This event is the Friday before NASA at Thunderhill Raceway and includes HPDE track activity as well as Race Testing for those of you planning to race with NASA over the weekend. This is TMR's and NASA's first event at Thunderhill for the 2023 season and it should be perfect weather conditions! This is also our 28th year of hosting events at Thunderhill!
