Also added this year – Dakota Connection Speedway in Sisseton, SD!

It is YOUR responsibility to read, understand, and adhere to all these rules!

AGAIN IN 2016 – We will be running an accumulative points system with the participating tracks for the full size cars.  These points will lead to an Enduro Car Racing Points Champion at the end of the racing season. It is also at each track’s discretion to have a Track Champion. Points will be awarded in 3 areas; participation (show up & pay entry = 30 pts), laps completed (1 lap = 1 pt.), AND race position (finish 1st = 20pts., 2nd = 18pts., 3rd = 16pts., etc.).  There will be a monetary award and likely other prizes for top ranking points finishers at the end of the season.  These points will be awarded to the car/team & are accumulated in that way only. Drivers will be limited to 2 per car & must be declared at first event participated in (no later substitutions).

EXAMPLES:   If you finish 3rd with 133 laps and pass inspection you would receive 30+133+16=179 points

                   If you finish 6th with 117 laps and pass inspection you would receive 30+117+10=157 points

                   If you finish 11th with 92 laps and pass inspection you would receive 30+92=122 points
