Corvette Racing have reasserted their commitment to the American Le Mans Series and say they believe the level of competition in the GT1 class will improve in the future.
The yellow cars had very little opposition in the series in 2007 following Aston Martin's decision not to compete, but Corvette will remain in the series next year.
GM Racing's road racing manager Steve Wesoloski said: "Experience teaches us that motorsport is cyclical, and the GT1 category is currently in transition.
"Would we like to see more competition in GT1 in the ALMS? Absolutely. But in the absence of season-long competition, we are absolutely committed to controlling our own destiny."
