In 1962 the FIA, addressing concerns to reduce the speeds attained in sports car racing following the disastrous accident at Le Mans in 1955, shifted focus from Appendix C Sports Cars to production based GT cars of Appendix J. The previous World Sportscar Championship title was discontinued, being replaced by the International Championship for GT Manufacturers, won by the Ferrari 250 GTO in 1962, 1963 and 1964.
