At some point during your development as a track driver you will want to find a way to measure your progress and collect data to analyze your driving. Early lap timers sensed a beacon placed along trackside to measure lap time. Sophisticated data systems used a variety of sensors placed on the engine and chassis to gather data. Today there is a large selection of devices using only GPS to gather lap times and, knowing speed and location, calculate lateral and longitudinal G-Force. ...

The Cayman and the Boxster share the same chassis. One of the benefits of this is that the Cayman chassis includes the factory mounts used for the Boxster Roll Over Hoops. I believe that using the factory mounts is superior to bolting a roll bar to the floor. The Hergesheimer and new GMG roll bars use the factory mounts. I'm using the Hergesheimer bar but this article will also apply to the GMG bar. The Hergesheimer roll bar includes an all welded main hoop with a diagonal and harness...

I purchased the Aerokit Front Splitters (2006 - 2008 987.1) from Suncoast to complement the Getty R/S rear wing that I had installed earlier. I received the LH and RH splitter, 6 expansion rivets, and an adhesive kit. No instructions were included but I contacted Suncoast and they emailed a PDF file of the Tequipment Aerokit Installations Instructions. This 19 page document primarily covers the installation of the rear wing but pages 17 & 18 cover the front splitters. The splitters...

The Cayman, as delivered from the factory, is one of the world's best handling sports cars but, like all road cars, has had some compromises in its suspension. When Porsche introduced models with enhanced performance such as the Cayman R and Boxster Spyder, suspension modifications were part of the package. Lower ride heights and higher anti-roll bar and spring rates were used in these models. The new X73 Sport Suspension option now available on 981 models includes those same changes. This...

The Getty Cayman RS Wing is a smaller version of the wing used on the GT3 RS. It is an anhedral wing design. The leading edge tips are lower that the center section. This allows a lower angle of attack for the center section which is running in the air flowing down the back of the rear hatch. The ends are running in a more direct air flow and are at a greater angle of attack. Getty built the aero components for the Cayman Interseries race cars and I like their proven wing base. I placed...

I installed my RSS harness bar this past weekend. I like the structural design of this bar because its base plates mount directly to the body under the reverse lever using the factory hardware. There is also provision for the long leg of the reverse lever to go through the base plate into the body, adding more shear strength. If you look at the first attached photo, the reverse lever 10 x 25 bolt goes through the slotted hole. The leg of the lever goes through the large round hole. The two...

You may have heard how much fun, and possibly addictive, our Drivers Education program can be and have decided to give it a try. I’ve recently returned to the track after an extended absence and in conversations with other students have found that a better understanding of tire pressure could be helpful. Our Drivers Ed manual addresses various brake fluids and pads but I have added some detail about specific fluids and boiling points as well as some pad choice considerations. 4 Tire...

After attending your first autocross or driver’s education event, it’s likely that you’ll be thinking about improving your car’s handling. During discussions with other drivers and “interested spectators” you might be advised to get a “track” alignment or find a way to get “more negative camber”. This article will explain what the alignment parameters of toe, camber, and caster mean and how changes in their settings may affect performance. Finally, I’ll discuss the benefits of having a wheel...
