The new ZO6 is a handfull if you don't have a lot of seat time. If you can run high 12's low 13's try out the next Z06 you come across. The ZO6 has run high 10's stock but a lot of guys are having trouble making mid 12's. It's all about the driver. An average (stock) ZO6 with a good driver is capable of mid 11's and low 11's with a top noch driver. With headers, DR's and tuning, most will run into the 10's. Awesome car with the right driver.:smile:
