HIGH POINTS- contingency money at the end of the year for high points. There are 33 classes that will be run at each location that fall under these rules. Money will be awarded for 1st, 2nd and 3rd place winners of each class at each race. Driver Numbers – are on a first come, first serve basis. Numbers will be issued at first race and that driver retains that number through the entire circuit. (Different driver needs to get new number) There will be no duplication of numbers. (Example-21x is not allowed) This reduces the chance of error in number keeping. Registered Driver must race; NO Driver Substitution or you will be DQ. Tech – If Racer wants another sled checked for possible alterations, he or she must specify the area this is questioned and deposit $100. If the Sled questioned is not stock, the Racer doing the questioning will receive his $100 back; if the sled was legal, the racer whose sled was checked keeps the $100. If your sled is checked and does not meet the rules for that class that it was entered, ALL points accumulated with that sled and driver for that day and prior events will be forfeited. Tethers must be worn at ALL TIMES while sled is running 100% PAYBACK Pay back 3 places $200 High Point per Day $25 Stock $75 Improved Stock $100 Mod Series Rules-You can race at any race, one or two local races, but to be in the series points you have to run 5 out of 6 events.
