I decided to further fact-check your numbers, because well, you know.
In 2016 alone, 40,689 Corvettes were built. Of those, 14,275 were Z06 coupes and convertibles.
Of those 14,275 Z06s made in 2016, a whopping 4,955 were ordered with the optional Z07 package (today's equivalent of the Carbon Fiber wheel option). That's just short of 20,000 wheels in that year alone, Neil.
