Depends how wet it was, but you can lose an astronomical amount of time with the wrong tires in wet conditions.I think they pitted because of the rain. I was on stock tires. Every other car always seems to have racing tires yet a lower PI. 1 lap to go and 7 cars in front of me pit to change to wets (I'm assuming) this is in the builders cup btw.
I just thought that was hilarious.
