1963 Italian Grand Prix
The 1963 Italian Grand Prix was a Formula One motor race held at Monza on September 8, 1963. It was the seventh of ten races in both the 1963 World Championship of Drivers and the 1963 International Cup for Formula One Manufacturers. At this race, Scottish driver Jim Clark clinched the World Championship crown with three races to go, the first time anyone had done so. The organisers had planned to run on the full 10 km circuit but the very bumpy (and in some places ruined) nature of the banked concrete curves provoked much criticism  and also caused accidents. Therefore, at the drivers' request, for the next day it was decided to revert to the 5.75 km road layout. This race was Scuderia Ferrari's 100th start in a World Championship event as a team. Jim Clark became the first driver to win the Drivers' World Championship with 3 races left to go. Lotus-Climax also won the Constructors' Championship.
