I had a 2017 C63 coupe and drove it for 6 months , the V8 engine performance and exhaust sound were fantastic but the harsh ride was unbearable on long rides . To give you an example ;my 991.1 GT3’s suspension was better than the C63’s and the porker is a track legal car !
when hearing of the face lifted C63 and that they have made the suspension better , I went and put a deposit on one and test drove one for a short distance ( I honestly could feel it was better by around 10% ) ...but even though my order comes in September , I am still worried about finding out that the ride is still harsh after driving it for distances .
The cars perforamnce and sound and sexy coupe look is what I love , the suspension is a worrying factor and would love input from new C63 COUPE owners

On the contrary, big difference depending on what it was set at. Look at the picture above. For example for the 19/20 wheels the pressure is 230kPa(f)/220kPa(r) at the low end for up to two passengers, little cargo and max speed 250 kmh to 320kPa(f)/330kPa(r) for a fully loaded car and top speed 290 kmh. That's a 100 kPa difference or 1 bar. 1 bar is atmospheric pressure, so we are talking 2 times atmospheric pressure at a low end vs 3 times atmospheric pressure at the high end. Running at ~3 bar by yourself and no heavy cargo will make for quite a harsh ride when you should be running at ~2 bar per the recommended tire pressure. This is typically what happens here in the USA. The sticker on the door frame only indicates the highest full load tire pressure, so most people and unfortunately even shops inflate the tires to that pressure. It'll result in improper tire wear and unnecessary firm ride.

It's interesting that there is no-one in this thread commenting on different spring options - are there any that will take the edge off the primary ride? I live in Germany so I want to run reasonably high pressures as seeing 150Mph+ is not uncommon for me.

I have a 2019 c63s coupe I got last week..everyone that’s been in my car says it’s very comfortable and not harsh. I drove with my buddy who is 300lbs and 6-1 and he said the performance seats are soo comfortable he could go across country in them no problem. My gf that is 5-3 and 110-120lbs says the same thing how smooth the ride is and how comfortable the performance seats are. I absolutely LOVE the ride!!!

I wouldn't worry too much about "improper tire wear" on these cars though because it's so bad anyways. You're lucky to get 5000 miles from the fronts due to super-aggressive camber. Mine (and a lot of others going by the other threads here) were showing cords on the insides at 7000 miles. I'm about to have to order another set of fronts here at 11k.
