I've been rocking the work trousers all week so far tbh, shirt tomorrow as well, that'll be on just for the grid walk and then it'll be back into polo shirts, as soon as the checkered flag drops we'll be starting packup, getting to the track just before 5am tomorrow and then probably won't get out until 7/8pm, Sunday we'll pack whatever late stuff turns up and then back to the hotel, flight out is 5am Monday morning..
As for the actual race itself, its warm and humid which will effect battery and tyres, track was just over 10oC hotter than the air temp today, tomorrow when the cars are running it'll be a bit more, major factor will be the weather, we've been having storm warnings all week and had nothing until yesterday when it really opened up..
