Yes...I have that setup from my 981 and will use it again on the 718. The only thing that would be very close is the end of the rear toe link...you will have about 5 mm clearance.

Awesome to see the 718 gt4 with pdk coming in first!

Thanks for sharing.

For reference in an August test by Sport Auto at Hockenheim a C8Z51 did a 1:54.6, a R8 RWD did a 1:54.2, a 992 Carrera S did a 1:53.5


From the locked thread:

The 718GT4 seems very loose, having problems putting the power down.

Compare that with the Sport Auto video that I had posted previously of the C8, R8, 992 Carrera S.

From all the cars been tested the 992 C2S seems to be the most composed,and that was with a car not wearing R-comps like the GT4.

The testing was done on different days, but neither the M2CS nor the Lotus that was tested on the same day seemed to be loose. (in other words doesn't look like track conditions)

A comment on PDK testing in the press - the automotive press are "too cool" to let the computer shift the PDK. I've never seen a racer or magazine test a PDK car without shifting it manually. The car is simply faster, better, and more stable (in most scenarios) if the computer shifts. Press drivers have a manual bias so they shift it like a manual transmission. There are a few things in specific that the auto PDK computer does better: It will downshift to red line at each gear change after a long straight resulting in improved braking performance; it will quick shift mid corner putting the car in optimal torque band even if only for a millisecond. And, generally, a driver will do all the other tasks of driving fast more precisely when he has more mental band width available by allowing the computer to doing most of the shifting.

FYI: The PDK on the 992 is coupled with an e-diff vs a traditional mechanical diff on the 718 GT4 PDK. An e-diff makes a huge difference on how well/efficiently a car puts the power down.

For the 718 GT4 and Spyder the lockukp/overrun values on the LSD of the PDK version of the car also differs from the manual transmission version of the car.

So I don't expect the handling under trail braking or under power while cornering to be exactly the same between the MT and the PDK version of the cars.

I wholeheartedly agree with matttheboatman's above remarks, and that GT4 was not set up right and he probably lost at least a second from that on that lap. On the one infield corner, he slowed way down and was off power when the car had a sizable drift.

But the GT4 also has torque vectoring.

Having said that, e-diffs are awesome. I have one on my SS 1LE and it really does wonders on tight corners. It's constantly locking and unlocking based on what the car is doing and what you are asking it to do.

The e-diff is one the biggest reasons why the 991.X series of GT cars are so fast, it allows the driver to get on the power so much earlier compared to a car with a traditional mechanical diff.

The 992S is as fast as a 991GT3, due to the addition of the e-diff. The laptime difference between a 991.2S with PDK/LSD(PTV)/RAS vs a 992S with PDK/e-diff/RAS is substantial.

what are the failure rates of pdk on track? its the factor i seldom hear about. Given that the clubsport cars have pdk as well, is reliability on track a concern?
is 20k the cost of replacement or exchange? That's not too bad really
