2013 Super Stock Rules (formerly Hobby Stock)
We mean what we say and know what we mean, so if you don't understand something, please ask us
The following specifications have been prepared by Path Valley Speedway as guidelines for the construction of a purely Super Stock low-cost V-8 racecar. No warranty of safety is expressed or implied as a result of this publication of rules. These are intended as a guide and are in no way a guarantee against injury or death to participants, spectators, or officials. Anything not covered by these specifications should be approved by the track officials and placed in writing. Continuous developments in auto racing and technology may mandate changes in these rules. However, it is our intent to enforce and police these rules throughout the season. If a change is necessary, technical bulletins will be prepared and distributed in advance. We strive to keep the competition equal and fair for all competitors. To accomplish this, if it doesn't say you can - DON'T! Try to live within the spirit of the rules.
If you have any questions, please contact track officials before you are found illegal for competition.
Ignorance of these rules is not an excuse for violations. If a car is found illegal, both the car and the driver will be disqualified for the night and no points, money or trophy will be awarded. Any car not willing to tear down will be considered in violation of the rules. Path Valley General Rules for all classes apply. Please read them and follow them.
