Product details
This left AERO6 uses a hard-anodized forged body and six 1.62/1.12/1.12-inch stainless pistons. Its radial mounting and type 6617 pad cavity suit assemblies designed around the caliper’s exact rotor and piston-volume specification. From its base in Camarillo, California, Wilwood Engineering designs and manufactures disc brake systems and components. Founded by Bill Wood in 1977, its range includes calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications.

Fitment & Compatibility
Check the left-side rotor direction and ensure an accessible upper bleed point. Rotor width is nominally 1.25 inches; compare the 1.10–1.28-inch clearance range and bracket position before installation.
With 20+ years of experience, PMB Performance can help compare the actual brake hardware. Supply the caliper number, rotor dimensions and mounting measurements when asking about compatibility.
