I see at least four different options for the replacement latch liners, apparently from different materials on each.
Between 928 Motorsports, 928sRus, Jager Engineering, and 928 International, and then the random eBay offerings that I'm not even considering.

Is there any particular advantage of one or another for specific applications?

These are the ones that I saw, but who knows which others might also exist.

Any clarification would be welcome.



Impatient tinkerer edit:
I arbitrarily picked one, and bought the 928 Motorsports offering that looks much like the original part.
I'm still curious as to what difference, if any, the various materials or design tweaks might make.

 

Very little difference at all apart from Quality and price. Original was/is white with a yellow tinge which turns opaque with age and use.
Recently Porsche has been shipping the lower hatch receivers without the insert at all. Suffice to say the ones we received were returned but I do not know if the issue has been rectified.
So apart from color they probably all do the job as stated. They center the male into the female and attenuate some movement.We have sold nearly 3000 over the last 12 years with zero issues. Adjustment is made on the lower latch assemble.
