2010 SANDUSKY SPEEDWAY BUCKEYE SUPER SPRINT RULES

Printable Version

IMPORTANT: The following specifications have been prepared by Sandusky Speedway as guidelines for the construction of a 305 Sprint. No warranty of safety is expressed or implied as a result of this publication of rules. These rules are intended as a guide and are in no way a guarantee against injury or death to participants, spectators, or others. Anything not covered by these specifications should be approved by the track officials and placed in writing. Common developments in auto racing and technology may mandate changes in these specifications. 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.

NOTICE: This division is being developed for the fun of racing in a low cost fashion. This requires limits in various areas to keep competition equal and fair for all participants. In order to accomplish this, if it doesn’t say you CAN, DON’T. With the help and consideration of the participants this can be accomplished. Try to live within the spirit of the rules. If you have questions, please contact track officials before you are found illegal for competition.
