Numbers in parens are final drive x gear ratio. The PDK gears are about 10% shorter

All technical specs are posted on Porsche's website.
Not doubting you, but can you provide a link to either the GT4 or Spyder that shows the above? I’ve looked all over the Porsche USA site for both cars and haven’t found anything showing the PDK gearing.

Go to Porsche Newroom, then find the link to Porsche.de Newsroom and request English language. Look for releases by model. Full spec sheets are there.

I found it!

The instructions are correct, but I used the Pressroom as the starting point, then followed TXshaggy's instructions:

1. https://press.porsche.com/prod/press...0?OpenDocument

- Click on the Flag and choose "Germany" for Country/region, then "English" as the language

2. Select 718 GT4 under "Products" tab
3. Download Technical Data PDF

Attached are the PDFs for Manual and PDK where you can see the differences in gear ratios.

These are the speeds in gear for comparing the PDK to the 6-speed from a transmission calculator.

long gearing tall gearing, lots of people complaining... after 6 months ownership, I found gearing is not an issue at both maintain and city spirit driving.

on paper, PDK has slightly more tourqe, shorter 2nd/3rd, faster upshift, but slower 100~200km/h than MT with two upshift. transmission efficiency? extra weight? what missed?

Dude, happy that you think your manual is just fine. This is not a comparison thread; but rather one discussing the PDK.

BTW, all gears 1-6 are effectively shorter.

I have a much-modified 981 GT4 with the shorter 3,4,5,and 6th gearset from Holinger fitted. The car is used mainly on the track and is definitely more fun and involving as more gear changing is invloved. Probably no faster than OEM due to the extra gear changes. I have ordered a new 718 GT4 with PDK for road use as I'll keep the 2016 car for track stuff. Selling my 991.2 GT3 which is great car but I've not gelled with it; I love the GT4 exprience with its smaller coseting cabin.

Yeah...right! I can see you switching between the two at the track...I have read the mods on your 981, would be interesting your opinion of how it will compare to the 718 PDK.

Has anyone seen any real life pictures of the PDK shift paddles or the shifter on the GT4?
