-Stop telling us the same GD story. We know how you feel. I've seen it myself 4 times at least..
-There is nothing more irritating than a novice driver (like most of us) telling Porsche who produced a 7:04 Ring car that they built a badly suspended car.
-I was taken for a 5 hot lap ride in a stock 4RS at the experience center by an ex IMSA driver and the capability of this car is so far beyond most of our level it's silly.
-All production cars can be improved with higher end suspension. This is a 150K base car. You will not find Motorsport level 2/3/4 way adjustable coilovers at this price.
-Yes, double wishbone style suspension is superior. It was never going on the Cayman. The 911 is the halo car. Cup cars were on struts all the way until 992 Gen. They are still effective on smaller cars.

Enlighten us on the 'how' then.
A GT4RS with 'inferior' strut suspension demolished 99% of the sports car out there...hmm. And in race car trim, pretty much wiped out the other 1%. That's some inferior product.
Multi link, or even double A arm suspensions aren't the be all end all solution to everything. The dampers and springs actually plays a much bigger role than simple suspension geometry.

He has never been on a track.
Yet offers advice on track setup and track tires.
He has never been in a GT4rs let alone driven one.
Yet offers advice on suspension setup for the GT4rs.
And obviously the constant confusion about "why it's such badly setup car."
I feel bad for those that have been caught up in his nonsense advice and think it's legitimate.

for £150k I expected the car to handle bumps better, not on a smooth Porsche owned experience centre !
makes me think you don’t drive your one if you think it is ok !
no after market kit uses 140nm springs and has a 40nm difference front to rear. I know of 4 options to upgrade the 4rs none have a 40nm difference front to rear and all drive better.
I hate how my car handles atm. It’s not right and I have GT4’s, Spyders, GT3’s , GTS’s I own 4 porkers atm and have had 16 the 4rs is not well set up from the factory even if it was a £30k car, let alone a £150k car. The rear springs are too hard and the rear rebound cannot cope with it, it’s just poor on any value of car. So yes I am telling Porsche it’s made a badly suspended car.
why I have no idea, they say it’s not a track car, ok but it cannot handle bumps and dips on a normal road !
look at the new ohlins TTX ring vid and see how misha totally slags off how dire the 4rs is out the box. And how it’s trans formed with a set of £7k dampers.
my £90k 718 GTS SPASM is a much nicer car to drive atm sadly, not only nicer, it's faster on any bumpy road. My issue is do I sell the 4RS or buy some shocks and make it a mega car. I track my 4RS but then it's a understeering mess atm and you have to pick smooth tracks, I track my 718 Spyder is a mega track car with a few mods and 1/2 the price. So atm the 4RS is not making a nice road car and not making a great track car :-( simply due to bad rebound programming ! Its frustrating.
if you think it's ok that your opinion, I think it's very poor from Porsche to have released this car with very little set up R&D.
i do agree that people ie any one who has not driven a4RS should not be posting on here.
it’s nothing like a gT4 to drive and no one but owners know how bad 140nm and a poorly damped car drives like. Nothing to do with struts and double wishbones.
ask Dundon what rates they use , they won’t tell (no idea why) you but I will it’s a 600lb rear spring that is 105nm
look at Ohlins it’s 120nm, SSR, Rocket racing all softer.
only MR stays at 140nm but they up the front another 20nm to close the gap.
the 4RS might even be fixable with a set of swift 120nm rear springs, it just might be ok enough to not have to spend £10k on dampers. A softer rear might make the oem rebound able to cope and it closes the gap back to 20nm front to rear like all the after market kits.

My 4RS understeered too much for my liking until I increased the front camber to -3.2.. I agree that out of the box the 4RS leaves a little to be desired in terms of damping and spring rates. It's sublime on smooth tracks like Anglesey, Silverstone and Donny but bumpy Oulton is a different matter !. I think I was as fast or maybe faster there in my 718GT4. I'm still figuring out whether or not the problem on bumpy surfaces is a result of being over sprung at the back or underdamped. More likely a combination of both. The PASM can't cope with 140Nm/mm rear springs especially on the rebound at high speed. An experienced racing driver can drive around this but hobby track guys like myself find it erodes confidence making us back off the throttle on bumpy bits,
However it's still my favourite Porsche of all of the ones I've ever owned and just a set of top quality adjustable coilovers from achieving near perfection in my view. I'm currently favouring having a slightly softer rear springs(120Nm) over the over priced Manthey ones with even stiffer front springs. The ideal rates seem to be 100Nm front and 120Nm rear imho.
For serious track work the 4RS needs both front offset camber plates and longer rear toe links at the minimum and then upgrade to better dampers if you prefer..
Great video by Misha driving a 4RS with TTXs showing how the car is completely transformed. It's what I'd fit to my 4RS if it was available with front lift but sadly not.
I'm back at Anglesey for the second time this year at the PCGB track day on July 11th so will see how things go.

all different ones, and what ever suits the track and road on that day. I don't stick to a set PSI as all tracks are different and summer road use is not the same as winter road use. Also you did not ask what tyres I used, so knowing my PSI without knowing what tyres and cambers or track is not the right question to ask ;-)
I can be 26 psi front or 32 psi front and 28 psi rear or upto 33psi rear. it's what ever works with the smoothness, temp and grip level of the track on that day of said track. A cold bumpy track is lower than a warm smooth track. Road use is lower than my track use. A high grip track higher than low grip track other wise it rips my tyres apart. Tyres PSI will not fix the firm rear spring and miss programmed damping ! that I will tell you for free.
ATM I run as low as I dare every where just to get some give in the rear of the car. If it's a hot very high grip track I have to up the PSI to save the tyres. My issue is keeping the rear tyre in contact with the tarmac be it road or track once you push and ask more of the car.

Just to clarify I have have never found my 4rs in the slighted bit dangerous even on bumpy roads just my confidence to push harder is eroded. I can also reiterate that it's only on some bumpy sections where the problem arises. A set of either MR dampers or other more sensibly priced dampers is only the icing on an already very delicious cake.
The 4RS is a very special Porsche due to the supremely exciting drivetrain along with the very compact dimensions yet two very useable trunks. I much prefer it over the 992RS for these reasons along with the cost of buying and being more fun and challenging to drive hard. A sure fire future classic imo
