if its like last time (99% will be) its self-scrutineering. by signing the application form, you agree that your car is roadworthy and isnt going to dump 5L of Motul on turn 1. usually 3 groups of 20 mins each, slow med fast, you sort yourself into your own groups.by about lunch time, people with issues or those coming off early creates more space in each group, so there will be plenty of sessions with little to f**k all cars on the track, so dont sweat it if your not in your preferred group in the morning.
just make sure you wear or take a long sleeve cotton shirt with you, you can grab one from cotton on for $20, long pants, and your helmet. Fire extinguishers not required.
