I went to Moroso to get some practice

Didn't do too hot but, oh well
After a few runs, I decided to go and watch for a bit and I saw a gorgeous new blue Z06 waiting to run(some car broke a few cars before him). Finally, they clean it up and ready to go. The guy had a swarm of people stalking the car as he inched up. The car looked and sounded stock to me, simply beautiful. I finally get to see a new Z run.
The light turns green "pop" car shuts off

It didn't even look like he even moved an inch. I was only about 15 ft away when it happened. I felt absoluetly terrible for the guy. There were a bunch of morons laughing in the stands and such like morons do.
They push the car back into a spot and the crowd once again swarmed. I walked over and just tried to listen in the distance but, couldn't make out what had happened. About an hour or so later, I saw it being towed away by a flatbed.
A guy I met who says he checks this site out and the other vette site out said he had found out it was the rear. Wierd thing is I swear I didn't even see the tire move one inch. He didn't seem to rev it high or anything. I dunno if he is a member here but, if he is, sorry about what happened and I hope they take care of it for you. I'm sure they will.
I'd just love to know what it really was and why it happened
Any of you guys hear of anything like this?
