Monday, November 23, 2020

Limited size run groups, lots of track space, tons of track time

"Have Fun, Be Safe, Drive Fast"

THIS EVENT IS FOR PORSCHE CARS ONLY - All event details can be found at



General Event Information:

This event is open to all Porsche drivers who have been cleared to drive solo on Thunderhill Raceway.  Drivers who have been cleared to solo at other tracks, but not Thunderhill Raceway, will be considered for this event, based on the review by our Chief Driving Instructor.

We are a Porsche club, not a driving school or a driving business.  We run several safe, fun and friendly track events each year. We do not race, time trial or time laps. We limit this event to 25 cars per run group so that we can offer plenty of room on track and lots of track time. 

We expect to run three run groups: Beginner Solo, Intermediate, and Advanced.  The DE team will review all registered drivers and will confirm the run group classification for each driver based on overall track experience.  During the event the DE team will work to accommodate drivers wishing to change run groups, subject to approval by our Chief Driving Instructor (CDI).  

COVID-19 Related Changes:

Due to Covid-19 restrictions and requirements, this event will be run differently than past Diablo PCA DE events:

  • We are unable to provide in-car instruction due to COVID-19 social distancing requirements.
  • As a result, this event is only open to people who have been CLEARED TO DRIVE SOLO on Thunderhill Raceway PRIOR to registering for this event. Drivers who have been cleared to solo at other tracks, but not Thunderhill Raceway, will be considered for this event, based on the review by our Chief Driving Instructor. No first time DE drivers. 
  • There is also no special registration option/discount for Instructors because we are not providing instruction.  
  • Some event details, such as the DE 101/201 class, meals at the event, and general event logistics, will be communicated to registered participants as we get closer to the event date.
  • All drivers,  crew members, and guest will need to read, fill out and sign several documents that will need to be emailed back before this event, or brought to this event already signed.  You will receive an email just about 1 week before the event with details about those forms.

We appreciate your understanding and cooperation.

Private Instructors/Coaches:

Private instructors/coaches are not allowed at this event. 

Passing will be with mandatory point-by in all groups:

We take safety very seriously, and will “black flag” any participant who disregards passing protocols or consistently fails to give point by's, including denying access to the track with no refund of registration fees if deemed necessary by the safety officer.
