Wow sorry to hear this is the case, my GT3T already makes me a bit car sick…now I’m worried about the SRS..🤢

fxz

i have a 992 GT3 T...

Guys , for the SRS nothing to worry about, its a sexy lolita trying to kill you time to time but nothin too serious, CGT can do worse and imperfections on these limited cars is personality

just be aware when suddenly on a change of inclination ,

On track its another story , if i had a 4RS it was for sure at racing shop for a new set of suspension

Not sure I understand your last statement—are you suggesting that for proper track use, one needs to change the entire suspension set? Are your tracks particularly rough and bumpy? That sounds horrible if that’s the case.

I seem to do just fine with the stock suspension—on public roads and more importantly, on my local tracks—curbs and all. Of course with a proper alignment and some toe links for additional rear camber. I will say that this RS is my fourth Cayman, so maybe I’ve gotten used to its dynamic character and limitations, and have learned to work with it. It’s rewarding that way.

For those that primarily use their car on the street, and have to deal with bumpy, uneven pavement all the time, I understand that everyone’s comfort level with what feels safe and fast is highly personal. I’m all for modding the car to suit one’s tastes, especially as no car can be all things to all people.

But to claim that the GT4 RS needs an entirely different suspension setup to perform well on track is just false.

I do think that aftermarket suspension options, like MCS and KW can improve performance for both street and track. But unless your track is particularly horrible, surface-wise, I don’t find it an essential upgrade to put in fast lap times. I’d rather invest the $$$ in more track time, tires, brakes, and insurance.

@KelvinC Great comment. Little do they realize the 4RS is faster around the track then the 992 GT3. Not by my test but by Car and Driver.

Facts they simply want to ignore just to bash a Cayman because it isn't a 911 or they don't actually know how to drive a fast car fast.

Regarding the bolded, then you should consider the DSC controller...

Not sure what you are asking here, spring rates? The OEM springs are what they are, dialing in the damping would really help for the road.

This is an interesting discussion.

I am wondering if anyone expects similar behavior on the part of 718 Spyder RS, even with its more relaxed suspension setup.

Westcoast

Interesting enough to read post #14?

348SStb

Ha missed it. Thought the whole discussion was about GT4 RS.

Wondering if others expect or o have observed Spyder RS to tend towards this behavior or if it has been somewhat of a spurious account.

Westcoast

We would need more feedback from SRS owners to weigh in on this, my bet is the SRS would benefit from the DSC controller just like the 718 Spyder does.

I test drove three 718s Spyder and I thought the stability around sharp turns (on street roads) was very odd and unbecoming. Was this phenomenon in general at play there, causing me to conclude this, do you think? There have been posts here that 718 Spyder/GT4 also exhibit similar characteristics.

TXshaggy

This is not a new conversation, same characteristics on the non RS GT cars that’s been discussed here.

I assume slightly amplified on the RS cars.

FYI, the OEM suspension *are* (already a) coilover design.

there are a few variables you can play with:
- spring rates
- shock valving (to "match" the chosen spring rate)
- low speed compression
- high speed compression
- low speed rebound
- high speed rebound

both PASM and DSC dynamically adjust the compression and rebound.

with any (adjustable) suspension technology (DSC or not) the practitioner must be experienced in chosing the appropriate springs and damping, and then be able to
further tune that setup via the adjustment of the high/low compression & rebound ...

this is not plug and play and requires a skillset only acquired either on the track or at a suspension/vehicle manufacturer...

generally low speed is for tuning in corners, high speed is for tuning "bumps"...

"This hot Cayman is no blunt instrument. The inside of some corners are seriously bumpy and chopped, yet when the GT4 RS hits them it just brushes them aside. Instead of unsettling it before spinning and spearing you off into oblivion, the Porsche’s stability and traction remind it’s the truly talented one in the car/driver pairing."

not on the 'Ring it isn't.

Larry Cable

yes.
