the red CSX4000 series car driven by A.C. D'Augustine wrecked on the final race on Sunday. He was battling a Porsche all weekend long and they tangled and he ended up in the wall by turn five. The majority of the opinions that I heard were that the Porsche was in the wrong and was the cause of the crash. I did not see the crash myself.
A.C. was not hurt but the car suffered some significant front end damage.
