Thunderhill Raceway Park

About this event


Porsche Club of America Diablo Region Track Day at THUNDERHILL RACEWAY PARK

Sponsored by Porsche Walnut Creek 

 Friday,  September 7, 2018 

5 Mile Track Configuration

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



7/28/18: We are currently wait listing all non-Sponsored Beginner drivers who require an Instructor.  There is no charge to be on the wait list.  If we have additional instructors register we will clear people off of that wait list on a first come/first accepted basis.  Only Beginner drivers who have been cleared to drive solo at Thunderhill should register as "Beginner Cleared to Drive Solo".

8/19/18: Our Beginners group (those who need instruction) is now full.  We can no long accept people on the Beginner's Wait List who are not a Sponsored driver.  If you were already on the Wait List, we are still working out the Instructor list and will have the current Wait List worked out by end of day August 26.

8/27/18: We have now filled all spots for Beginners who need instruction.

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 ( 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.

  • Porsche Walnut Creek – by appt. only
