"The wider track (by 2mm at the front and 32mm at the rear) has allowed some suspension reprofiling, so you get stiffer springs and anti-roll bars. The 19in rear tyres are wider too, at 305/30. Porsche claims the GTS is “more neutral” than the Carrera S."
That quote is from this article in Autocar:

http://www.autocar.co.uk/car-review/...11-carrera-gts

Certainly suggests that there are some tweaks.

SharkWerks claims all GTS cars came standard with SPASM. At least, that's what SharkWerks claims here:

http://sharkwerks.com/porsche/porsch...09-2012-a.html

Not certain that's true, I certainly don't see any references to in the Porsche literature. There was option "030 - PASM sports chassis - 20mm", which I believe drops the suspension an additional 10mm over the standard GTS suspension (which itself is a 10mm drop from the base cars without PASM). Note that option 030 was also included as part of option package P17 (which also includes option 220 - LSD).

I strongly suspect that when articles refer to preferring the standard GTS suspension, they mean as opposed to on GTS cars equipped with Option 030 or P17. But I have no first hand basis for comparison.

For all I know, this may all only apply to the 2WD GTS Coupe. I have no idea about cabs or the 4 GTS.

Maybe the C4S is the same as the GTS 4.
But the regular GTS has a much wider track than a C2S, so they likely used those torsion bars to adjust the handling character, match that with the wider wheels, I'd be surprised if Porsche didn't do some tuning.

I am sure S-PASM had a smaller take rate than the entire GTS model range and that has been tuned to each 911 variant.

"The Porsche Active Suspension Management is standard, though on the softest setting, the ride is still fatiguing. Yes, even fitted with the PDK transmission, the GTS bludgeons you with the full 911 experience." http://http://www.caranddriver.com/r...ad-test-review

Basically what Car and Driver said. It is what it is. It's a GTS and I agree.

Sharkwerks is clearly wrong with their assertion that all GTS cars come with SPASM. As you have pointed out, it is an option on the GTS and I know because I paid for it on mine. I am also just about positive that SPASM is not even available on the GTS cab. Just another reason to not believe everything you read in automobile magazines or from aftermarket suppliers.

You're absolutely correct. We wrote the guide a long time and however with a few of us writing it (I think I did that part with most of the GTS' we were getting being on SPASM) together mistakes can/do happen. It was just a free passionate thing we chose to do to help people if possible since we owned the first 997.2S delivered in California for a couple of years. We're only sharks.. or human I suppose but thanks for the heads up and we can easily fix that error.

My GTS does not have SPASM. It was definitely an option on GTS coupes. I understand that cabs were offered with PASM only -- no SPASM option.

Here is the complete options list for 2011 Carrera GTS according to Motor Trend: http://www.motortrend.com/cars/2011/...kages_options/

P17 is an awesome option.

Edmunds did a two part review of the 2011 GTS. A fun read that makes me want to keep the car forever.

When I traded my 997.2S with PASM for my 11 GTS, also with PASM, it seemed that the GTS felt a bit tighter. Or maybe I wanted it to feel that way as my wallet had been lightened a good bit.
I read that same article.

I don't know, maybe the parts are the same but they are put together differently. The Excellence article referenced above clearly stated that the GTS was "tweaked" and most definitely not the same, performance wise, compared to the S. In fact both the author of the article and the lead Porsche engineer (?) for the GTS stated that the suspension or maybe it was handling was different (I'm just reiterating here). Further both agreed that adding SPASM, which was a carryover from the S options and not specifically for the GTS actually changed the handling characteristics (in their opinion not for the better). So, according to those sources, there is a difference in handling. Whether it is related to the actual parts in the suspension or how those parts interact with some other aspect of the car, I have no idea.

Edit: A little digging. According to Excellence the GTS has a 3 mm thicker, hollow front anti-roll bar compared to the Carrera S; the Porsche "Engineer" I mentioned was actually the director of the Carrera product line, August Achleitner, and the basis for GTS handling differently may be the dynamics of the wider track/offsets.

The TPMS on the newer 911 models (at least 2009 up) takes the tire temperature into account (as well as your driver-entered weight loading) when giving the plus-or-minus style tire pressure reading it provides (the one available only when the car is still). If this one says the tires are low, then they are low regardless of the outside temperature.
