THIS EVENT IS FOR PORSCHE CARS ONLY - All event details can be found at www.diablo-de.org




  • 7/24/19: Porsche Livermore tech inspections added

General Information:

This event is open to all Porsche drivers from first time beginners through advanced level track drivers. We expect to run four run groups: Beginner, Intermediate, Advanced and Instructors.  The DE team will review all registered drivers and will confirm the run group classification of all drivers 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).  Instructors will be allocated to all 'first time' drivers to the track.

Please note that if you intend to share one car with two different drivers, BOTH drivers need to register separately, pay the registration fee, AND be capable of running in different run groups.  That is, both drivers cannot drive in the same run group.  No passengers or guests allowed in cars during hot lap sessions.   If we do offer a parade lap session during this event, passengers will be allowed at that time.

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. (Fortunately, in 9 years we have hardly ever had this happen because, as a limited sized group, we have a chance get to know each other and conga lines rarely happen!).

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. The registration fee includes a full yummy lunch and bottled water throughout the day.

Safety Inspection Information:

All drivers must certify that their car has passed a safety inspection by an authorized person within 30 days of this event per PCA guidelines.  The safety inspection form can be downloaded at (http://www.diablo-de.org/home.html). All drivers will complete this safety inspection form which verifies the condition of their car is ready for the track and will be handed to us at check-in, or at 'grid tech', which is final inspection of your car on the day of the event. Well maintained Porsches should have no problem passing tech inspection, if they have good brakes, tires, no oil leaks and no defects. If in doubt, have the experts look at your car.

The following sponsors are offering free safety inspections for participants of this event:


Private Instructors/Coaches:

Private instructors/coaches are welcome to attend our events once approved by our Chief Driving Instructor (CDI).  If you are bringing a coach to provide you instruction, please be aware that your instructor will need to:

  1. Contact our CDI to discuss their participation and obtain approval. 
  2. Need to register on MSR as an ‘Instructing Only’ instructor, and also list your name in the ‘Are You Sharing a Car’ section of their registration form.
  3. Will not drive their own cars on the track (unless they have registered as a participant and pay the participant fee).
  4. Adhere to all Diablo PCA and track operator requirements

Private instructors/coaches who show up at the day of the event without following the pre-registration requirements are not guaranteed to participate in this event.  Please contact the CDI if you have any questions.

Pre-Event Activities:

DE 101/201: Drivers are invited (strongly recommended) to attend our DE Introduction briefing called DE 101. We will have a section for new drivers to track, as well as discussion on driving Thunderhill, an opportunity to share experience for all levels.   This DE 101 event will be on held on Thursday, August 22 at Pavlo’s Pizza and Pasta located at 2408 Twin Creeks Dr, San Ramon, CA 94583.  Meeting starts at 6:00pm.


Dinner: The always popular and fun no-host group dinner and participant check-in will be Thursday night September 5, 2019 at Casa Ramos in Willows beginning at 6:00pm.  Bring your guests to dinner as well, it's always a good time.  The registration form will ask if you are planning to attend this no-host dinner.  This is for headcount reasons and is not a commitment.

Run Group Selection:

  • Drivers with 5 or less track days experience should register as Beginners (Yellow Group)  

  • Drivers with less than 19 track days should register as Beginners or Intermediate (Yellow Group or Green Group) 

  • Drivers with 20 or more track days or Instructor experience can register as Advanced (Blue Group)

Note: If you are a Beginner, but have been cleared to drive on the track without an Instructor, please select the Beginners-Solo run group.



Registration Fee: $350 per driver 

Registration fee includes a lunch.  Guests can also purchase a lunch ticket at the event 

Instructors driving their cars are $100.  Instructors who are only instructing and not driving their own car on track are free.

Refunds are subject to a $75 cancelation fee.  Sorry, no refunds after August 25, 2019. 

Registration will close when driver count is reached, or on midnight September 4, 2019.
