man 2hr stints would be amazing. 30 mins on a road course goes by so fast. so being able to be in the seat that is amazing. how about the tires, do you need to change them and what R compound?In the Champcar series we are limited to 18.1 gallons of fuel (2 gallons more than the OE tank), and we should be able to get 2-hour stints with that at most tracks. There are currently displacement blocks in the cell so it can't take more than 18 gallons. I can remove them for other series to get the full 22 gallons.
