Founded in 1977 under Bill Wood, Wilwood Engineering operates from Camarillo, California. The company designs and manufactures disc brake systems and the calipers, rotors, master cylinders, valves, fittings and lines used within them. Its motorsport, street-performance and specialized applications depend on compatible brake components.

Fitment & Compatibility

Compare the 14.00-inch assembly in DS-1729 with the car and the table below. Stingray, Z51, Z06, Grand Sport and ZR1 have individual supported year ranges within 2014–2019; identify the actual upright, hub and brake package. This kit excludes flexlines. An 18-inch wheel is only a starting point: the spoke and barrel must clear the drawing.
