To make a proper race car from a street car, you need aero changes to generate more downforce. To make an endurance racer from a street car, you need ample thermal management, i.e. cooling. From the few pictures available at the Ford Media Center, we can spot a number of the changes required to convert the Ford GT street car into a Le Mans winning race car.
One of the obvious aero changes is the elimination of the stock wing which is an active piece adjustable for height and pitch. Active aero is banned from nearly every form of motorsports, so a more proper fixed single element race wing was added. The wing is much wider than the stock rear wing along with being higher up in the air stream which should give it some cleaner air. Both of these changes should allow the race wing to generate significantly more downforce than the street car. On a side note, the Ford GT is drastically different than any other street car with its teardrop shape starting at the front of the car and terminating at the rear of the engine bay. The rear wheels are housed in pods that protrude from the bodywork much like an LMP car.
