Detailed parameters
Fuel is inevitable, it's consumption directly translates to track day price. Enter details.
| Fuel price | €/ltr. | |
|---|---|---|
| Fuel consumption in highway, ltr./km | ltr/100km. | |
| Fuel consumption in track, ltr./km | ltr/100km. |
Unless it's a Honda, your car runs on petrol or diesel. If it is a Honda, it runs on mixture of fuel and engine oil. Jokes aside, all engines consume or at least leak some oil, so that also translates to some expenses of having to top your sump.
| Oil price | €/ltr. | |
|---|---|---|
| Oil consumption in track, ltr./100km | ltr/100km. |
Have you got a parachute? Nope? Sad news. Your brake pads will wear rapidly on track. There will be heat, red hot metal and brake pads are known to go missing somewhere in 15 lap session inferno.
| Set of front pads, price | € | |

| Set of rear pads, price | € | |
| Front brake pad wear in percent per 100 km on track | %/100km | |
| Rear brake pad wear in percent per 100 km on track | %/100km |
You've most certainly got some components that will exhibit wear over time. It might not be very obvious at first, but most engines do have a limit of track hours they can live through. The same more or less applies to all other components, be it natural engine block wear or suspension damage due to driving mistakes that happen every now or then.
