Also depends whether you're looking for the highest single payout or the highest fame per minute, which is more relevant for farming.

While EC and EK do pay more per event, they still pay less fame per minute than CFS 4-lapper. The best faming race IMO is in Campionato Scuderia Ferrari, 17.1 One lap Head to Head, which pays almost as much fame/min as MP4-X ES Endurance (3.1)
