On lap 27, the #12 Z was the first in the GT500 class to pit in, while the #3 Z and #24 Z made their first pit stops on lap 35, and the #23 Z on lap 36. On lap 43, just as all GT500 class cars were completing their first pit stop, a GT300 class car crashed, bringing out a full course yellow (FCY), followed by the safety car (SC). Then, after 6 laps behind the SC, the race was red-flagged at the end of lap 49 to repair the damaged barriers. At this point the #3 Z was 4th, the #23 Z 8th, the #12 Z 9th, and #24 Z 12th.
