This ^^^^^ is absolutely crucial with a first time car. Take your time and just get the feel of things.
There's so much to get the hang of at first, it would almost be impossible to tell you everything in one post. Make some safe passes, log some data about, leave rpm, shift points, tire pressure, etc. Main thing the first time out, take it slow and get the feel of things. Use your senses and you butt to tell you how far to take it for now. Once you get used to it, experiment, experiment, experiment, with different adjustments. Could take you all summer to get it totally right. Importantly, stay safe and have fun.
Just curious, i assume it's the first time out for the car, but will this be your first time on the track?
