Only a few hundred cars being produced this year; everything else pushed to calendar year 2023. Lots of pissed off potential owners on corvetteforum.com saying they are giving up on the car and wondering if there’s something intrinsically wrong with the drivetrain as the reason for the current delay. Oh; and the BS ADM/flipper games of course.

Was certainly unsettling when they transferred all the engineers from the Z06 team to the EV segment, long before the car’s release…

Porsche's Bilstein dampers are pretty much fitted to all their cars from Cayman, Boxsters, Cayennes etc and have different maps for different cars depending on priorities. These dampers are no longer good enough for their high end GT cars as I've around race circuits in the same 991.2RS WP as mine but fitted with MR KW 3/4 ways. The improvements are truly transformative and really highlights the PASM's limitations.
I hope they've fitted different dampers to the new RS otherwise it won't be as good as it could or should be.

the 992 is like the iPhone 40. Its ridiculous to suggest Porsche is going to get it right with the iPhone 41Pro

I hear where you you're coming from - but you're off beam.

Porsche GT cars are designed to be genuinely track capable - the consequence of this is they must be stable and handle bumps and minor perturbations up to around 280-290kmh e.g. Dottinger Hohe. A minor bump at 110kmh may be a major problem at 250 kmh. Thus damping and spring rates are designed to be safe at these high speeds, superimposed on this is control on piston travel length - if you hit the bump stops/bottom out at 240kmh you may be thrown off the track.

The reality as speeds increase, downforce increases and as a result spring rates must go up to balance downforce and impact force transmitted through surface imperfections. The result is you end up with suspension that is designed to limit travel 90% of the time over a piston length of ~ 2 inches at well above road legal speeds. The knock on effect is at road legal speeds piston movement is small and changes to damping within the spring rate calibration has less room for manoeuvre. In other words the car "jiggles" - this is not a problem with PASM its a problem with the design envelope of the car.

In other words, if you put your foot down and drive at speeds more towards the cars track envelope you will find the damping is fine.

My car has Corsa tires. About 2000 km on the clock now.

The tires are quiet when compared to Cup 2. Read up on them after I took delivery to see what I was in for, they actually have noise cancelling tech in the tire. Jet engine spooling...could not disagree more.

@RUF RS Has a point. Expectations versus reality. Touring name might set somebody up with different expectations but it's a GT3 same as the wing car.

Agreed

I fully agree with the comments about downforce and suspension travel and spring rates having to compensate for that. What I dont understand is why touring has to make the same compromises? Touring does not have the same amount of downforce and as such should get suitable springs and suspension tuning for its needs. If that happened, most people would be happy.

I owned a GT350 with magride. I think it's ok for what it is...the difference between comfort and sport is very large and noticeable. Even the realtime adapting is noticeable, but it also feels artificial and slightly disconnected. I think Porsche does damping so well, i wouldn't change it to magride. BMW on the otherhand...their sh*t sucks, dump it and go magride all the way haha

The thing you have to remember about Magnaride is that the technology and hardware are the same across manufactures, but it's the software tuning that determines how well it works. I have had it in an Audi TTRS and Camaro SS 1LE and both Audi and GM does the tuning very well. I can't comment on Ford as I have never driven one with it.

It is definitely different feeling than a passive damper, but that doesn't make it artificial. It just does things that a traditional damper can't do, like give you 100% damping lock up and stop a rebound movement in its tracks, then relax it .0001 seconds later. It operates at like 1000 times a second or something crazy like that. The newest version of Magnaride, which is only used on the C8 and Caddy performance lines, also now use actual data from sensors rather than prediction software to make adjustments.

Porsche damping is definitely better than BMW (hell Honda and Toyota do damping better than BMW these days), but Porsche isn't perfect either. Both the GT3 and GT4 cars suffer from a pogo stick effect on the front axle, and at least on the GT4, they underdamped the rebound in both modes.

That effect is gone with the double wishbone on the 992 GT3.

how do you know this is the case??

Had the exact same experience driving mine through the canyons around SoCal. It’s down right scary driving at speed. The car would jump and at times feels like the rear might get airborne. It’s white knuckle scary. For road driving like this, I agree. It’s under damped and over sprung. Epic on a relatively smooth track though. Feels like I can drive my M2 CS much faster because of the suspension. At least on varied canyon roads.

My personal feeling with all versions of the GT4 (that I've owned or driven on track and street, except the 4RS which I have not driven yet) is that the entire chassis felt over sprung and under damped. It's one of the reasons I sold my 981 gt4, I really didn't like the chassis feel or compliance. I don't feel this way about the 991/992 gt/rs cars. The damping is much better with those, the 992 being very good. And miles better than in my long-term 997RS with the stock dampers - though it's had onlins ttx on it for so long I've not forgotten how bad it was.

I had a GT3 and can relate, my hands would sweat from death gripping over bumpy backroads. I currently have a GTS 4.0 with SPASM, and it's perfect for backroads, soaks bumps, no tramlining, i prefer it greatly over the magride in my GT350 (which wasn't bad), but SPASM is really quite perfect. But I understand your point, i haven't ridden in a Ferrari with magride, so I can't say how SPASM would compare with that.
