General Information

  • Most tracks run a test day on Friday for race cars (not HPDE). To participate, racers register with and pay the track directly. Check the track websites for details.
  • If NASA is offering online registration, that means NASA is operating the test day. Check the NASA SoCal and the NASA websites for information.


Please check the event page for the weekend schedule. The schedule is typically posted few days before the event.


  • You do not need to visit registration unless you are renting a transponder. Simply attend your drivers’ meeting at the time indicated on the schedule.
  • If you have rented a transponder, you can pick that up from registration.


  • Annual Inspection: You must have a current year, annual inspection and valid tech sticker prior to your first race of the season.
    • Review this checklist to determine if your car will pass inspection.
  • Logbook: All cars must have a logbook.
    • Cars without a NASA logbook pay a $40.00 fee for new logbook and inspection.
    • Cars with a NASA logbook pay a $20.00 fee for a current year annual inspection. Annual inspections will be available beginning Saturday at 7am in the impound area. Look for a small trailer near the pit wall.
  • Safety Reminders:
    • All race cars are required to have a side impact net or a seat with head bolsters on the right side. Please see CCR 15.17.9.
    • All racers are required to use a SFI 38.1 approved Head and Neck Restraint (CCR 15.17.8)
    • Helmets must be SA2010 or newer.
  • Event Supplemental Regulations (SUPS) might apply to the event. Please check the event page.


  • Tech Inspection Form: Download and print form.
  • Pre-tech: Any repair shop with an ASE certified mechanic may perform your inspection.
    • Attach business card to form or have them stamp it.
    • Bring tech form (that has been signed by a tech shop) to tech trailer and get a tech sticker.
    • Apply tech sticker to upper left corner of windshield.
    • Attend HPDE drivers meeting at time specified on schedule.

Note: If you have aftermarket seat and/or belts, read the CCR for compliance. Don’t assume an ASE shop reads the rule book; they don’t necessarily know what is legal.

  • Trackside Tech
    • Bring your car to the tech trailer for inspection by 7:00 AM.
    • We will inspect the car, sign the tech form, and give you a tech sticker.
    • Put your tech sticker on your car before you line up in pre-grid.
  • Car Numbers: HPDE cars need a 3-digit number affixed to both sides of car. Blue painter’s tape works great. Choose a combination of 3 different digits (example# 157) to prevent duplication. TT may use 2-digit numbers.
  • Roll Protection: Convertibles require roll protection (CCR 11.4.7) Some vehicles with OEM roll protection are permitted (S2K, Boxster,).
  • No Passengers: Regional rules do not allow passengers in convertibles in any group or in HPDE 1&2.


Check the schedule on the event page and report to your meeting on time.

Group leaders take attendance and distribute wrist bands at the drivers’ meetings.
