Fender Liners - Incorrectly Numbered Parts
I installed new speed nuts and screws while having had the rear fender liners out of my car. I ordered the parts as per the current Porsche parts catalog.
According to the parts that were in place as well as common sense, speed nut (item 5) should really be speed nut (item 10) on the rear fender liners (where the fender halves join) in the Porsche parts diagram. Item 10 is the type of speed nut with a protective metal shield that prevents the end of the screw from making contact with an adjacent part...like your inner fender, especially the screw closest to the wheel opening where there is less clearance between the fender liner and fender.
This also requires the correct combination screw which should be a B 4,2 x 13 sort of like item 7 which is the correct screw, but missing a built-in washer (which is why they call them combination screws, I guess). I found a replacement elsewhere in the parts catalog which I have yet to order to verify if it is correct. PN: 900 143 177 02, combination tapping screw B 4,2 x 13.

Hi Alex, four years on, and here is a response!
I just had all my fender liners off for cleaning and have reinstalled them. Upon installation, I happened to notice that some of the combi screws were longer than others, which lead me to your post. Yes, someone at Porsche did not have a head for details the day they did this on the PET!
On my car I have 15 screws per side to hold up the fender liners, so 30 total. Of the 30, 22 are the shorter combi screws, 6 are the longer combi screws, and 2 are even longer regular head screws without a washer. The latter 2 go in the rear-most liner position attaching the leading edge of the bumper cover, to the fender liner, to the speed nut attached to the bumper cover support tube. I used the 6 long combi screws on the rear fender liners, but NOT including the where the two halves join. Per side, I put two of the long ones by the rear jacking points and the third one at the rear upper bumper cover support tube. I could not see why these positions would need longer combi screws, but my long combi screws came off the rear, and I figured in these positions they would do not harm.
Not that any of this is overly exciting, but the last thing anybody wants is to put a screw through their fender by using the longer screws there, with the wrong speed nut.

Thanks to the OP for pointing out the correct part numbers.

Some also had the annoying rattle at speed because the speed nut/screw would resonate against the body. I solved that with a couple of strips of closed cell foam placed at those locations on the inner surface of the fender.
