I was lucky enough to codrive a 2023 C8 Z06 at the APEX event Jan18, and I really enjoyed it! The car is POWERFUL and requires extreme throttle management on corner exit, but it rivals the Porsche GT3 in every way.
My best time in 3 sessions on this very cold day was 2.14.71 so there's a lot more out there. Hope I get the chance again sometime. Thank you Mike B. for sharing your awesome car!
