Street Stock Rules

The Large Tire Street Stocks will be a part of the Trail-Way Speedway Friday night racing series in 2018, under the name, “Street Stocks.”

The Street Stocks that raced at Trail-Way Speedway in 2017 will be allowed and are encouraged to make the proper changes, listed in this set of rules, to upgrade them to the new Street Stock rules package.

If there is a rule that does not match local rule books, it will be in blue.

Please check the rules on a weekly basis throughout the off season. We will color any adjustments and change the date with the same color. There may be periodic rule adjustments to help equalize the competition at the end of each month during the season. Those changes will also be announced on our social media accounts.

The safety/tech inspector and track management will have the final decision on all rules. If you have any questions, please contact us before continuing.

Also, please read the general rules that apply to all divisions.


Just because it isn’t in the rule book, don’t assume it’s legal.
