Driver Jeff Stammer kept his cool and his race alive when he averted tragedy when a car re-entered the track over the blind crest after Turn 1 at last year’s 25 Hours of Thunderhill presented by Hawk Performance. Team Stammer Inc./Bavarian Performance went on to finish fourth in ES class, which had the most entrants at last year’s event. Fifteen ES cars took the green flag to start the race.
