SDR ENDURANCE TOUR SEASON 7
THE ULTIMATE STRATEGY & SPEED SHOWDOWN
PLEASE JOIN iRACING LEAGUE – 11908
Get ready for another season of high-intensity, strategy-driven multiclass endurance racing as we launch Season 7 of the IMSA Endurance Tour! This season’s championship will feature a 6-race calendar taking inspiration from the official iRacing IMSA schedule. Powered by an open setup philosophy and restricted fuel capacities, success requires far more than one-lap pace—tire life, traffic navigation, and pit execution will determine who takes the crown.
Every round features live stewarding and full live broadcast commentary on the official SDR YouTube Channel.
