Entry Fee: Must be received one week prior to event to qualify for the pre-registration deadline

Line up:All pre-registered cars will be included in a random drawing to determine the starting lineup.  Non-preregistered cars will be lined

up behind the pre-registered grid in the order they pass tech.  Cars that have not successfully passed tech 1 hour before the scheduled

start time lose their starting position. 

Scoring:Transponder scoring is used at ISS events.  You can supply a working AMB 260 transponder, or one can be rented (for $10)

at the event.  Non pre-registered cars receive rental units on a first come, first served basis.

Penalties:    Cars not passing pre-race tech will be assessed any number of penalty laps at the start of the race.
