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...

One issue with the Cayman is the reflection of the upper dash in the windshield. If you haven’t noticed, stop reading now and don’t think about it again. It is naturally more pronounced with the lighter, sand beige, interior than darker colors. I found that swapping the forward most sand beige parts of the upper dash, called defroster trim, for black doesn’t completely eliminate reflections but does reduce them considerably. Parts are: left defroster trim 997 552 175 01 ...

This article describes the installation of a new master cylinder. Thanks to Rob VN for the pictures. GT3 MC Part #: 99735591030 Note you can buy either the TRW MC or the Porsche MC. Both of these are the same but the TRW cost over $100. 1) Remove the plastic around the master cylinder (MC) by removing the 8 torx screws and jiggling it out.

Let's face it, there are times when you just can't prevent the installation of a front license plate, which unfortunately comes with irreversible damage to the nose of your car. For me, it was tourist delivery that made it necessary for my front bumper to be drilled. This wouldn't be so bad if they didn't just blow screws into the plastic, but that's what they do, and the tension from those screws distorts the plastic around the hole into a volcano like head. Lucky for us, there are Bumper...

Topeak Mega Morph Folding Floor Pump I use a floor pump in the garage to inflate car tires. Call me a Luddite, but I prefer the speed, mechanical directness, exercise and lack of noise a floor pump offers. For adjusting pressures at the track and as part of my emergency kit (see also my article on carrying a spare tire in this section) I always take a smaller version with me on the road. Recently I found this pump (PICTURE 1) which folds flatter and takes up less space than the...

This article describes the installation of an electric power steering pump kit into my 2007 Cayman 2.7L. The GSR Autosport Electric Power Steering pump kit I chose ( no affiliation ) allows replacement of the engine mounted power steering pump and lines with a Porsche Motorsport electric pump and new hose set. GSR Autosport is now Trinity and no longer stocks this kit. Reports are the pump can be purchased from Achilles and RS1. BILT Racing ( no affiliation ) also sells an electric PS pump...

Shown on 5 speed 987.1. I cut a 1 3/4 inch access hole in the plate under the trans axle to easily get to the drain plug. The other thing to note is the 6 speed trans axle gets filled to the bottom of the fill port while the 5 speed transmission requires the level to be diabolically set lower than the fill port by 11 mm. The five speed drain plug requires a special 16 mm triple square anti tamper socket I got from Pelican Parts. The six speed drain plugs are more rational, using 10 mm hex...

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. ...

I was bitten by the track bug at my very first DE experience, and have become something of a track junkie, needing my monthly fix at the track. As I have gotten faster, I have felt the need to add track seats and harnesses in order to hold me in place better. Without getting into the whole debate about the pros/cons of track seats and harnesses, with or without a rollbar, I decided that if I personally was going that route, I wanted some additional rollover protection. At the time of this...

Not long after starting my DE addiction, I started hearing stories of Cayman owners who had problems with the power steering system overheating at track events. In an effort to avoid this fate, I took a look at what could be done to improve cooling with a minimum of effort and expense. The stock power steering cooler is a length of metal tubing under the car. This is very similar in size to the cooler on my Audi S4. The difference is that the Audi has the cooler loop behind the grille of...
