The z06 was surprisingly one of the easiest cars to drive on the track from my experience. Your going to love it. And once you figure out the limits the semi vague steering is a non issue on track. There wasn't a soul that had a ride in my z06 that didn't walk away impressed or even flabbergasted.
My first track day in that car was my first time out at Laguna seca in a torrential down pour and I was still able to hit 2:01.
