I'm reasonably certain these are installed either at the port or at the dealer to address a design flaw with the belt locks rubbing against the center console when someone with, say, more than a 35-inch waist or so sits in the car. I say this for three reasons:
- I have two different types on mine -- and, like
@JakiChan, the one with the larger area of coverage is on the passenger side, which makes little sense since it's used far less frequently.
- The installation is not precise; they basically look slapped on.
- Mine have not peeled off like those on the car that
@autobahn has, even though I live in the same general area he does. That, in addition to reason #2 above, leads me to believe that different pads are used by different installers in different places.
@JakiChan and others with 'official' Porsche connections: It might be worth inquiring about where these are installed. It's obvious to me why; the question is when, and by whom.
