Wheel arch Liner studs
Hi there
I hope someone here can help me. I am currently doing a major bumpers off clean of the car and noticed that I have 2 wheel arch liner studs missing. These are the one's that the wheel arch liner plastic nuts screw onto. They have left a hole (which is now rusty) in the body work :-( - Also I have a similar stud missing from the drivers side plastic side skirt.
I have searched the PET and also asked Porsche for the parts but they say they do not sell them - What can I do??
Thanks in advance

I have just put a M4 x.7 pitch tap through a new Porsche black plastic nut and it was perfect. I think the original studs have a course thread so it looks like they cut their own thread in the plastic nuts.
I would go for tig welding some stainless M4 studding in place. Obviously you need to need to sort the rust out. Sheet steel flush welded perhaps. A good welder will be your friend.

just drill a hole where the stud would be and put a self tapped screw in it. Its not like they are holding on the transmission, its a little piece of plastic.

How rusty? Is the hole still solid or is the sheet metal flaky?
You could install a flat head round body closed end Rivnut which is probably the most elegant non-original installation. You would then screw a threaded M5 or M6 pan head screw into it using a body washer. I'd go stainless.
I always use silicone grease on those studs prior to screwing on the plastic T5 nuts to keep applied torque to a minimum...just so that they do not break off.

There are many, many ways to fix your issue. Its up to you on how you want it done. The posts above are proof of this.
If its a hidden, non-structural application, as we know it is; I am of the belief in the quick, easy, non-invasive approach; and getting on with life.
If there's rust, it should be addressed. Rust spots NEVER get any better...
