 (Clarifications in red)

            The rules set forth herein are designed to provide fair parameters for competition and a high level of safety. NO expressed or implied warranty of safety shall result from publications of or compliance with these rules and regulations, they are intended as a guide for the conduct of sport and are no way a guarantee against injury or death to a participant, spectator or official. Driver/ Car owner is legally responsible for all crew signed in under car.

It is the Driver/ Car owners' responsibility to ensure his or her car is legal, if there is a question about the rules, email or phone tech committee before you show up, non conforming cars will not be allowed to run except for minor variations. Tires and Safety rules are only subjected to review by Tech only.


Refer to the safety rules for the basic building rules (Roll cage, Bumpers, Fuel cell, Approved clothing, etc.)

2014 Safety Rule Change***Bone Stock Mini’s will have a minimum Safety requirement and a Maximum Safety Requirement in regards to their Roll Cages.  Cage Diagrams (on Page 37 in the Street Stock Rule area) are the minimum Requirement; with the addition of a Petty Bar; a bar that runs diagonally from the center bar down to the Right Front of the existing roll cage.  A maximum and suggested cage design will allow drivers to run bars out the firewalls of their cars and tie their strut or shock towers together.  Rear Wedge bars are also a minimum Safety Requirement for the 2014 season as well. If the Fuel Cell is mounted on the rear differential hump then the bars only need to run to the rear shock towers.  If the fuel cell is mounted where the spare tire would have been located then bars must be ran to the furthest most point of the trunk to safely protect the fuel cell in case of a collision from the rear.
