adias....we're based in Florida and I'm not familiar with this race team. More interestingly, I'd love to know how they simply "open the tranny and close the tranny", as the Porsche PDK is a non-serviceable unit. This means that is literally has to be CUT open in order to inspect the clutch packs. You can not open it like a GTR tranny or even the Audi/VW DSG. I wasn't aware that there was anyone else out there who has done this besides us, let alone right in our back yard.

Please see Post #24 above. Better yet, as you are in FL, contact Speed Merchants directly.
Knowing what I know about the PDK, I question some of the terminology being used (with all due respect to mdrums, whom I know very well).
PDK clutches don't wear....it's not that type of system. And a PDK can not be opened to inspect the clutches...it's simply not designed that way. Anyway...I guess it doesn't matter, I was just curious.

So what maintenance does PDK require? If the clutches don't need to be replaced, I can see that as being another advantage it has over a traditional manual. But are there other normal wear items that need to be replaced within the transmission? Do they have a shelf-life? Or is all that unknown still because it's so new.

2012 Porsche 911 GT3 R has paddle shifters...but a traditional clutch.
Just read about it and figured i'd mention it here. Not a PDK...but closer.

Most race-cars have a similar setup. Our R8 and R10 had a clutch pedal too, to assist with first gear starts. Once you're moving, no clutch pedal was used.

Not in a 911 though correct? This is a first for a Porsche 911 factory race car.
I believe so....pretty cool. All the past race cars were sequential boxes, which do require the clutch.

I watched a recent episode of Top Gear that showcased the Lexus LF-R. They said Lexus chose a single clutch paddle system because people (and Lexus engineers) didn't like the ultrafast/smooth double clutch action of PDK. They said it was numb and I tend to agree. The single clutch at least presents the driver with the physics of an actual shift.

I think you'll find that many people on these forums hide behind their computers and if given the chance to say the same thing to you in person it would be more subtle and more carefully worded. The forums are nice for getting information but not so nice to find friends. This is my Opinion.
I found your comments interesting and didn't take it any other way but your opinion.

I saw that Top Gear LFA episode with lots of interest since I went to an LFA event at Infineon last March.
A friend who has an LFA on order was at the Nurburgring last week when it did a 7:14 lap. He said it broke the record in automatic mode. As someone who has never owned an automatic (or clutchless manual), maybe it's time I give them a try.

I like that my head doesn't fall forward during a shift, but rather get hit in the back 4 times on the 1/4 mile (launch, 2nd, 3rd, shifting into 4th at 120mph). It is, indeed, a unique feeling.
