As many are probably aware,
Porsche
revised the shift cables and the 1-6 gear cable (driver's side cable) support on the transmission and the pivot lever that attaches to the shift rod on the transmission. These support and pivot lever revisions did two things, 1) improve the angle of the support at which the cable mounts to reduce stress and the potential of snapping and 2) address all the slop pivot lever that occurs as the rubber bushings in the pivot lever begin to degrade. See the images below of the original pivot lever fully disassembled. There are four bushings total that sandwich inside the lever. As these bushing wear, it create 1-2 mm of internal movement which translate to about 1/4" movement at the shift knob.
The revised pivot lever is a solid piece of metal now. It basically looks to me like Porsche took the original pivot lever parts and welded them together. With the all metal pivot lever, the shift action is very mechanical and connected.
The Numeric cables do nothing to address the issue with original pivot lever. It was my my understanding, that the Numeric cables are not compatible with the new pivot lever. After some studying and comparing, I really can't see any change in the design and why the revised pivot lever wouldn't work with the Numerics. Alternatively, one could possibly make the original a solid piece by disassembling it, removing the rubber bushing, cleaning it up really well, adding some JB Weld into the voids left by the bushing, thus creating a solid pivot.
I still have my old disassembled pivot lever in case someone wants to give this mod a shot without modding their own. I just ask for a few bucks for shipping. PM me if you're interested in trying this mod.
Here is a DIY to show you how to get the pivot lever off the tranny.
Outstanding Tech Contribution! - FYI helpful pointers...
During Christmas break I replaced the heavily worn, original shift cables in my recently acquired 2011 Cayman Base with 70K miles. How the OEM cables lasted this long is a mystery, but shift feel was terrible and the shifter wobbled around even after I adjusted the cables and installed metal...

As long as the ball joints remain in the same position, there's no reason this wouldn't work with Numerics.
I remember reading (here, I think) of someone fixing this problem by replacing the rubber nubs with delrin rod of the same diameter.
So, I am new to 987's, and am looking into getting the
numeric shifter
. Is this set of updated parts for the shift-lever side of the system? Or another part?
Would one benefit with these updated parts AND a
numeric shifter
? Am I just over-complicating things?
I don't have the Numeric shifter, but it is a direct replacement for the stock as far as attachment goes. The updated OEM parts are only at the transmission end. So it doesn't matter which shifter you use. Of course, to upgrade your cables, you'll need to have access to the shifter (center console removed) so it is an ideal time to upgrade your shifter.

I would like to take your offer of your pivot lever but can’t figure out how to PM you.If it is still available PM me. My email is in my profile account.Thanks.
PM = "Message" if you hover over the username on the website (not sure if this works on mobile or other platforms). Alternatively, you should be able to click the user's name, and then message them via the "Start Conversation" link.

Is there any concern that removing some of the damping in the shift action could wear on the synchronizers more? I do not outright doubt
porsche
- but I also do not want to have to plan for a transmission rebuild.
This feels weird to even ask about as I bang on my ZF5 all day in my track toy E36 with solid everything. But those transmissions are "only" $600.
It's pretty clear to me that the rubber bushing in the original pivot lever was to reduce linkage noise and perhaps some vibration through the shifter assembly. I do not see any reason why it would create a synchronizer issue. If anything, I think it could slightly reduce synchronizer wear as the shift action is more direct, thus reducing the chances of not fully entering the gear detent and causing a grind.
What about all the
Numeric cable
owners who would like to upgrade the original pivot to the new style. Is that possible as the steel cables put more strain on the old pivot than the new OEM cables? Or as Racergreg suggests in #2, just replace the old nibs with delrin rod of the same diameter.
