2014-2015 RULEBOOK NOW POSTED – (Updated 2/28/2015)

2014-2015 ISR Rulebook



Be sure to check back for updates periodically. It is up to you to be aware of rule changes posted here.


1. Safety tech in staging every morning. Top three to tech after every round. If you skip tech, you may get a penalty or DQ.

2. Transponders at the National are mandatory. If you race without one, you will be scored last in your heat.

3. Late Entries – Due to an ever increasing number of “late entries” or registrations at the track, we will be sticking to our Late Fee of $25 per class for any entries done after the registration deadline. Online registration closes the day prior to the weekend of the event.


3/3/15:  Update on Transition for the 2015-2016 season.
