Kiwi Dominic Storey and Australian Peter Hackett drove away from the field to win the Laser Plumbing & Electrical Hampton Downs 500 in their Mercedes on Sunday.
Championship leaders Jaxon Evans and Tim Miles finished second to take a big step towards overall glory in their Audi R8 LMS. They made a great recovery after crashing in treacherous qualifying conditions and were forced to start 10th after missing the shootout.
Another Mercedes of Tony D'Alberto and Max Twigg was third.
Popular former NZ SuperTourers driver Storey qualified third fastest in the top 10 shootout on Saturday but was later handed a penalty that dropped them to ninth after he was judged to have gone out late on his shootout lap. The team was not happy with the call, claiming the race director called every other car when they were required, but took their penalty on Sunday.
Hackett made a superb start to Sunday's race however and got to third before he took an early pit stop. They jumped to the front after the first safety car intervention and held the spot through the remainder of the race.
