In 1966, Don Yenko was impressed enough with the late model Chevrolet Corvair’s handling, and decided to apply for SCCA approval of the Corsa model for racing. The sanctioning body approved the cars with back seat removed and upgrades to the Corsa engine increasing horsepower and torque. The 100 1966 Corsas that received certification were all painted white with blue striping, and were named “Yenko Stinger”.
