Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company 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.

Fitment & Compatibility
Check the exact model/year and spindle conditions in the table, then follow DS610 for the required spindle work. Inspect the bearings and wheel register before assembling the hats and friction rings. Hydraulic lines must be selected separately for the chassis. Use the clearance template to verify space behind the wheel spokes as well as around the rim barrel.
