There are a lot of new developments happening with the 2023 25 Hours of Thunderhill, the longest closed-course endurance race in North America.
NASA announced last year that the event was moving to Nov. 10-12, 2023, which gets the event out of the middle of the holiday season and right at the end of the customary racing season, a move designed to boost appeal and attendance.
Since that time, NASA NorCal has made more changes and improvements to classing, tire rules registration processes and more. We have reported on those developments in Speed News previously, but we wanted to sit down with NASA NorCal Regional Director Jerry Kunzman and NorCal business manager Tasha Bigelow to get the “Federalist Papers,” if you will, the reasoning behind these changes. The comments below should provide more insight to changes made one of the world’s most challenging amateur motorsports events.
