Ha, was hoping nobody would see this circus but family...yes it's a stock c5 z06 with a Corsa Extreme. This was the fastest run of the day, beating 6-8 C7s, c6, and a c5. Also beat a lot of ice racers with super light cars, one tube frame car had a Maserati engine. I'm happy, only my 2nd season doing autocross. Wicked bumpy.
