Here is a video of PCA Zone 2 DE.
Here is a video with a novice driver at Putnam Park. You can hear some of the conversation with the instructor.
Now that you are interested, what next? There is one piece of safety equipment you must have before going to a DE: A Snell SA helmet with one of the last 2 ratings. This is not a motorcycle helmet, and there is a big difference. Snell SA helmets are made for in-car use and contain fire retardants that motorcycle helmets do not have, as well as several other differences. SNELL is a standards organization, not a manufacturer. Helmets with their ratings are made by many helmet manufacturers. This year (2018) you can enter all DE's with a Snell SA2015 helmet. Most events will also accept SA2010 helmets as well. These helmets are available from many distributors such as Hoerr Racing (near Peoria), Summit Racing, Jegs, and many others. You can get them from around $250 and up but if you are buying one now, get the SA2015. Some are still trying to sell the SA2010 helmets so be careful. Some events do offer helmet rentals as well.
There are many DE events at the various tracks near us. Here is a map of those tracks. For us the Chicago, Central Indiana, and St. Louis regions of the PCA have some great nearby events. One of the best tracks and events for beginners is the CIRPCA Spring Break at Putnam Park. This track is particularly well suited to getting started as it tends to be more forgiving than most. CIRPCA has this website of great info on DEs. Chicago region also holds a DE at Blackhawk that is often focused on novice DE drivers. Most PCA regions, as well as many other car clubs, use Clubregistration.net or MotorsportsReg.com for their events. You can search there to find events.
Your normal car insurance will likely not cover you at the track. There is special insurance available for these events though. The PCA recommends Lockton Motorsports and there are others.
Here is what to expect from your first track day. Before the event you will need to have your car inspected and an inspection sheet filled out and signed. Basically your car must be in good condition with no leaks, good brakes and tires, seat belts in good condition, battery properly mounted and terminals protected, etc. You must also flush your brake fluid with high performance brake fluid within 30 days of each event. When you check in to the event, they will often do a quick check as well. The morning of the track day will begin with a mandatory drivers meeting. You will have a schedule for the day which includes both classroom instruction and 25 minute driving sessions with an instructor. Generally you will get 4 sessions per day. The in-car instructor at a PCA DE is a person who is an advanced driver and has passed the PCA instructors program.
DEs are a great way to experience your Porsche in its natural habitat doing what it was made to do. Its not for everyone but it is very fun for those who want to experience their Porsche doing what it does best. You drive at a pace you are in control and comfortable with.
