My best lap time at Gingerman Raceway is a little over a second quicker in the Camaro than the Vette. The Vette feels.like a go kart in comparison, low and light. The Camaro benefits from 15 years of technology. I still consider the Vette a modern car, but it's very analog in comparison.
The brakes are a noticeable difference. The Z06 stops well for a few laps, then the brakes get hot and fade. The Brembos on the Camaro can go all day without giving up.
