Any Questions about the Enduro can be directed to Scott at the NASA NorCal office.



There is a STRICT sound limit of 101 dBA measured 50’ from the line on driver’s right, apex of T12.  Attempts to fool the meter or lift will easily be detected by the track’s dedicated sound person (they hate that!).  So, please prepare to adjust your muffling system if necessary.  This is the same standard that has been in place for years.



Race Groups: Fees are fully refundable, less a $30 processing fee, provided that you registered at least 12 days in advance and you notify your NASA region within 5 days following the missed event. No partial refunds allowed. This policy does not apply to special events. Once the car hits the track all fees are non refundable.



Registration is closed for this event!
