This thread never fails for some good laughs and going wildly off topic!

To the guys that took delivery on the cars (and yes I have used the search button and can only find the 981 ratios etc)

(1) Gear ratios please and
(2) final reduction ratio and
(3) if the same as current model has third been strengthend
(4) or is it something totally different that wont see the light of day in the street car

"Expectedly, Porsche did include its best gear for the 718 GT4 Clubsport. The racing-spec, six-speed PDK transmission comes with a reinforced dual mass flywheel that sends power to the rear wheels. It is suspended on Porsche rigid mounts eliminating any movement and ensuring perfect weight balance. Its electronic unit is precisely calibrated for racing purposes, while the transmission also boasts internal pressure oil lubrication with active oil cooling. It’s a small work of art this transmission really. Crafted to work for extended periods of time and to provide seamless and strikingly fast shifts. It sends the power to the rear wheels via a specially crafted limited slip differential tailored for racing applications."

Still nothing about ratios and final drive ratio

"The 2019 Porsche 718 Cayman GT4 Cayman GT4 Clubsport Competition Model is for Professional Drivers".
"The 2019 Porsche 718 Cayman GT4 Clubsport Competiton is Tailored for Amateur Drivers"

Had to laugh at the above quotes - such a narrow view of the world and what constitutes competition and indeed motorsport in general. Seat time, age and tires, seat time, age and tires, seat time, age and tires, seat time, age and tires . These are the factors that determine how fast you go, what time you lay down and what you do or do not hit

In terms of numbers of cars and drivers, amateur motorsport dwarfs professional motorsport which wouldn't even exist in meaningful form without the grass roots.

That issue was with the manual in the street version. The CSs all have PDK which wasn't affected by this.

Fair enough, however we don't know the gear ratios as no one is coughing them up.

So lets try this 718 PDK - which can cope with 430Nm
1-3.91
2-2.29
3-1.65
4-1.3
5-1.08
6-0.88
7-0.62
F-3.62

Its all in the final reduction e.g. GT3 PDK 3.97

For equivalent sized wheels and tires - force at single rear wheel

981 GT4 Manual 3.89 fin red, 3rd gear 1.41, force at contact patch (425Nm peak torque) = 3,364
718 PDK 3.62 fin red, 3rd gear 1.65, force at contact patch (425Nm peak torque) = 3,674 (10% improvement over the above)
718 PDK 3.97 fin red, 3rd gear 1.65, force at contact patch (425Nm peak torque) = 4,029 (using the GT3 final reduction - 16% improvement over the manual)
718 PDK 3.97 fin red, 3rd gear 1.72, force at contact patch (425Nm peak torque) = 4,200 (using GT3 final reduction and third - 25% improvement over the manual)
991GT3 PDK 3.97 fin red, 3rd gear 1.72, force at contact patch (460Nm peak torque) = 4,546 (GT3 8% improvement over the above)

I'm not really expecting any insights - there are none to deliver.
However, with low torque cars you have to use torque multipliers and a slippery quick transmission to get the job done. The whole engine 3.8 or 4 is, in a way, a magicians trick, look over here its bright and shiny whilst all the more material action may well be elsewhere.

The gearbox from the 981 to 718 GT4 CS remains the same with the exception of the ramp angels on the differential. ZF revised the ramp angels to better suit the car

Thank you - well that certainly constrains a few things

Crossing my fingers we get the PDK option with these improvements on the next GT4

Let's hope the street car has the above added cooling. It would be nice to have a PDK Cayman and not have to replace the transmission. Did they finally address this weak point?

Is the PDK known to be a weak point on the 981 and 718? This is the first I'm hearing of this (currently have a PDK 718 S).

So that amount is lost when you sell the car. So it's not an option to get another performance car every single year!
Same thing in the US, we pay sales tax on new and used cars. Depending on state it can add up to about the same amount you paid. In California it is about 8%, give or take a point, so I just forked out $7k for a lightly used GT4 recently. It sucks and is one of the reasons it pays to keep an expensive car a little longer.
The only way around it is leasing, as you only pay taxes "as you go". Meaning on the lease amount, but then leasing has other fees and isn't worth it for most individuals.

Markets are discounting machines. They take into consideration all available information and present and potential future events.
In other words, people have been "unloading" their GT4's in anticipation of the new 781 for quite some time now.
I feel the same way. The market took the new 718 GT4 in to account already, which is why prices dropped a bit last year, AND why there are a lot more of them for sale.

The truth is if you bought a GT4 new or almost new at about MSRP and drove it for 18 months you would be able to recoup most of your purchase price. By waiting 24 months (spoiler: I waited too long) I lost a little bit. By waiting until the new one is announced I predict I'd lose a lot more. So why not time it to keep more of my money in my pocket? That's just called paying attention.

Drawing a parallel between cars and the stock market is silly, car's shouldn't be viewed as investments and with few exceptions they aren't traded as commodities. The best one could do is time it right to minimize their losses.
I don't think he was suggesting that cars are investments, just that the markets look ahead.

Yes, you lost money by holding on to it for another 6 months, but that was most likely the biggest dip. Once the announcement for the 718 GT4 was made, many (mainly the speculator types not the enthusiasts) started selling, thus changing the supply and demand. And new potential buyers were not as eager to buy because of the prospect of the new one. However, reality is starting to set it, or will soon, which is, to get in to a 718 GT4 one will have to pony up $120k +, if you can get one. So with that in mind, $85-95k seems like a great value for a barley used 981 GT4. IMO, until the 718 GT4 market gets soft and saturated, which will take 2-3 years, the 981 GT4 market will not suffer further. The $15-25k price gap is already established now.

I agree with this. I think the 981 GT4 market is soft right now as there are a number of buyers sitting on the sidelines waiting. It's a bit of pent up demand if you will. Once they realize it's going to cost them an incremental $25k+ to get a 718 GT4, they will look to slightly used 981 GT4's.

Just my opinion of course.

Yes, that is what I was trying to say.
Markets are discounting mechanisms that look AHEAD.
Moreover, I believe that your assessment of where the current 718/981 market place is .... is spot on.

The 781 is simply a a typical progressive model update by Porsche to an already great 981. No radical advancement.
Meanwhile, the economy has softened up quite a bit. It will be interesting to see what kind of ADM's appear from the dealers.
