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

DS-1728 specifies C7 Corvette upright/hub applications. Read every trim and year in the table below: Stingray 2014–2019, Z51 2014–2016, Z06 2015–2019, Grand Sport 2017–2019 and ZR1 2019. Confirm the actual upright, hub and existing brake equipment before ordering; this conversion is not an assertion that those original brake packages are interchangeable. Flexlines are separate and wheel clearance must be checked against the kit drawing.
