Hello from TOP-GT! TOP-GT mostly host track day events at Laguna Seca, Sonoma, and Thunderhill. We will also visit South California a few times a year! TOP-GT is aiming at creating a friendly and relaxed environment for people to pursue speed and learn techniques. We want everyone in our event:

  • Drive Safe!
  • Have Fun!
  • Make Friends!

TOP-GT is not a race event, but many of our drivers and staff hold racing licenses and are willing to share their knowledge and help everyone to improve their lap time or learn how to drive safely. To better serve people's needs, TOP-GT's event usually allows a limited number of drivers per day and provides much more seat time comparing to other events. A typical event will provide 100 minutes of seat time and skid pad (unlimited use) if it is available at the track.

We will follow COVID-19 protocols and regulations from the local county and require everyone:

  • Passengers are allowed at this event. No pets allowed. No exceptions.
  • All participants must wear a face mask (non-venting) in all public areas, such as driver registration, meetings, garages, food lines, and track viewing areas. Masks are not required while in vehicles.
  • Social distancing is recommended in all areas - 6 feet or more between people
  • Participants who are sick or coughing should not attend and will be required to leave.
  • Non-contact thermometers will be used to check body temperature and participants will be required to leave if fever is detected.
  • We will minimize contact during the check-in process as much as possible.
  • Garage rental is not available at this track.
