And if you believe in the idea that for any particular car, for every spring rate, there is a corresponding matching dampening rate, then Bilstein's PASM approach (small range of dampening rates) makes a lot more sense. In other words, the 2 dampening rates of stock PASM are so far apart from each other, that perhaps one must be wrong (out of range)? This is a big factor in my decision to go with the Bilstein coilover, and not just a spring change; I was suspicious of the stock dampener and didn't want to re-use it.
I continue to be skeptical of that Firm setting of PASM, across other 997's like C2S and GT2 as well, not just the Turbo. I keep thinking next gen's PASM will be different from the current implementation. Maybe a third setting in between the two current levels, or a softening of the jittery and hard Firm setting?

Can, I would agree with your statement regarding the differences between normal/sport.
I recently replaced my Techart springs for the PSS10's and it was interesting to note how different the two setups are with regards to the sport/normal button.
there is much more difference between normal/sport with the springs. As Can said, the difference with the PSS10's is almost indistinguisable - although I only have a few days on my car, so i'm sure I'll learn to feel the nuances between both settings.

That music to my ears regarding NVD! Thanks for feedback!
After toe links, dog bones and bushings next in the list are GT2 seats (-20kgs) and titanium exhaust (-20kgs). Together with the dymags and the pccb the car should start feeling a lot lighter.. (It already feels 100kg lighter compared to my friends 997tt with stock wheels and big reds).
A friend is watching as we speak the supercup race from the paddock at monza and the mechanics there told him that changing to lightweight doors makes a HUGE difference (-50kgs) and it is possible to swap them back and forth for track days.. Damnit the story never ends with those cars!! Lol

I thought TOE-LINKS were to improve stability that GT was talking about?!.
I also thought the advantage of the GMG sways is that you didn't need replacement drop links as the sways are engineered specifically to fit the Turbo so you don't have to worry about getting custom longer drop-links?!
The advantage of stock verses Tarett (and and other monoball style end links) is that the monoballs will eventually cause them to make noise. That's why GMG recommend staying with the stock style drop link. I have been told by other sources that the Tarett links are pretty, allow finer adjustment but are not necessary. And they will wear very quickly without protection.
I am looking forward to my toe-links and dog-bones kits when they arrive though. Ordered but have no idea yet when they will arrive from the States.
(see enclosed picture). THAT said, your plan is excellent as is and IMHO because you are adding a few components already, I agree w/ you that the Tarett could wait.
. Initially my car was installed with the stock drop link. However, once I saw it in person, I went ahead with the change. Tarett was an easy choice because of their remarkable reputation. Most importantly, those who use the Tarett drop link don't revert back to stock, not one that I've seen. No long term noise complaint either.
. When I changed the sway to full stiff rear, it was intolerable. I am now in the middle setting and am debating whether to make it even softer.

Just changed rear sway setting for 2 to 1 and indeed the balance of the car changed substantially from power oversteer to more neutral. However the one thing to report here to all who are using adjustable sways is that the difference in ride quality for city driving is quite noticeable when loosening those sways. Contrary to the theory (that sways don't affect lateral suspension movement but only while cornering) stiffening those bars makes a big difference under almost all conditions. So since its only a 15min thing its worth reverting to softest positions when in city/ winter etc only to drop-by your mechanic to switch when a track day is coming up.

Switching to drop links doesn't require 'tearing into the suspension', it's a 1hr DIY job.
Again, not required with GMG sways(others ?), but they look nice I guess.

I wonder why 911 Carrera Cup racing cars have stayed with production drop links when there are nicer looking ones available.
Chris (TTSurgeon) and you are making me work hard. To answer your question: Why do people stay with stock link in cup cars?
. This situation may or may not happen in the cup car.

First, because the setup in the cup car is not the same as the Turbo. With after market sway AND lowering, the angle between the sway bar connecting point and the suspension frame has changed from stock in the Turbo. This causes a change in angle of connection (see picture above) that as mentioned may be acceptable, but not good enough for me

I believe Porsche Parts can supply any length stock drop-links. My fitter says he can get me any size very easily without having to go to Tarett.

When installing the Bilstein coil overs, I would recommend installing the Tarett drop links at the same time. They don't add that much to the overall price of the mod and it would save money in the long run, because you wouldn't have to pay to tear into the suspension again. They are definitely better than the stock links or the ones that come with the PSS 10 kit.
Can, I'm surprised you've managed to keep this thread going for so long. It must be some sort of record.

Little track update, went to Watkin's Glen on Monday, first real chance to try out the new suspension on a long, fast track.
Even though it was alittle wet in the AM, it dried up. The car just flat stuck like glue! I was going faster than I ever have there in the past, 2:10 in the red group. The car handled great, no body lean at all, no pogo effect, basically ate everything whole in my group. I wouldn't touch a thing on this car now.
Here's a shot in the rain.
