Competition rules:
It is the intention of the organisers to have dedicated races for this class of car. Each meeting will have
a minimum of 2 races. The first will be a scratch race and grid positions will be assigned according to each
drivers fastest lap times during the mandatory practise session. The second will be a handicap race based on
the fastest lap times achieved during the first race. The handicap positions will be calculated and assigned
by the chief organisers. If necessary the chief organisers, at the request of the competing registered drivers,
may grid the first race in two groups . The first group will be modified cars and the second group will be
unmodified cars. At the start of the scratch race the first flag fall will be for modified cars and 2 seconds
later a second flag fall will start the un-modified group who throughout the first 2 seconds will have remained
stationary at the rear of the grid. Unmodified cars that register a faster lap time than modified cars will
still start at the front of the second group.
Points will be awarded for the following placings:
First 10, Second 9, Third 8 etc
In addition points will be awarded for the following:
| Driving the car from home to the circuit: |
1 point. |
| Entering a race meeting: |
1 point. |
At the end of the season points will be tallied for each competitor.
The only points counted will be the highest each person registers at the number of meetings calculated
as one less than the total number of race meetings for the season.
