About this event

 IN-CAR instruction will be allowed HPDE1.  Passengers allowed!  Spectators allowed!  Café is open.  Camping in the paddock is allowed.

FRIDAY TESTING AVAILABLE!  Discount for NASA members!  Use the code NORCAL to get $25 off your testing day entry.  Register directly through this link:

  HPDE 3 level drivers and higher, supersize into the OPEN TRACK sessions and double your track time!  For drivers already registered for another run group, supersize into OPEN TRACK by scrolling down and selecting the "Open Track - NASA Members" option.  

OPEN TRACK is also available a la carte to HPDE 3 drivers and higher who are not registered in another run group.  Scroll down and select the "Open Track" option to register.
