To receive an invitation to the Nitto Triple Crown, drivers must either finish KOH 2018 in the 4400 class or have finished top 20 in the 2017 ULTRA4 Nitto National Championship Series. All drivers invited to race at the Mint as part of the series will have a chance to race the Friday night Ultracross feature race in Crandon, but only the top 30 drivers from Friday night’s race will make it into the main event — the Crandon World Cup on Labor Day Sunday to be crowned a Crandon World Champion and the winner of the Nitto Triple Crown. All Drivers must commit to an ULTRA4 Regional Series to participate in The Triple Crown. These are additional races and cannot be raced in lieu of regional races.
