2015-2016 ISOC Rulebook Coming Soon
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.
12/29/14: Rebalancing the Stuffing Blocks of the Crankshaft – Please read the details here.
USAC Membership Requirements – All ISOC racers and crew must now become a USAC member due to our change in insurance. Please read the details here.
The Pro Lite drivers running the NATIONAL ACS Circuit as their primary circuit will be allowed to run single and double digit bib numbers. Numbers will be assigned on a first come, first served basis once membership opens September 6, 2014.
We will be STRICTLY enforcing this rule this year. There will be no one allowed on the track if their helmet does not meet the standards set forth in the ISR rulebook above.
