The 20-lap Richmond race in NASCAR All-Star Series awards more fame per race. Racing there would be roughly equal to the 10 laps Le Mans races, although you would have to worry about repair times.

Another option if you have a fully upgraded McLaren P1 GTR is the endurace race at Indianpolis Speedway. That race may be slightly better than Le Mans, although it would take around 5 hours of racing.
