per event

  • Total number of competitors = total points for the final winner. (15 racers means 1st place gets 15 points)
  • 1 points less for each following place. (Same example, 2nd place gets 14 points, 3rd 13, etc.)
  • 1 bonus points awarded for having the fastest qualifying time.
  • Finishing results are final on day of G.P. and will not be changed.
  • In case of an incident during a position race, it will be the manager on duty decision to change positions accordingly after speaking to drivers involved.
  • If a driver initiates a retaliation of a race incident during or after a final position race, that driver will be dropped automatically to the final position spot in his group and loss of points.
  • If at the end of the season, there is a points tie, the driver with the best podium record will win.
Racing Format
  • There will be two qualifying rounds consisting of 14 laps each. Your single fastest lap time from both qualifiers will be used to determine your position at the start of the final race.
  • The final race will consist of a 16-lap race for position (14 laps in Carlsbad) and will begin as a grid standing start. 
  • There will only be ONE grid standing start! No restarts are allowed.
  • If a racer causes an intentional or avoidable incident (crash, spin-out, etc.) that results in loss-of-position for the other driver, then the racer-at-fault is sent to the back of the grid. The innocent driver will resume the race from wherever they rejoined the field. (e.g.: if they were second and drop back to fifth as a result of the incident, they’ll continue in fifth position, not second).
  • New drivers will be evenly distributed within qualifying groups.
Mechanical Issues
  • There will be no switching of karts at anytime during both qualifying sessions unless there is a mechanical failure or accident, which caused damage to a kart.
  • You will be able to remove a kart after the first round of qualifying.
  • You will be able to remove a kart after the second round of qualifying.
  • There will be no switching of karts during a final race unless there is a severe mechanical failure.
