GTS question
#16
I read and heard (on reviews) that GTS suspension is different from a Carrera S, this would have to be the case on the RWD cars due to the wider track. Most reviewers did say not to get S-PASM as it ruins the "perfectly" tuned GTS suspension. The general quote is:
"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."

Certainly suggests that there are some tweaks.
SharkWerks claims all GTS cars came standard with SPASM. At least, that's what SharkWerks claims here:

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.

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.

I seem to remember reading in excellence that the GTS vs. 997.2S suspension is not the same. It could be that the difference lies in the sport suspension equipped cars.
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.

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.
