PDK shift direction
Just an interesting thing to note. I remember reading an article by Evo magazine that explained the theory behind pulling for upshifts vs. pushing for downshifts. Race/rally drivers all have their sequential transmission shifters set up to allow upshifts when pulling the shifter, and downshifts when pushing; it's infinitely easier to throw a hand out and "hit" the shifter forward during hard braking, while it takes just a bit more effort to reach out and pull the level back toward you. It basically lets you get your hands off (and back onto) the steering wheel a fraction of a second quicker, and simultaneously allows you give it less thought while braking hard into a corner.
It makes sense if you think about it.

Not.
He shifts only with the paddles and takes his left hand off the wheel only to scratch his nose or adjust his glasses.
I assume most of you know how hot a 7:37.9 on the Nordschleif is? Sounds like the above EVO magazine theory could be a "journalist's" solution in search of a problem that doesn't exist.
Yeah. During his 7:37.9 lap of the Nordschleif in a 991S PDK, watch how many times Porsche test driver Timo Kluck reaches down to the shifter with his right hand. Or how his body lurches forward during heavy braking.

Right... except your entire argument here is based on a lap in a street-spec 991S equipped with a PDK lever, as well as steering wheel paddles. Pay attention to my post, where I mention "race/rally cars with sequential transmissions." If you didn't know, most older (and even current) rally cars (and quite a few road racing cars) I mentioned only had/have a single shifter sticking out toward the driver; no paddles. Hence, it's a different story.
I'll make sure to tell these "journalists" what you think, though.

We can beat around the bush as long as we want. Fact is, compared to the de facto standard, Porsche has got it wrong in the Carrera. I hope they will rectify it like they did in the GT3. And while they're at it, they can place the paddles on the steering column too, instead of on the steering wheel !
2 minor changes, and we're back on track with how every racecar on this planet does it ! Come on Porsche. I'm holding on to my C2 until you fix this ;-)

The paddles switch gears electrically. It's just two contact closures.
I would assume the very same is true for the stick - it does not row any gears - it just closes one of two contacts depending which way you push.
That should mean it could be as simple as swapping two wires to get this fixed (if you don't mind the "+" and "-" symbols staying where they are).
Would be nice to have access to a workshop manual to find out...

My bigger issue is with the direction of the shift lever action then the columns on the wheels.
On the street I rarely use the paddles and even out on track since my mind is somewhat hardwired for a manual I find myself using the lever instead of the paddles.
When you are braking into a 2nd gear corner from 130mph pushing back on the lever to drop down gears is just counter intuitive.
Guess I need a GT3.

IIRC the same exact situation played out with BMWs and their Steptronic 5 series in the 2000s vis a vis the pull and push gear changes. Like now, some defended the "wrong" way (which is how all 991s except GT3 are set up) but then BMW reversed the direction and then those defenders were nowhere to be found subsequently.
In that instance the 5 series owners did find a way to switch the + and - leads so that the shifter worked "correctly" - so it may be possible to do the same with PDK. I find paddles much more ergonomic anyways so it really doesn't bother me.

By the way, when I'm in strapped into a 5-point harness, my body does not move. Period. Kluck just has the standard diagonal seat belt. I really don't understand what they mean or why it's a problem for them.
Don't know how to make the Roll Eyes symbol like you, but it's implied.

Every Porsche race car (and probably every race car) with sequential shifting is “pull back for upshift”. Why they decided is change that for their street cars is bewildering.
Sure you can use the paddles but sometimes I like the shifter (even with it being backwards).
So to get back on track. Is there a “fix” to this issue of backwards shifter?

Please do. Also ask them to explain Kluck's body not lurching forward and back like they claim it should, which blows their theory away. Or, maybe he's just smoother than they are in their 6 year-old Mazdas, perhaps, and because they're lurching all over the place they think that's the way it should be for everyone/every car?

Secondly, what's with the exaggerated remarks and random low blows in your posts? Where did anyone ever mention Evo having "problems" with the setup? And who drives the 6-year old Mazdas? Their editors who own Zondas and GT3s? I simply posted Evo's explanation regarding something that MANY enthusiasts discuss. If I remember correctly, their "theory" (which they addressed in a single paragraph) was based on interviews with heads of a couple of small, unknown auto brands that have absolutely no racing experience. One of them may have been "BMW," but I've never heard of them.

Bottom line: This technology was not implemented in 2013. Decades have gone by since race drivers experienced this type of transmission in a car. You can throw out Kluck's laps and modern-day iterations of this technology all you want, but it doesn't apply.
Oh, and just for some giggles, here's an amazing video of a GT3 on a rainy, slippery, dirty rally track. As you can see, even this car is equipped with a sequential transmission that uses the "pull to upshift, push to downshift" setup. Watch the entire video:
There are plenty of occasions where Ruben literally "throws" his open-palm right hand onto the shifter and pushes the level forward without having to think about it, especially when he has to tame a wet track with a shift lever and an e-brake lever, all while grabbing the steering wheel immediately afterwards to correct oversteer. Sure, if the design were the other way around, one would get "used to it." But this, in my (and many other people's) opinion, is easier and more intuitive.

Which is why I linked the video of Kluck in a .......... 991S. Same car, but no lurching as promised by the "experts".
You're the one trying to turn this into a discussion of rallye and race cars of yesterday's lore. Reading comprehension, please.
I notice from your signature that you have a 7MT. But you sure spend a lot of time on this forum trashing the PDK shift lever. Why? Most people would be smugly ... or confidently, at least...happy with their choice.

But I need to be more tolerant. I'm sorry.
