Lots of variables at play there of course but the weird thing is that the GTS has the SPASM as standard, if you adjust the S the same amount then by the book it actually sits .2" lower than a GTS. What to make of that I don't know!
Interesting observation about the overall heights of the different variants. Comparing the base Carrera, Carrera-S and turbo between them, the height variances seem directly correlated to the variance in tire sizes (rolling diameter). The oddball is the GTS that is quoted to be the same height as the turbo despite having the the lowered S-PASM standard with the same tires as the CS. I seriously doubt they made the GTS ride higher than the CS.

It doesn’t change anything about the function of helper springs though…

Unless you put it side-by-side next to a SPASM equipped model, you don't notice it.
Here is my wheel gap on PASM. Hope to rectify that "problem" very soon. Just too much for my personal taste. SPASM is a little better but I would likely still want it a little lower.

That does look pretty high, but I'm a little OCD about ride height. That angle is always going to be brutal when it comes to wheel gap.

With all the black accents, lowering your car will look really good.

that’s true, helper springs do ‘help’. My issue has always been that people take what Porsche said about those and make out that somehow the GTS now has ‘Turbo’ suspension, as if that’s really any different to say a base C2. Great marketing by Porsche, that’s all.

If it makes you happy to think that the suspension on the Carrera S is that same as the S-PASM on the turbo and GTS, I will not stand in your way

its all relative, i traded a 992S SPASM for a GT3. . i liked it and thought it was stiff not unbearable but plenty firm . compared to the GT3 the 992 spasm is like a Buick. carl

I would say it depends where you live and how do you use your car. I am happy I have standard PASM because of comfort for daily drive.

My friend once said: ,,That front axle lift is a great feature, isn’t it?”🤣 … but I don’t have front axle lift🤣

On pictures or direct compare to SPASM it doesn’t look nice, but in all other situations I really don’t care about that gap. I am not tracking the car, but I never felt standard PASM too soft. It is 911 and in sport suspension mode sometimes stiff too much even with only standard PASM.

I got the PASM 10mm raised on GTS. Car is going to daily drive in Los Angeles. what are you thoughts on both ride and look impact?

If you encounter mostly good roads, SPASM is a plus with slightly tighter handling (and of course that 10mm lowered look). The GTS offers higher spring rates and Turbo helper springs, all to take the McPherson strut car closer to its theoretical handling limit (Add Sport Cup tires?). Lightweight options can improve upon handling even more. All this comes at a price of ride quality and if you drive abominable roads as I do, it detracts from the experience. The GTS Targa only offers the raised suspension (essentially the standard CS suspension). For a daily driver, that makes perfect sense. I doubt you can notice the improved SPASM handing in normal driving ... to do so would require speeds far in excess of legal limits in the US, and given typical road quality and lack of run-off would be risky. Of course, if you're a track junkie, go for it. From base to Turbo S and GT3 RS, the 911 offers limitless options.
