We will use MMSA rules for Stock 4

 

 The Monster Mini Stock Association (MMSA) strives for the best 4-cylinder competition around, hands down. The following rules and regulations set forth herein are designed to provide for the orderly conduct of racing events and to establish minimum acceptable requirements for such events. These rules shall govern the condition of all events sponsored and conducted by MMSA. These rules and regulations are subject to change/ or be adjusted from time to time by the series director/ his appointee, with the participants being given prior notice. By participating in these events, all participants are agreeing to comply with these rules and regulations. However certain rules and regulations are set forth by each track that will have to be adhered to. No expressed or implied warranty of safety shall result from publication of or compliance with these rules or regulations. They are intended as a guide for the conduct of the sport for each competitor and spectator. Membership is $75 per year. Entry fees for standard races are $100 for members $110 for non members We would like to give our best wishes to each of you for the upcoming season. RACE PROCEDURE: SIGN IN: Must have someone to pay the entry fee in person to be put on the list. RACE: On any start or restart, anyone jumping out of line or firing before the green is out will be warned ONE time. Do it a second time and you will be put back ONE ROW. Do it a third time and you will go to the TAIL OF THE FIELD. RESTARTS: We will go back to the true Double File restarts unless you are told differently at the driver’s meeting. In the event of a caution with 5 laps or less, we will go single file for the restart. We will attempt to finish each race under a green flag condition as permitted. Series Director/ Race Director will have final say. A lap is complete when the leader plus 4 crosses the line (Top 5). Any infraction of the rules that are not listed will be dealt with at the time of infraction and penalties imposed up to suspension from the series depending on the nature of the infraction. MMSA HAS THE FINAL SAY! All money won during the race event or a protest MUST be picked up that night at the end of the event unless special arrangements have been made, or it will be considered forfeited. DRIVER and CREW CONDUCT: There should be respect and compassion for every race team, track promoter, track official, and MMSA official. We must all professionally carry ourselves at every event. The MMSA wants everyone to experience a great time with HARD, CLEAN racing for these bigger purses. Keep in mind, if we go to these tracks and do not civilly conduct ourselves (arguing, fighting, etc) these tracks will not have us back. It is the goal of the MMSA for our competitors to put on a good show, take your cars home in one piece and be ready for our next event.Along with clean racing, we expect the crews to treat others with the same respect. DRIVERS are responsible for EVERY crew member on their team. If your team is aggressive or initiates a fight with another MMSA race team, track official, or MMSA official, the DRIVER of the aggressor’s team will be penalized. Punishable Offenses: • Hitting another car under caution or after the race has been completed • aggressively exiting your car and approaching a competitor (This includes the pit area). • Acrew member aggressively engaging another driver/crew. (This can also include texting, using social media, and other means). • Cursing track or MMSAofficials. • Failure to comply with these policies can include a fine, dismissal from the event, seasonal ban or could result in a lifetime ban. Any act that MMSAdeems as intentional could result in the following penalties. First Offense: Two-race suspension; points and monies forfeited for that night and possible fines before reinstatement. Second Offense: Banned for the remainder of the MMSAseason; monies for that night and points for the ENTIRE season forfeited and possible fines before reinstatement. Third Offense: LIFETIME ban from ALL MMSAevent’s. Pre-Race Inspection: All cars must go through pre-race inspection at the direction of series officials. At this point, an MMSA official has the right to check the following: carburetor, suspension, body, safety, and chassis. Driver/ Crew is responsible for informing MMSA/ Track Tech of any discrepancy at this time. All heat shields are to be removed at this time. If found not to meet MMSA rules you could be subject to change the part or add weight at this time. Pre-Race inspection ends when the drivers’ meeting starts, you must be in line.
