These costs are based on 'A' team racings race.                
This novice team with four drivers, three of who were having their first race. The team was running 11th with 50 minutes to go, until the engine was over revved on a missed gear change.                
The team had one spare engine and gearbox, but had to borrow a front suspension arm after a testing crash on the Friday.                
The two front tryes were changed in the middle of the race. Six were used in total all weekend.                
Race refueling is by circuit supplied jerry can and nozzle. A couple more Jerry cans are useful. Fuel is supplied at the track throughout the race.
