The Cobra, perfected
Philosophy
Backdraft Racing's founding question was: what would Carroll Shelby have built if he had modern materials, a modern engine, and no regulatory constraints? The answer is not a perfect museum piece — it is a car that drives harder, is more reliable, and is more honest in its purpose than the original. The RT4 chassis is stiffer than a 427 SC. The LS engine lasts longer and makes more power. The carbon bodywork weighs less. Backdraft builds the Cobra as it should have been.
The Concord shop is a working production facility, not an assembly line. Each car is hand-welded, hand-laid, and hand-fitted by technicians who have built hundreds of these machines. The result is a level of panel consistency and structural integrity that replaces the beautiful imprecision of the 1960s originals with something genuinely better — while preserving everything that made the Cobra the defining American roadster.
