Back at Sonoma! We are joined by USTCC.


If you do not see the HPDE Group that you want, it means that it's full.  If you are unsure of which HPDE level to choose, please use this handy tool: HPDE Survey

HPDE / TT Groupings for this event:


- HPDE 1 & 2
- HPDE 3
- HPDE 4
- TT


- HPDE 1 & 2
- HPDE 3
- HPDE 4

Do not choose "instructor" below. One will be assigned to you automatically.


HPDE 2 is for drivers that have been signed off to drive on their own, but just want more time in HPDE 1. So, Group 2 is Group 1 (and runs with Group 1), but they have no instructor assignment. Please see this notice before signing up


There will be at least four 20-minute sessions. Please see the prerequisite page to make sure you are eligible.
Sunday only entrants MUST have completed a prior Sunday HPDE3 event to be eligible.


There will be at least four 20-minute sessions. Please see the prerequisite page to make sure you are eligible.



All regular NASA race groups: AI, AIX, CMC, FFC, GTS, PRC, PT, ST, HC, NP01, SM, SI, ST, STR, SU, SpecE30, SE46, SpecZ, Pro, Semi-Pro, Thunder Roadster.


Spec Miata/SE30 drivers may Supersize


There is a ~4 Hour endurance race, including warmup.  Please see the new classing based mostly on Super Touring mapping.  Virtually any vehicle can enter, they just need to use the calculator (soon to be linked here) to convert to an endurance class.  Note- ST1 and ST2 have been mapped to ES.  ST rules require submission of a classification form.  IF YOU ARE ENTERING ES AND MEET THE ST1 OR ST2 RULES (mostly wide open), then Nor Cal does not require the submission of a classification form.  Furthermore, any "SU" vehicle entering ESR does not need to do anything else either, but enter.  Again, if you enter ES or ESR, you do not need to submit a classification form.  It's simple.  Just enter.  Endurance race is part of the WERC points series and the drop-down entry will be added shortly.



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.



Your car must be tech'd before going on track.

There is a $10 fee per person per event at the gate (Keep your stub for the weekend).


HPDE/School/Open Track: Full refund less $30.00 processing fee, with at least 1 week notice prior to the event, otherwise no refunds or credits. No exceptions.

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.
