Hi,
does somebody know the oem spring rates of the various Cayman 718 versions?
I have a 718 with Pasm and I feel the rear to soft , I would like to compare the values with the pasm sport and the GTS in order to understand how to modify mine...
Thanks

I thought the GTS came with the same choice of suspensions as the S: PASM as standard and SPASM as an option. Does the GTS come with a different choice of suspensions than the S?

It's a good question, and I'm a Porsche SA, so in theory I should have an answer... As far as I know, the GTS has the same suspension that's in the S car with PASM. PASM comes standard on on a GTS, but it's a $290 option for Sport Springs (S-PASM). I couldn't tell you what the spring rates are. The GTS naturally looks lower than an S car because of the front and rear fascia.

So what is really changing between the cars it’s just the anti-roll bars?
The same Pasm that I have on the 718 2.0 it’s the Pasm that is standard on the GTS?

Thanks! Yes it seems to be a difficult question. I ordered the CGTS with Sport PASM (-20mm). The dealer couldn't tell me if there is a difference with the Sport PASM of the S. Most journalists present the GTS as being -10mm lower than the S. But the S with the same suspension (PASM) is -10mm. Some other pretend that the sway bars are bigger. Other say that sway bars are the same sise but stiffer. Some say that the spring rates are different on the GTS on both suspensions... etc...


Does any one know?

Hey guys, I'm sorry to resurrect another old thread...but did anyone ever find out what the spring rates were for the different Cayman trim levels?

You can get a pretty close estimation of spring rates by doing math (yikes!)...or using a website with a spring rate calculator. I've used this one to ballpark it in the past, and it works pretty well: Suspension Spring Rate Calculator

That said, I'm asking because I'd like to understand the differences of TechArt lowering springs, for example, compared to stock. Knowing this will help me decide if a coilover upgrade is a better direction than stock struts with higher-rate springs. One is a lot more cost effective than the other.

GTS comes with PASM standard. Sport PASM is optional.
S comes with non-PASM. PASM optional and Sport PASM another option.

I think the only difference between sport and normal PASM is that Sport has shorter, stiffer springs. Don't know the rates of either setup.

I didn't notice that the GTS has bigger sway bars than the S. Since they no longer make the 4 cyl GTS, it's harder to look up the diameter. I could measure mine, I guess. (Don't hold your breath waiting, however. Next time it's on the lift, if I remember...sigh.)

Matteo: Yes, that's my understanding. My standard PASM Cayman GTS is very docile and comfy. It's less of a go-kart than my '06 was with coil-overs, bigger bars etc, but I like the balance for what I use the car for most...driving around and occasional anti-social but safe behavior.
