It's no secret that the C5/6R has been wildly sucessful. They have absolutely dominated their class for years. It seems now that the competition simply doesn't want to try.
GM's 2 car team finished first and second in class for the first two races of the season. Their only in class competitor has been the Aston Martin DB9 out of Bell Motorsports. After withdrawing from the third race, the C6R's were left to battle it out amongst themselves.
I found this link at
SpeedTV, discussing why Bell Motorsports didn't show?
Did they run out of money fix the car after a race 2 crash?
Did they simply not have enough time to fix the car.
or
are they simply tired of being beaten up by the Vette's?
