Unfortunately I messed up my gopro videos, this means I only have this "off center" mobile phone to share. 
1st day (08/10) was plagued by red flags and I couldn't set into a rhythm, best lap was 1:58:xx which is the same I did 1 year ago despite this time I'm using Eagle F1 Supercar 3R tires (much more grip compared to the Continental sport contact 02 I used 1 year ago).
Second day I got to play with grip levels, gaining confidence with trailbraking and throttle steering. I got to a place where I could easily go below 1:54 every lap, towards end of day I consistently lapped in 1:53 and I got a best (while solo) of 1:52:xx. There's still A LOT to improve, the car has enormous potential, there are at least 5 easy seconds to be gained.

The Camaro Z/28 is an undervalued monster: yes it's heavy, but despite the weight it has insane grip/cornering speed, fantastic braking and enough torque to cover any gearing mistake. 

ACNW proves to be a fantastic group with excellent instructors, 10/10 recommended.
