--------------------------------------------------------------------------------------------------------------------------------
Children Racers
Children, under the age of 16, but at least 10, who
are directly related to an ISF member (i.e. son, daughter, nephew, etc.) may
race in the GTP, F1, GT & LMP categories if they can meet the following
criteria:
1
-- their best qualifying lap is within 120% of the polesitter's time
for
example, if pole speed is 6.545 seconds, a time within 120%
must
be under 7.854 seconds
2
-- they had no more than two offs during their qualifying run
3 – they
can run at least two minutes at speed with three offs or less
These rules have been set to be sure that young racers
can show two things: good car control and good pace
The ISF founders felt that 120% would be a
reasonable mark for pace, and more than two offs in 12 laps would be a bit too
much
Rules apply to children racers until they prove that
they can meet these criteria on a consistent basis
--------------------------------------------------------------------------------------------------------------------------------
Tracks
- All
tracks have to be inspected and approved by ISF technical committee
- Plastic
guard rails attached to the track are not acceptable for new tracks

F1 Teams Special Rule
- Drivers can choose any manufactured car/sponsor
to race. F1 must represent a real F1 team from 1951 onward
- Drivers can create their own F1 team with
approval of ISF board, must be F1 related (i.e. Super Aguri = Super

a new driver, who shows up or is given, a temporary car to race)
- Drivers can race cars from the same team provided

colors)
