A question came up in a discussion about testing Relays. Relays seem like magical little boxes of wonder. They often catch the blame for mysterious electrical gremlins because they're operation is a mystery to most auto enthusiasts. But if we really stop to learn what a relay is and how it works, we will learn that they are really quite simple. Understanding and being able to test them can help us cross them off the list when things go wrong. So let's take a lesson on Relays, how they work and...

The flexible brake lines that connect the calipers to the brake line hydraulic system are subject to wear and should be replaced periodically. This article provides a guide on how to replace the brake lines on a Cayman. In this article I replace the factory brake lines on my Cayman with new Braided Stainless Steel Brake Lines. Braided Stainless Steel Brake Lines are a relatively inexpensive way to improve the feel of your Cayman's brakes. The intent of braided stainless steel brake lines...

While installing my Fire Extinguisher mount, I found that the procedure needed on my power seats is somewhat different than that needed for mechanical seats. I thought it would be a good idea to highlight and share the differences. NOTICE: This guide is ONLY for the driver's side power seat removal. Passenger seat removal & replacement requires recalibrating the Auto Weight Sensor. I installed the Rennline mount but the specifics on installing this mount will not be discussed since it...

This article describes the installation of three all aluminum radiators made by CSF ( no affiliation ) on my 2007 Cayman 2.7L. The radiators are welded things of beauty which promise to be more rugged than stock radiators and increase cooling capacity by 8 - 10% due to their design. There are three part numbers involved: CSF7047 Left Side Radiator CSF7048 Right Side Radiator CSF7049 Center Radiator Four fresh O rings on the radiator hoses: Two pieces P/N 99610680107 and two pieces...

This article describes the installation of the Vision Motorsports big brake kit for Cayman. Diver Dog had this kit installed previously. The advantages of this kit are ease of pad change, wide selection of pad choices and improved braking. Installation was straight forward, removing the stock calipers and rotors and replacing them with the new 350 mm AP rotors and 2004 GT3 6 piston calipers followed by a brake bleed. The kit consists of two new AP rotors, two new 2004 GT3 front calipers, two...

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...

As many of you know, 987.1 Caymans came with no front or rear brake caliper/rotor cooling ducts. This can be problematic for cars that spend a lot of time on the track. Cooling of the front calipers and rotors can be handled in a very straight forward manner by using 997 GT3 front cooling ducts. The 997 GT3 front cooling ducts are inexpensive and are a drop-in part for the 987.1. The rear cooling duct is a little more complicated, but not too much more. Also, although there are other ways...

Maybe you want to install a fixed Cayman R spoiler, a Cayman Interseries spoiler, or maybe you need to remove your rear bumper cover. Either way, you'll need to remove the electric spoiler first. Here's how.... 1). Raise the rear spoiler by turning on the ignition key and pressing the 'Spoiler' button. 2). Remove all seven T-20 Torx Screws from under the front edge of the spoiler. (I highly recommend a Skew-Driver for this task.)

A clutch slave cylinder should last a long time. But there have been incidents of slave cylinders leaking in Caymans, which can leave your clutch pedal on the floor. There was a Workshop Campaign (W802) back in 2008 to replace more than 1,200 bad slave cylinders that made their ways into cars (987s and 997s). Should you find yourself in need of a new slave cylinder, this article should be of great help to you. 1Torque Values Fastener LocationDescriptionTool SizeTorque ValueClutch...

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...
