Same issue.

How’d you find the performance of the 718 GT4?
Superior German engineering! I think the unusual heat of lapping on track combined with harder than usual shifts somehow exposes a flaw there.

GT4 did well actually. It's got legs, even bone stock. At the end of Sochi's really long straight it was going as fast as my 450 HP PDK race car which comes off the previous corner a lot better with the slicks. That car does have a draggier wing on it, but still. Overrated the 4.0 is not. And it's just got such a wide powerband compared to the previous gen. Maybe the peak torque isn't any higher (officially) but you get away with picking a longer gear through some corners just fine because it's just there throughout the entire rev range from 4K onwards. Suspension a bit on the soft side and the rear is too unstable on initial turn-in but that's with our "just slap some more camber on and we'll see what it does" initial setup. The Cup 2 tires are still the factory set and have 6K street miles on them, not ideal. Brake balance and ABS are much better than on my 981 race conversion, but the TC needs to be off to get out of corners at full tilt. I experimented a bit but mostly didn't turn off the nannies because of the loose rear and the speeds involved.

Not the best lap but I ran out of GoPro batt.

Nice. I gave up my M2CS allocation last summer to get my GT4. My BMW called me when their car came in last month and offered it to me anyway, but it just didn’t make sense to have both. I would absolutely love to have one though . . . My F80 has the M3 CS suspension on it and it really transformed the car.

Is this something that can be checked and fixed before it happens?

Default does the PDK fix the GT4's long gearing issue? (GT4RS)


unfortunately, the answer is no. thanks Matt Farah. I was hoping this would be the advantage gained from the GT4RS's PDK, to have a more active gearbox, but reduction in gear length is so minimal that it doesn't make a difference. while driving hard on his usual road.. barely got into 3rd gear.. most of the time in second even with pdk. As a previous Spyder owner who hated the long gearbox, this is disappointing. damn

2nd gear manual: 83 mph
3rd gear manual: 113mph


2nd gear pdk: 79mph
3rd gear pdk: 108mph

Matt takes a Cayman GT4 on a public narrow mountain road and complains about long gear ratios. Give me a break!

That top of 2nd PDK number is wrong. I’ve banged it against the limiter in manual and in auto dozens of times; the number is 73 mph.

I doubt the top of 3rd is correct above either. The PDK gearbox is around 10% shorter so you can do the maths.

Farah has the standard YouTube "journalist" qualifications - none. I pretty much watch YouTube reviews for laughs.

I believe these are the correct gear ratios. I used the front tire size. Let me know if someone has other data.

PDK is first (obviously).

He's driving it, he notices things, like us. just as valid, plus extensive experience. why the hubris?

Don’t know why these calculators keep spitting out wrong numbers but real world PDK 1st/2nd is 43/73.

3000 miles on my Spyder and every drive hitting those numbs.

None? The guy’s driven pretty much every modern sports car on the planet and probably has 10x the seat time of most of the keyboard jockeys on RL. You know he wrote for Road & Track, right?

In my Spyder with Michelin Cup 2 tires these numbers are dead on. TX shaggy what tires do you have?
