Chassis 2A003, the third Chaparral 2, had already met with great success (6 wins in 13 races) when it was rebuilt as the new "2/2C". This update included the aerodynamic "tricks" from the new Chaparral 2C. Most notable was the wild 'Flipper' wing!
 
The moveable rear 'Flipper' wing showed the way forward, the entire science of aerodynamics being in its infancy at the time. The driver operated a hydraulic actuator to adjust the angle of the rear spoiler during a race; it could be set to a very aggressive angle for maximum downforce in the corners, or to lie horizontally for minimum drag and maximum top speed! The competition really never had a chance.
 
Many teams would have been satisfied with such a massive advance; the 2/2C went on to win every race it entered, including its debut race at the L.A. Times Grand Prix. But for Chaparral, good was never good enough and even more daring developments were already in the works.
