2015 Rules
The rules package put forth at the beginning of the 2014 season is valid for three years, 2014-2016. This was done at the majority of the racers requests to have a rule package that doesn’t vary, so that you don’t have to alter your cars and spend valued resources to be legal.

In addition, track management has listened to the majority of racers who desire more clarification of the current rules. So, that’s what we are doing by giving the racers the “more clarification” that they have asked for.

The most notable things you are going to see in the clarified 2015 Rules are:
-Structure and uniformity to the written rules from class to class, which makes the rule book easier to follow for racers and officials.
-Deletion of redundant rules.
-Deletion and clarification of contradicting rules.
-Rules that may encourage non-local racers to race with us and further our car-count going forward.

Therefore, build your cars or repair your cars based on the current 3-year rules that you requested. If the rules say you were allowed to do XYZ in 2014 but NOT in 2015, that still applies to the written rules.

As you can see, we are listening to you, the racers, in balancing your requests. We look forward to a great 2015 racing season.

Thank you,
I-25 Speedway staff
