor width; the AV6R range contains configurations that are not interchangeable.

Fitment & Compatibility
Compare the caliper drawing with your radial bracket before ordering. The 7.09-inch mounting centers and 1.75/1.38/1.38-inch bores must suit the installed rotor offset and hydraulic system. Use the left-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.
