Sebring 12 Hour race won by Phil Hill and Olivier Gendebien in a works Ferrari.
Phil Hill and Olivier Gendebien won the Sebring 12 Hour World Sports Car Championship race in a works Ferrari. Masten Gregory led early in a rear-engined Camoradi Maserati before Pedro & Ricardo Rodriguez took over in a Ferrari. Stops put the Ferrari Dino of Wolfgang von Trips out front, but his steering broke to move the Rodriguez' brothers back into the lead. Defective rear lights cost the Rodriguez's badly after dark, giving the lead to Hill and Gendebien.
