No factory type seat belts may be used. Metal to metal buckles required on shoulder and seat belts. All belts must be dated no more than three (3) years old. If not dated, it is assumed the date has expired and they will not be allowed.
The ONLY recognized date will be the manufactured date as stamped on the seat belt manufacturers tag. No sales receipt will be recognized. Driver will be given one (1) warning to get belts replaced before the next race. The second warning, the belts MUST be replaced before the car will be allowed to participate in any further competition.
(E) Window nets are highly recommended. Roll cage padding is MANDATORY wherever drivers head or extremeties can contact roll bars.
ADDITIONAL INFORMATION
(A)The scales which are used at any event will be considered the events official scales. The reading of these scales will be used as the official weight of the car for the event. It is recommended that all participants check the weight of their car to assure that the car weighs 2400 pounds according to the scales being used.
Minimum weight of two thousand four hundred (2400) pounds must be maintained. Weight includes driver after the race.
Driver of car must be the person who weighs with the car. Official will verify drivers identity. Should driver who drove car in race not bring the car to the scales, then that car is disqualified from that race.
The top five finishing cars, minimum, in each and every race must be weighed after each race.
Cars MUST GO DIRECTLY TO SCALES AFTER RACE TO BE WEIGHED. Do not go to your pit or any other pit area, then return to scales.
Failure to immediately report to scales will result in automatic disqualification from previous event.
Track officials have the right to require that a car be cleaned before weighing, if in the officials opinion, that excessive weight has been gained from mud accumulated from the track.
Cars which are disqualified from heat races for weight violations of any kind will be put on the tail of a “C” or “B”-Main. If car count dictates that all cars are in the feature then disqualified cars will start on the tail.
Should a car not meet minimum weight:
Car will be disqualified from that race and all cars finishing behind that car will be moved up one position.
Cars which are disqualified from the feature for rules violations of any kind will forfeit their points for that race, and any prize money for that race.
No driver competing in another class may compete in the HotMod division during the same event.
(B) Use of any type of "traction control" is absolutely forbidden in any event. For purposes of clarity, "traction control" shall refer to any device, controlled by mechanical or electrical means, including driver controlled ignition timing or fuel delivery devices.
(C) Officials may inspect any car they suspect could be benefiting from the use of “illegal” performance enhancing parts or devices at any time. Driver/crew of car called to be inspected are expected to cooperate in a sportsman-like manner with inspector(s).
Failure to cooperate with inspector(s) will be considered an indictment of guilt on the competitors part, and competitor will be found in violation of this rule. NO EXCEPTIONS!
Any competitor (driver) whose car "illegal" part/s were found shall be found in violation of rules and will sacrifice any points accumulated to date that season and shall not be eligible for any point fund and/or contingency money/awards possibly due that season. In addition, the competitor (driver) shall not be eligible for competition in ‘HotMod’ division event for twelve (12) calendar months from date of the ruling.
(D) Rules may be altered as needed to maintain safety or economical integrity, improve competition, or for clarification purposes.
Track officials determination of legality will be final.
This class is intended as an economical option for competitors.
Do not assume if a particular question is not addressed in the above rules that it is automatically legal.
If you have questions about the legality of any proposed ideas for your race car, it is better to ask in advance, than be determined to be illegal later. Questions and their answers will be kept in confidence.
Do not purposely violate the intent of these rules.
