All for PDK being an option!! Just not the only option!!... Plain and simple...
For me personally, the motivation for going to the track is to better my skills and work on closing the gap to my pro driving instructor's time... The day I'm within a whisker of his times is the day I stop tracking... There is no prize that warrants going back week after week and reeling off perfect laptimes for me. PDK will just close that gap despite a lack of talent as the art goes out the door and it comes down to taking the same lines and braking at the same points whilst car does the rest...

Re: Cup car centerlocks - due to some arcane DOT rules, the Cup Car system is not road legal <sigh>.

Correct Bob, they are not street legal as the secondary locking system, that is, the red pins can't be secured effectively to make them tamperproof...

If you are in the power band you can floor PDK and it will not downshift because it can't as it would be past redline. But if you floor it at say below 4k rpm's...floor it and hit the kick down button with the throttle pedal then yeah it will downshift very quickly and put you in the proper part of the power band. I'm not understanding why you would think this is bad?
I've found that if I keep the rpm's above 4k...maybe 4300...no problem PDK will stay in the gear I select. Why would you want to go full throttle at 2500 rpm Dave? Even at Sebring Turn 17 for example 4th gear at the bridge about 68ish mph I believe is around 4500-4800 or so if fine...go full throttle PDK will be cool.
In addition, the bigger picture: I want to select my gears, PERIOD. If I am a dope & want to floor it in 5th at 2,800 RPM, I should be able to do so. Supposedly a DRIVER'S car does not out think the DRIVER. if I want the car to pick it, I will just put it in D and go...which is fine.

I started this hobby late in life and chose a DCT for my e92 M3 because I thought I was too old to learn heel/toe etc. I tracked that car for 5 seasons and loved it. Perfect rev matched shifts every time. But I wanted the Porsche experience in this lifetime and no DCT/PKD option with the current RS. Considered a 991 for this reason, but in the end said what the hell and made the leap. I am now four (winter) months and three track events into the RS experience. I absolutely love this car, enjoy shifting, and it does give me a sense of satisfaction learning a new skill. But if PDK had been available in this car that is what I would have chosen. And knowing what I do now I would not have regretted it.

Im thinking the 991GT3 will share the same centerlock system as 991Cup.... One would like to think....
Worst case if it is still the 997 system it will be a nice mod to install the 991 Cup center locks and wheels...
As for PDK, if anybody thinks that it will be boring then they are just not driving fast enough![Smilie](https://rennlist.com/forums/images/smilies/smile.gif)

Cup car axles, uprights and bearings have a time out just like a street car centerlock

As much as I understand and agree that the CLs are not working out and YES! they are not necessary and YES! most likely they were just a publicity stunt on the part of Porsche,whose engineers have been watching too much F1 where they change wheels in 30 sec, BUT I also understand to be fair,that you can't expect a street legal car,made primarily for STREET DRIVING to not need a lot more maintenance when driven intensely and aggressively on the track!
The CLs will probably last thousands of miles without problems when the car is driven on the street.
Just think in Pro racing how much maintenance they have to do on Cup cars that involve a whole lot more than CLs: engine rebuilds and such...

I've probably asked this before, but am too old to remember...what is different, if anything, between the CGT CL and the 997 CL?
Also, I suspect that CL used on the street will last forever without replacing. We are talking about CL that are tracked.

The CGT CL is very close (but not exactly the same according to p/n) to the 997 RSR CL, and the flange from the hub that mates to the wheel is completely conical. The 997 Street CL is not.

Mike, this has not been my experience at Sebring. The PDK cars I have driven there (2 of them) have both done unwanted kickdowns at above 4,000 RPM's. So this is the basis for my comments.
In addition, the bigger picture: I want to select my gears, PERIOD. If I am a dope & want to floor it in 5th at 2,800 RPM, I should be able to do so. Supposedly a DRIVER'S car does not out think the DRIVER. if I want the car to pick it, I will just put it in D and go...which is fine.

In other words, you have hope.
