*PCA Junior Participation Program (JPP) is intended to encourage families to become and stay more involved with PCA and covers 16 & 17 year old sons, daughters, step-children, nieces, nephews and grandchildren of PCA members.  Once these sons, daughters or other relatives become 18, they will be able to join PCA as a full member.

The JPP allows the above listed fully-licensed 16 & 17 year olds to participate in autocross, autocross schools, gymkhana and rally (as navigator only) club events. All JPP requirements must still be fulfilled, including having the appropriate insurance forms/waivers properly filled out and signed by all parents/legal guardians; and having both at least one parent and the relative that is a PCA member in attendance at the event.

Registration Procedures:

At the gate you will sign both of the "Insurance Releases."

Park your car and register at the trailer.

Return to your car and prepare it for "Tech Inspection." When you and your car are ready for "Tech", open both of your hoods and stay with your car. A Tech Inspector will come to you and complete the "Tech Inspection". If you are new to autocross, empty ALL the contents from your car and trunk(s).

As Redwood Region's past and current Autocross Directors, we would like to invite all Redwood members to come out and visit our autocross events, even if you do not want to compete.

2018 AX Rules

All of Redwood's autocross events will be for PCA members or Porsche owners only. PCA members may drive any vehicle at our autocrosses. All non-Porsche driver participants must show PCA membership card at the gate.

What is autocross?
Autocross is a sport where you try to drive around a course in the shortest possible time. The course is laid out at our wonderful site at the Sonoma County Airport and outlined by orange plastic cones. Every run is timed electronically and time is added for each cone tipped over. You can measure your progress throughout the day, and possibly earn bragging rights. We emphasize safety, fun and speed. This is probably the safest and least expensive way to drive your Porsche at the limit.

Autocross is also a driver education class. If you are completely new to autocrossing we have qualified instructors available at each event at no charge. We also have loaner helmets available.

For those of you who are interested in autocross, but not sure if you want to give it a try, we offer "A Taste of the Autocross", where for $5 we will put you in a car with one of our instructors and let you ride along for a couple of runs. The money goes to our charity, Sonoma CASA.

Autocross is a great way to:
Learn how to handle your Porsche
Drive your Porsche the way it was meant to be driven
Make new friends
See "old" friends
Spend time with your significant other doing something fun
