In 1963, sports car racing in the United States was not ready for the impact that Carroll Shelby’s Cobra was about to bring to the party. Introduced in 1962, the Cobra, with its lightweight English chassis and American V8 power, was already a legend in the making on the street, but this chassis and two others were prepared as factory competition cars from the start. Specifications for CSX 2129 included newly adopted rack-and-pinion steering, a Ford 289 cubic-inch V8 with Weber carburetors, competition brakes and suspension components, quick-jack pads, Halibrand magnesium wheels, side-exit exhaust and auxiliary oil coolers. Driven primarily by Ken Miles through the 1963 racing season, CSX 2129 earned numerous class victories and pole positions, with nine podium finishes in 15 races. This record played a major role in Shelby-American’s win of the USRRC Manufacturer’s Championship, USRRC Driver’s Championship and an SCCA Championship that year. The car has been restored to its 1963 configuration and specification.
