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.
