INTERPRETATION OF THE RULES

Barona Speedway has encouraged the drivers in the Street Stock division to have a say in these rules. These rules are a result of meeting with current drivers in this division, and voting on key issues throughout these rules.
Though we have made every effort to provide rules that will be clear and precise, should there be any confusion in your interpretation, ASK!! IGNORANCE IS NOT AN EXCUSE! If a specific issue is not addressed in these rules, the official's decision is final. Any modifications not addressed in these rules will not be allowed unless approved by the Tech.
We want all cars to be competitive with each other in their division. If you do something with your car that has been overlooked in these rules that we feel gives you an unfair advantage over your competitors, YOU will be required to change YOUR car. These rules are provided to maintain orderly conduct of racing events and to establish requirements. By participating in Street Stock events at Barona Speedway, each driver agrees to comply with these rules and all general rules of the Speedway. Should your car be found in violation of these rules it will be the Tech's discretion as to what action will be taken. A minor 1st time infraction may allow you to race that night, but require you to make necessary changes prior to the next race. Any rule infraction will be given to you in writing. Should a racing advantage rule infraction be found, you may be asked to start in the back, or may not be scored or allowed to place in that event. You also may have to add weight to your car to compensate for the infraction. The amount of weight to be added will vary depending on the infraction, and will be determined by the Tech. You will need to find the weight required yourself, it will not be provided. Changes will need to be made to your car to comply with the rules prior to the next race night.
These rules will be in effect throughout the 2006 racing season.
These rules are in no way meant to imply any guarantee of safety. There is no guarantee against injury or death to participants, spectators or others.
These rules may be amended at any time by the Official. Changes may be made for safety, or to keep the competition close. The Barona Speedway management appreciates your cooperation in complying with these rules. We wish you all a safe and successful 2006 racing season.
