The rules in this book are intended to make racing less expensive and keep competition as equal as possible. While these rules offer a good outline, every item cannot be covered by a written rule. If you come up with something not covered in the rules, PLEASE ASK FIRST!

All rules in the NASCAR Rulebook will be enforced with the following changes and additions. These rules are for Stafford Motor Speedway only with no expressed or implied agreement with any other speedway as to the interpretation, implementation and method of inspection by the technical inspectors and officials.

No equipment will be considered as having been approved by reason of having previously passed through inspection unobserved. No car will be considered as having passed inspection for the event until the finish is made official.

NOTE: All engine models, equipment changes, or modifications not specifically addressed in these rule books by Stafford Motor Speedway must be submitted to the track for consideration of approval on or prior to September 2, 2011 unless otherwise authorized by Stafford Motor Speedway to be considered for competition for the 2012 season. All equipment is subject to the approval of the track officials. Track officials may assess penalties including but not limited to weight, fines, points, or handicapping for cars, car parts, components, and/or equipment deemed as not in compliance with these rules. Car parts, components, and/or equipment will not be considered as having been approved by reason of having passed through inspection at any time or any number of times unobserved or undetected. Any car, car part, component, and/or equipment which does not conform to specifications or tolerances contained in the 2011 rule books or is not otherwise approved by Stafford Motor Speedway may not be used in competition in 2011. Any new part or component to be considered for approval for competition must be submitted to Stafford Motor Speedway. The owner/driver must provide all information and/or parts or components to Stafford Motor Speedway and must provide any part or components to be used as comparison items for inspection purposes.

DEFINITION OF STOCK: In the following Rules you will see the term OEM Stock used. This means Original Equipment Manufacturer. The parts must come on a standard production car. Special "Off-Road" or racing parts will not be permitted unless pre-approved. No carbon fiber or titanium engine, chassis or body parts unless approved by track officials.

ILLEGAL ITEMS - Absolutely NO removal of, alteration of, or covering of casting numbers, part numbers, manufacturers name, logo, insignia, etc., from any item on the race car. To do so makes a part illegal and will be treated as such. If you come up with a rare part that we cannot find listed for passenger car use, the burden of proof is on you. At any time you may be asked to remove a head, manifold or possibly an entire engine for inspection. Failure to comply will result in the same penalty as if it were illegal.

INSPECTION - All model, engine or equipment changes or modifications not specifically addressed in this rulebook must be submitted to Stafford Speedway for consideration of approval. All equipment is subject to the approval of Track Officials. Equipment will not be considered as having been approved by reason of having passed through inspection unobserved. Any equipment that does not conform to specifications or tolerances contained in this rulebook or is not otherwise approved by Stafford Speedway may not be used in competition.

POST RACE INSPECTION - Once a car has been presented to Stafford Technical Inspectors for post race inspection the entire car and all its parts become subject to inspection. This includes but is not limited to items designated for inspection following a particular event.

SCALES - For purpose of post race inspection drivers must seated in their cars in a racing position with helmet either on or placed in their lap. No leaning or hanging on bars is permitted. The driver must remain in his/her car until it is removed from the scale area.

ABSOLUTLY NO SOMKING ALLOWED IN THE FENCED IN TECH AREA.

The rules in this book may be added to, deleted from or changed at any time with the only notice to be given at the event drivers meeting or via technical bulletin. All officials’ decisions are final, non-appealable and non-litigable. Technical bulletins will be issued as needed.

UPDATES - All changes and updates made during the course of the season for the current rulebook will be posted to the Stafford Motor Speedway website. This will serve as the only form of official notification until the printing of next Stafford Motor Speedway rulebook.

SECTION 1-4

All NASCAR Rules will be enforced with the exception of the following STAFFORD SPEEDWAY TRACK RULES. These rules supersede any similar NASCAR Rules and are in effect for all auto racing events unless otherwise posted and/or announced prior to the event.

NOTE: Some Track Rules may not apply to touring divisions.

SECTION 6 SAFETY

Stock car racing is an inherently dangerous sport. Each Competitor assumes that risk when he or she participates in an Event. The risk of serious injury or death cannot be eliminated and in fact will always be present at a high level. Members are required to advise their spouses and next of kin, if any, of this fact. Although safety is generally everyone’s concern, Stafford Motor Speedway cannot be, and is not responsible for all or even most aspects of the safety effort. That responsibility instead rests with the various participants in the Event(s) as follows.

All competitors are obligated to inspect the racing facilities, safety personnel and equipment, and conditions at the track on a continuing basis, before, during and after the event. Competitors must report to Stafford Motor Speedway management promptly any inadequacy in the facilities, personnel, equipment or conditions at the track.

PASSENGERS are not permitted in or on a racecar at any time. No one shall ride with any part of his or her body outside the racecar. No riding on trailers or car haulers or pit carts anywhere on the speedway property. NEITHER STAFFORD MOTOR SPEEDWAY NOR TRACK OFFICIALS CAN OR WILL BE RESPONSIBLE FOR THE ADEQUACY OF A COMPETITOR’S RACECAR, RACING EQUIPMENT OR RACING ACTIVITY TO ACCOMPLISH THIS PURPOSE.

SECTION 9 RACE PROCEDURE

1. All cars must go into the infield before turning into the off-track paddock gate except at the conclusion of the feature event. No right turn from the track to the paddock. All cars must go through the infield road after each warm-up session and qualifying event. After feature events cars may go directly into the paddock area without going through the infield. The first three (3) cars in the feature finish must report to victory lane. DO NOT DO BURNOUTS OR DONUTS ANYWHERE ON THE RACE TRACK OR INFIELD AFTER THE FEATURE EVENT OR AT ANY OTHER TIME.

SECTION 9.5 HANDICAPPING Note: Some rules do not apply to DARE STOCK Division.

All drivers must complete a Number Application form before signing in.

For all events your car must be signed in 45 MINUTES before the first heat race is scheduled. Once the line-ups are posted no additional cars may be added. If your car is signed in but does not arrive you may be credited with two wins for handicap purposes.

When you sign in your car state your division, assigned car number and the driver’s name. If you bring two cars, one as a BACK-UP CAR you must decide and indicate which car will be your primary car when you sign in. Drivers will be handicapped on a 3-week money won system. For handicapping purposes regular feature event purses will be used. Any driver that misses an event will be credited with a regular feature win in money plus 1/2 feature win in money for handicapping purposes. Any driver disqualified from a feature event will be credited with a regular feature win plus 1/2-feature win in money for handicapping purposes. The top 18 drivers in points will be handicapped ahead of drivers not in the top 18 for the main feature only.

No current season feature-winning driver may be posted to start higher than fifth position in a feature event.

Note: For some events the top ten cars in points may be considered as pre-qualified. The car must still be signed in 45 minutes before racing starts to take advantage of being pre-qualified.

All alternate feature cars will be taken from the consolation event. If a car is disqualified from a heat additional cars will not be taken from heats but from the consolation or ‘B’ feature.

If in the opinion of the Racing Director a car is not competitive on a given night, he has the authority to deny that driver a front starting position.

For additional handicapping information please ask handicapper for clarification.
