no, the tree root only has issue with CGT.
all other cars fly over it fine.
it will go airborne but will not twitch when landed unlike CGT.
992 is very easy to go fast...
it def has many issues, but strangely they don't bother me.. and you know I usually get very irritated with tiny issues.

Chris Harris when test drove a 992GT3 Touring on some bumpy UK roads said exactly the same thing. In his video he makes a strong specific point on the 992 Touring being underdamped and oversprung just like what JVO said. Another well known and very reputable UK guy Harry Metcalfe said exactly the same thing when he drove a 992 GT3 on similar bumpy UK roads.
So we have three highly reputable experienced motoring journalists say the same thing in that the 992GT3 is under damped/oversprung. Pretty much conclusive IMO.

CH mentioned it was at low speeds around town. Once youre moving he said its actually more comfortable than his 991.2 touring.
I tend to agree with that take. I avoid city driving as much as I can. Also did with my 991.2. GT Cars arent designed for low speed city driving. TTS would suit that situation better

I'm obviously not capable of pushing the car to his levels but his comments are not my experience. Perhaps there's something wrong with his car.

Let's see how the next gen tuning on the RS is. Seems likely that the wishbone setup is so new Porsche is learning how to make it work in all situations. On the track, it feels great, even soft. In hard corners around town it also feels smooth, even over a very rough surface. In a straight line at medium speeds, it's bouncy and clearly underdamped. I'd bet the RS and .2 will be vastly improved in bandwidth, just like the 991.2RS was vastly improved over the .1RS.

Laughable that he wouldnt consider tire pressures

Just returned from one of my Sunday morning country road drives. It is a quiet agricultural area, lo to no traffic, lot of curves and shape. I was in sport mode and driving at the “fun” speed. Great fun indeed, however there is a section of road that is very irregular, pavement good but it is lumpy and bumpy. So I transition from ideal road to this section and he car starts jumping and pitching. I am using the full road and cheating in the middle. I had to back off or risk a lurch to the shoulder and trouble. Yes the suspension is very hard sprung. My 991.1 GT3 was more compliant and would better absorb the type of road irregularity. Sure I was going at a frisky speed but it got ready to bounce right off the pavement and I was working the wheel more white knuckle than track driving. I make no complaint as I like the suspension set up and especially the front end steering action. I know the limit and back off when the over sprung condition is trouble. So I understand what the Brit journalist are saying as my country road is in the same nature. So let’s say you could go 90+ but you better hold it to 65-70 or have a hop into the bushes.

He may have considered the pressures and saw that they match the pressure recommendation on the door jamb. But its perfectly reasonable to question whether he saw the 5 psi lower recommendations buried in the Owners Manual for Performance driving.
Also, the tire pressure gauge on the dashboard typical reads 2 psi lower than actual pressure, in my experience (so actual pressures 7 psi higher than Performance recommendations - which is enormous difference).

There are PASM parameters which can alleviate that behavior...again, its a question of whether or not the appled settings for said behavior(s) is implemented. The speed at which one is moving where the car is more comfortable can be set.

The trouble is the Touring uses the exact same spring rates as the winged GT3. At certain speeds driving in a straight line over heavily cambered, rough and bumpy roads the car feels underdamped in relation to the increased spring rates. No issues on race tracks or smooth roads. I wonder if Porsche have changed the dampers on the new 992RS since the spring rates are 50% more again compared to the GT3. Matching spring rates to dampers is a black art especially electronic variable ones. Better off using the Manthey KW 3/4 ways IMO

I might get flamed for this but....
IMO, I think Porsche is losing its edge in the suspension/damping game. Similar to how at one time BMW was the Ultimate Driving Machine, it has not been so for a long time now, yet people still buy into the marketing of it.
I said it earlier, but it is worth repeating, MRC (Magnetic Ride Control) is where it is at technology wise. It allows you to have your cake and eat it too. Similar to BMW, Porsche sets up their cars for smooth roads only and that is where they shine and feel amazing. HOWEVER when the roads turn to crap and the suspension gets a good workout, THIS is where great damping tuning shows. BMW has not had it for a long time now and Porsche is trending in the wrong direction.
I was severely disappointed with my stock 718 GT4 PASM damping.

Im also interested to see the RSs time without MRC as well.

Perhaps a DSC tuning will help with low speed harshness? It did on my 991.1

Why have we been promised a C8 Z06 Nürburgring lap time for over a year (and most recently teased 8 months ago) and still no lap?
Surely with 160 hp more and 115 ft-lbs more torque than the GT3 and RS and MRC suspension with Mid-Engine chassis and huge sticky tires, it should be much faster??
So far, 7:12.64 (no mention if short or long version of the lap, but ~13 seconds slower than GT3 even if long lap):
