Memorandum, "The Aerodynamics of the Ford GT40 Nose," May 18, 1965

In the mid-1960s, Ford Motor Company competed in endurance races with its all-new GT40 car. Daily racing efforts were managed by the Shelby American team. This memo, written by Shelby engineer and driver Ken Miles, described instability in the GT40's handling due to the shape of the car's nose. Miles had tested the car himself at Ford's Romeo, Michigan, proving ground.
