Corvette Racing faces one of its biggest challenges yet with their new ZR1-based GT2 Corvette C6.Rs at Road Atlanta this weekend. Round 7 of the American Le Mans Series is Petit Le Mans, the 10-hour/1,000 mile race in the rolling hills of Northest Georgia. Reliabilty was one of the hallmarks of the GT1 Corvette C6.Rs and now the GT2 cars will have their chance to prove they can go the distance as well.
