Nurburgring might record all those parameters but only Mercedes have actually made all their alignment settings public. Porsche should learn from it in the future.

Its interesting... I owned a 992 GT3 and thought it was too stiff to drive daily for sure. where the 991.2GT3 kinda felt like you could drive it everyday. so that was a surprise for me. lets be honest, its not like you can test drive these before you buy one... right?
as for the RS badging, yes, it makes it excusable. I just hope that there are aftermarket options for maybe swapping in some more reasonable feeling suspension.... not because I dont like race car type feel... I totally do but there is a place for that. The track. but 90% of the time, ill be driving on backroads, etc. so... not exactly the best fit I suppose but ill figure it out. owning this special thing, is pretty amazing in itself. maybe that is enough to overlook the compromises?
I just wish mag ride suspension was used instead. I mean, the Ferrari 458 had it years ago and that thing not only rides great but is very capable on track! But then again, cost and reliability become factors at the design level. Either way, I am excited to get this thing... I just want to use it all the time and bums me out a bit that I know I wont be able to.

No confusion, 992 gt3 stiffness is slightly more than 991 for sure, but the 991.2gt3rs is noticeably stiffer than 992gt3 as well. 992 gt3 is somewhere between 991.1gt3rs and 991.2gt3 from my experience.

It also makes a big difference if you go sofas over the buckets.

Also, sounds like the gt4rs might be stiffer than the 991.2gt3rs which is the stiffest porsche I have ever been in by a good margin, even the 991.1 rs

welikethetrack

Did you have the buckets in both?

blackmist27

yes. I dont think you should option an RS without buckets...

welikethetrack

I understood you meant a normal 992gt3 and 991.2Gt3, not RS...

The spring rates in the 992 GT3 are about double the stiffness of the 991.2 GT3’s spring rates (and about the same as the 991.2 GT3 RS). Downforce in the 992 GT3 and 991.2 GT3 RS are also about the same which is the reason for the stiffness. Same laptime too…

I didn't post it to help you compare this to the 992 GT3's stiffness on the road. I posted it because it was the first US based comparison that "I" found, between track and road, in the US, by the same reviewer.

And don't forget, there could potentially be a significant amount of compliance which could be brought in with stock struts by adjusting PASM settings via aftermarket. If it hasn't already been posted, 992 GT3 spring rates are ~625lbs, per the Harris video, if I remember correctly.

blackmist27

I had actually watched it before seeing your post.
but that being said, I am just sharing my thinking in wanting to understand the road manners of the GT4RS because I have an allocation. Not sure if you meant for your response to sound a bit snappy but it comes off that way. I was just trying to figure out how to compare the stiffness to something else. How can you take a subjective opinion and get an answer? you kinda cant. but if you can say GT4RS >GT3 in terms of stiffness, then it gives me a sense of what to expect. make sense?

Get the 4RS. If it’s too stiff for your liking, talk to MCS and update the suspension or sell it.

My response was to confirm that me posting the video was not specifically to address your concern. Had I been following your posts, and found the video to provide some insight, i would have commented. Take it how you will. Conversely, your response could have been taken as egotistical, but I didn't.

That said, my follow-up post regarding spring rates for the GT3 RS was to give a reference point, if that information had not been already known/posted, but again, even if spring rates are the same, PASM settings can have a drastic effect on comfort. Also, aftermarket springs will probably be offered, if softer are desired.

The 992 GT3 RS is mostly about active aero for the first time. It's going to have huge downforce, but it will be able to mitigate the typical aero drag that comes with big downforce by reducing the front and rear aero when blasting down the long straight at the Nordschleife (top speed there will be significantly higher than before).

The 992.2 will add some power (either 4.0L or 4.2L from the 992.1 GT3 RS and 992 limited models). I expect the power of the 992 RS or 992 limited models to get up to 550PS NA and it would be typical for Porsche to slightly detune from this level in the 992.2 GT3. So maybe up to 540PS in the 992.2 GT3 (at most). So, 30hp bump, a little more suspension tuning, new tires, etc. will deliver a little more performance. Generally, the ".1" of a GT3 generation is a significant chassis change and the ".2" is a significant motor change. The 991.1 was both, since they had to retire the Metzger motor for regulatory reasons.

Maybe the 992.2 GT3 will adopt some form of active aero as well (hopefully without sacrificing the entire frunk that looks to be happening with the next RS).

Agreed...have to drive it first. I spent 2 years adjusting PASM settings alone to get my 981 where I like it...and actually biught stiffer springs for a car i initially thought was unnecessarily abrasive.

Alternatively, you could also see if stock GT4 springs can be used on the RS to soften. People have reported using the Swift kit at ~425fr/525 rear, and find it fine for extended street driving.

MCS won't help much. My spring rates are VERY similar to the GT4RS and with my 2-way remote dampers I had to crank up the compression and especially the rebound to keep the dampers from bouncing off the springs. MCS dampers are designed for track use and are motorsport derived.

MCS actually even suggested to me to go higher on the spring rates to keep it "off the spring", but I do not track, so it makes no sense for me to do that.

What MCS dampers do is smooth out the sharp impacts better than OEM, and you can better dial in the damping, as Porsche's damping curves are not very good for anything but smooth roads. They have too much compression and not enough rebound. They also get rid of that "pogo stick" effect of the stock PASM, but make no mistake, my car still has a decent amount of vertical motions on the large dips and bumps at freeway speeds. It it far from a complaint ride at speed and MRC is still superior as a dual personality.
