Just an FYI regrading shifters, the 997.1 GT3/RS did not have a GT3 specific shifter.
It was the same shifter used in all the 997.1 /987.1 series.

Ditto for the 997-on GT2 clutch. I always get used to it within a day or so, but it seems better suited to a GT3 Cup (yum!) than a GT3 street car. But that's just me.

Whether it's the shifter, the linkage, or on the transmission end, it is too stiff in my personal view when compared to other Porsches, even the faster ones such as 987 Boxster Spyder/Cayman R, and Turbo. And 996 GT3, for that matter...

ps. All car reviews should include a cabin dB meter reading continuously for 0 to 60 or 0 to 100 tests. The 3.8 RS is maddeningly noisy in the cabin.

The Box/man cars are quite different so I 'll leave them out.
The 7.1 GT3 and the 6 GT3 use the same cables.
The gearboxes are quite similar.
The 6GT3s shifter is a long throw one when you compare it to the std 7.1 shifter (the same was used in the 6 series.)
The extended travel gives this sweetness to the changes as it takes away the knochiness of the shorter ones.
In fact the 6 cup shifter has the same travel as the original 6 shifter but it's more robust with added metal on the ends.
Perhaps the added time for each change, that allowed the gears to engage more smoothly, was what made Porsche use it vs. using one of the shorter / later ones.
However most 7 users don't want to go back to the longer throw shifters. The 997.1 shifter has a side metal plate reinforcement vs the 996 series shifter.
The 7.2 GT3 shifter is as short as the 7.1 one but with added metal strengthening plates and bushes. Also the cables in the 10 cars are different.
More robust for sure but feels the same to me as the 7.1 did.
In any case and while the shifter thing is a personal preference, all GT owner that track their cars should buy and install the 996 cup cables.
Great mod with added noise being the only negative.

Hmm. Interesting... never had a problem here.
Ah, what "should" be. I should buy a set of scales, and should get some real measurement devices. db meter is a great (!) idea, but I'd have to figure out a stretch of representative test pavement. And that, of course, is always degrading until it is radically improved.
Now, how to buy that equipment and add those tests within my budget — and, more importantly, time —*is, well, hmm... something to think about. Not saying it can't be done, but have to count the costs and opportunity costs. I look at those supertests with flat-out awe. Independent windtunnel testing!? Now that's A-game. So far, I've been trying to focus on the stuff the big boys don't do well, which is nuance and detail. Of course, it helps being marque-specific.
Oh yeah: 997 GT2 was the first 911 where I thought I wanted more sound deadening. Not for the engine, but for the rear tires. On bad freeway pavement, it was unreal how loud it was in the cabin. On nice pavement, no problem.

I have cup shifter and cables. The setup is smooth as butter, yet precise as a scalpel. Wouldn't wan it any other way.
Can't comment on the noise since I've had it from day one, but whatever the drawback, it's worth it.

shifter feel?
honda s2000. everything else sucks.
if you must drive porsche, 996gt3 stock shifter in my opinion is much better than 7.1 7.2 rs or not.
and if you really like to shift, swap cup shifter AND cup cable AND have it adjusted correctly. then it would be almost 1/2 as good as s2000. but better than the rest of the porsche GT3 variants.

but the s2000 shifter is a lot better than 993 shifter.

If you don't have at least half-way adequate safety gear (DAS roll bar and HANS) then I'd discourage too much track driving until you addressed the safety aspects of near 500hp, 3000lb and rear engine ...[quote]
Alex looked at my LSD when he pulled the tranny. He said it looked 'fine'. I will ask him about it again manana. Snowboarder has 'zero LSD' remaining in his car, according to sharky.
This whole SW process started with me asking about a Brembo brake upgrade. Based on what I told him about my driving habits (2 track days in 1.5 years), he talked me out of it. His reverse psychology worked well. I then bought the 3.9. Now I need more track time.....and brakes. I will ask. I do not want to die.

I'll leave it to Sir Excellence (kidding) to address the PASM versus real suspension question. I'd be interested to know what else you've got in order to fully build this car. If you don't have a Guard LSD in the build, then you should reconsider. Same for brakes -- not mandatory, the stock brakes work reasonably well for moderate track pace. At the least, I'd get the ducts for rear cooling. Brembo or PFC or whatever would be a great upgrade. Maybe a step of Stoptech GTR if the budget allows. But something for brakes would be a worthwhile consideration.

I just sent a big check to Sharkwerks for the 3.9L upgrade to my 997.1 GT3. I'll have 3.9L car #14 I'm told. Does anyone here have one? Comments? Alex has been great to work with, and everything I've read of the rebuild is very positive.....but I'm nervous. My 3rd child is going under the knife.

I have one. It's okish
It's neat to see you on RL. You're going to meet some very strange gt3 people here. All they do is cost me time and money. But I've met some amazing people as a result. There's pluses and chocolate Easter eggs so stay on -board!
I can't believe you managed to break the 3000mile mark on ONE set of tires. The Pilot Super Sports are amazing:P Either that or Tony needs to give you an even more aggressive alignment
My wife was not exactly thrilled when I came home with it. She laughed (not kindly either) and said, "You waited 18months and specced it out like this? You said it was green. That color is asanine (**** in my lingo)".
Don't you start! Dan and his S2K is going to join this thread. He would rub that in our noses every day he owned that car. Honda did nail it. Trans is right there too. No bs cables etc.. A stick and trans right underneath you to shift. And if somebody even brings up the NSX I'll...
PS Anyone seen the footage of Senna at Suzuka helping with the NSX?
Um... distributor
Well, lest my sense of humor be misinterpreted, I'll start off by saying, no sarcasm, full points to Alex and the Sharkwerks guys for listening to the driver. If you're currently at a couple of days on the track from year to year, maybe you'll never see the light (sorry, there's my idea of wit creeping in) but maybe you'll "grow some" (again, sorry) and then you'll plug in the LSD. But I can't make that decision for you and certainly, nor can the company selling the track gear.
I have to say it's a real pity that Porsche went backwards on the LSD unit. The one in the 996 far outlasts the 997.1;( The 997.2 isn't much better either grr. The pressure plate too is a bit poo-ey for that matter.
Be safe at the track and I want to measure the thickness of your mega rotor at least three times this year

The shift feel and function in the 997.1 GT3 and 997.2 GT3 RS are both pretty ordinary, bordering on annoying. Getting a downshift into 2nd gear under brakes is not a given. I don't want the cabin noise transmitted by the heavier cables, just the assurance that 2nd gear will always be in the same place regardless of engine load.
