Thats the main thing I was laughing at, 20 minutes per hour with a bunch of cars which haven't ever been on a track before... They'll be driving hard and max out temps after 2 hotlaps.
HIGH possibility that they'll identify weaknesses in the car (as everyone does on the first 3-4 track days) or break something or even minor stuff like popping off cooler pipes due to sustained boost and heat. Std brakes/pads/oil cooler/ps boiling/tyres running out
Nek minit they've missed 3 sessions trying to repair a car in the pits and it's cost them $100 worth of the day.
Tell you what though, with the number of GTR's that are down there... Racepace should be there offering advice and guidance to them... So many potential new customers who are getting a taste of the track bug
