Looking at 2 different 991 gts. One has psam listed as an option, and the other does not. I thought it was standard on a GTS?

Thanks

I thought PSAM was standard on 991.1 GTS, and Sport PASM was optional. But, I could be wrong.

If there are pictures of the interior console, you should see the "Shock" button for cars with PSAM. I am not sure if there is any additional indicator for cars with Sport PASM.

Edited post, I was wrong

My GTS came with this as one of the many options as listed on the factory options list:

031 Porsche Dynamic Chassis Control (PDCC) combined with PASM sports chassis (- 20 mm).

GTS came with PASM standard. SPASM was the option.

Are you sure of that? I know the carrera S comes with PASM standard, SPASM optional. I though GTS all came with SPASM standard.

Positive.

Here is a a link to the original sales brochure that explains it. https://www.stuttcars.com/wp-content...11GTS_2015.pdf
I have SPASM and it's just low enough - some days a little too low!

FWIW, I can't find the words Sport PASM in the brochure. I would also note that it appears to be from the UK (colour) whether that matters or not.

I found this passage that does suggest that PASM is standard and something beyond that is optional. Running my VIN on Vinanalytics does not show any suspension related options so I am assuming my GTS only has PASM without the additional 10mm drop.

Going by the unfortunate condition of my front spoiler lip, I don't know that it would have survived being another 10mm closer to the ground.

I guess it depends what market you are in because 031 in my market states "Porsche Dynamic Chassis Control (PDCC) combined with PASM sports chassis (- 20 mm)".

I have no idea what the 352 stands for in the chart above showing 031/352.

Here's an Oct., 2014 press release announcing the 991 GTS models. It seems that PASM was standard. It lowered the car 10 mm compared to a base model Carrera. The optional PASM Sport suspension had uprated springs and lowered the car an additional 10 mm to 20 mm.

Exactly and according to the Porsche info I have, the spring rates are as follows:

Front Axle
Basic Carerra: 24 N/mm
Carrera/Carrera S PASM: 28 N/mm
Carrera/Carrera S PASM Sport: 33 N/mm

Rear Axle
Basic Carrera: 48 N/mm
Carrera/Carrera S PASM: 62 N/mm
Carrera/Carrera S PASM Sport: 108 N/mm

99-911

Good to know..
I thought Passive Sport Suspension X73 was a no cost option on the GTS.
I know that was the case for the 981 GTS platform, I thought it applied for 991.1 too.

I stand corrected:
991.1 S & GTS models have either PASM or SPASM, no passive (sport) suspension option.

PASM was standard. SPASM or PASM Sport Suspension was included with PDCC or as a standalone option. The build sheet for my car.
