Recommended battery for 2014 boxster s
READ ANSWERConverting short wheelbase 911 to long wheelbase. I know I need to replace the swb trailing arms with the longer aluminum banana arms and lwb spring plates. I have heard that the pivot points for the banana arms must be relocated? I have also heard they are fine where they are? Also, the upper shock mounts must be moved? If so, can you provide the specs? Thank you for your help.

READ ANSWERon my 2014 Cayman S I've had intermittent power steering loss. Most times only for a moment, but recently completely out with warning on the dash. Shop checked and found code for short/open circuit in the power steering motor. My question; is the power steering motor integrated in to the steering rack where the motor can be replaced or does the entire rack need to be replaced?

READ ANSWERWill regular use of the "stop/start" function reduce the service life of the engine bearings?
Thursday 10/09/2025 | 2016 | Cayman S | Engine
I recently acquired ths car as a CPO. The dealer had the "start/stop" feature turned off when I purchased the car. I've talked to a few other Porsche owners with cars that have this feature, and they, too, have it turned off. In a perfect engineering world Porsche would have beefed up the bearings before the US government required this feature to account for the anticipated additional wear. Did Porsche? I get no particular joy unnecessarily burning fuel at a stop light, but I want this e ...
READ ANSWERMy odometer just stopped working on my 1980 911 SC so I pulled it easily from the dash and sent it to Palo Alto Speedometer company to replace the broken gear. Do you have a diagram of the back or the 150 MPH gauge to make sure I connect the right wires to the right connector? Do you have a recommendation to replace the bulbs with LED warm bright lights?

I’m having trouble installing the front spoiler (photo below). The valence is flexible, so it simply bends upward when I try to push the tabs into the slots. It is the correct part, and the slots all line up. Any tips?

When I activate the fan in the deck lid to stage 1, there is no movement. When I activate it in stage 2, it spins but sounds really rough unlike before. This happened after a 5 hours drive in 80 degrees. I removed the fan and it spins freely.

READ ANSWERHi there - I have had to replace the driver's side convertible top transmission as a result of the plastic drive wheel breaking.
Tuesday 09/30/2025 | 2006 | Boxster S | Other
The installation was straightforward and the top is operational again but since installing the new CT transmission I have notice the passenger side of the clamshell is not flush with the rear quarter panel on that side, while the driver's side is flush. It is quite noticeable when the top is down (the clamshell is about 1/4in above the pax side hind panel when the top is fully retracted - see pic attached) vs when it is up (about 1-2mm above the pax side panel and barely noticeable). The od ...
