You gotta do it man, you'll have a great day man.
My insurance covers me for the track also, it's a little more expensive, but that's cool.
The only thing i do before i go on track day is tape up all the lights with strips of duct tape.
Stiffen the shocks up and go to the local fuel station that have 110% octain fuel.
Oil change so i have fresh oil.
Make sure my boost is at 1.2bar for the day depending on the the out side temp and make sure i have a full tank of water for the water injection!
Make sure your break pads are up to scratch man, you'll be coming in with red or even white hot disks....
