Welcome to Round 4 at Sonoma Raceway!  We will be joined by guest race groups Bill McAnally Racing (BMR) and U.S. Touring Car Championships (USTCC).

IMPORTANT: COVID-19 policies: No in-car instruction for HPDE1.  No passengers in cars on track.  Face masks required.  No spectators allowed.  Four support personnel per driver.  Café is open.  Camping in the paddock is allowed.  Please review the full list of regulations:

  • From our Regional Director, Jerry Kunzman: "There is still a full mask / social distancing mandate in place for this event.  Everyone knows we like to run laid back, low hassle events.  Unfortunately, we have to be super strict with this policy.  It’s not only a matter of public health, but image for us and the raceway.  Masks are required at all times, except: eating/drinking or in your trailer / vehicle.  This includes wearing a mask even when walking by yourself outdoors or working in the garage area.  Hopefully this nightmare will soon be over for all us.  Just don’t make it a bigger nightmare for you by getting excluded from the event for non-compliance.  Thank you."

NO TESTING ON FRIDAY - NO EARLY LOAD-IN ON FRIDAY.  Registered NASA participants and their support personnel can plan to load-in after 6 PM on Friday evening.  Any NASA weekend participants arriving earlier on Friday will be staged in Parking Lot 2 until the track has been vacated at the end of the day.

  See Kaleb at the registration trailer; $150 for the weekend.
