Hello Guys,

Just got a 2020 C63 Coupe, it rides on the 19s MPSS.

The ride is a bit harsh, it rattles the whole car pretty wildly plus we don't have great roads around here plus tire roar is pretty deafening on concrete or grainy roads.

What bothers me the most is the cat eyes or reflectors on the road, pretty much all the small sharp stuff is felt and heard as the whole car rattles, tire pressure is 32 PSI all around.


This seems to me to be more about super hard bushings rather than stiff springs and dampers... Does the suspension get a bit softer over time? what about tire roar?

Car has about 160 miles only btw so brand new.



PS. I still like the car and don't want a Lexus thanks...

 

You could only compare a 2019+, as the suspension was harsher on the 2015-2018. I had a 2015 W205 and my 2019 is so much better in comfort mode.

If you have it in comfort mode, it might not get any better than that. You might get used to it over time and if not, get a Lexus lol.

 

I have a 2017 pre-facelift coupe and don't think it rides hard at all. No harsher of a ride than any other sporty coupe. What kind of car are you coming from? I think you will get used to it.

 

Might want to increase your tire pressure.. thats pretty low all around...

 

Others here have ended up with rim damage running 32 PSI. I believe the consensus is 36/34 front/rear is your lowest setting not risking damage.

 

No it doesn’t get better.

 

I'm riding on the 19/20 with 33f/32r as recommended for normal load. Yes, I ended up with a bent front wheel and bubbled tire, because I accidently drove over 1+ inch of raised pavement. Not sure higher pressure would have done much. I like the balance between ride comfort and dynamics in Comfort mode. It has just the right amount of damping. Yes, you will feel every bump in the road, but the damping avoids that the car is bouncing around over every bump. I find the damping in the 2019+ almost perfect. Having said that, the suspension will settle over time and loosen up and the PSS ride somewhat harsh. They were crashing over pretty much every bump. I replaced them with a set of the PS4S and it's way different. No more crashing over bumps and all around better ride, handling and grip. The spring rate was lowered in the 2019+ models and the AMG Ride Control software got overhauled. But at the end of the day, this is a 63 and it's supposed to have a firm suspension, bushing and chassis. You won't get E or S class comfort in this car. The suspension has a nice spread between Comfort and Sport+ and it also adapts very well to the driving style, so I find I can even drive normal in S+ w/o being beat up, but when cornering forces increase then it tightens things up. Suspensions are always a compromise between comfort and handling (squat, dive and roll), so in a car like this the suspension is what I call comfortably firm in order to provide enough rest comfort for daily driving, but great handling when desired. Our roads around here are overall quite good, though. It definitely gets quite rough over some of the roads here that are in dire need of being repaved. If you drive on really bad roads all the time, then this car won't do you any favors.

EDIT: FWIW, I keep the suspension in Comfort for slow speed driving around town and long distance highway driving, Sport for daily spirited highway or open road driving, and Sport+ when I hit up the canyons or some other fun road. I actually started to use Race mode in the canyons, which is an improvement over just S+, since it enables Master mode for AMG DYNAMICS as long as ESP is in Sport Handling mode or off. Last weekend I felt in Race mode it did a much better job at maintaining mechanical grip, and it felt more natural and balanced around corners.

 

2019 FL coupe here, ~35 psi all around. I love the feel of the car and as a daily driver I’ve have gotten very used to the ride.

Once in a while I’ll be reminded of its harshness, particularly when I take it in for maintenance and they give me an E class loaner. There’s a huge difference, but it’s also a different segment of cars altogether.

 

That is definitely true. I spent three weeks in a GLB loaner and boy couldn't I wait to get my C63 back. Extremely comfortable ride in the GLB like on clouds, but it wallowed around like a walrus! I have to admit, the best part was not having to worry about where I drove. I could just drive over everything w/o risking any kind of damage. Driving around in the C63 definitely requires more attention and actively avoiding potholes, but it's just so much more fun and rewarding to drive.

 

No it doesn't get better over time but you'll get use to it, trust me and I have a prefacelift coupe which has a very stiff ride compared to a facelift coupe (revised spring rates in all FL models).

As others have said, increase your pressures ASAP. You'll buckle and crack your wheels on those pressures 100% guaranteed (just like all of us have).

 

Yes it is a tough ride, but you will get used to it. I have started to avoid as much reflectors as I can since driving this car.

I got my tire pressure at around 48psi before, and after changing it to around 38/36, I felt it's already "softened" a lot, but still you can hear some rattling somewhere when driving on uneven bricks.

 

Thanks a lot guys... well see if I can tolerate it further. thanks!

 

No, especially for PFL models. I just ordered a set of FL springs for my PFL sedan, looking forward to make my ride more comfortable. Don't know if this has been done by anyone, will post my result once I got them put on.

 

I was thinking of doing this too but some motoring journalists claimed the facelift suspension's reduced spring rates affected handling negatively.

Do let us know how you find it.Read more: https://www.whichcar.com.au/reviews/...ng-term-review

 

There's definitely a level of getting used to it depending on what you are coming from. This is my first adaptive suspension to actually live with on a day to day. I've driven others on multiple occasions, but never actually lived with any of them. Adaptive suspensions behave differently. It felt somewhat odd, unexpected and uncomfortable at the beginning, because my body and brain were anticipating different movements when going over bumps, than the car actually delivered. Now it feels odd whenever I drive a car w/o adaptive suspension. They rock up and down much more and for longer going over bumps, whereas this suspension quickly settles after a bump. The FL is definitely a lot more comfortable than the PFL. The PFL sedan especially is bone jarring even in Comfort mode. The coupe always rode better. AMG deliberately tuned it to be more of a GT and therefore more comfortable for longer distance driving. Back to getting used to it, I kept it in Comfort mode at the beginning pretty much all the time, unless I was hitting up a fun road, but eventually started to feel that it was a bit too loose in Comfort mode for my daily spirited driving, especially on the highway and that's when I changed it to the Sport setting in my Individual mode in combination with AMG DYNAMICS in Pro. It has about the same comfort level in Sport, but it is more dynamic in turns and the steering response is more direct, just the way I like it.

 

I would say that w/o updating the AMG Ride Control software the results may not be good at all.

 

Not sure about this. As often they don't make it clear how the car was setup and once I read that they kept the suspension in Sport and found Sport+ swung the pendulum too far, I had to wonder. First of all AMG DYNAMICS makes a difference depending on what mode you have it in. It affects the handling possibly more than the suspension setting itself. I started to do my canyon stings in Race mode instead of Sport+. Always in ESP Sport Handling mode, so with Race that puts AMG DYNAMICS in the top level Master mode. It handled noticeably different. I always have the suspension in Sport+ in the canyons and unless I'm driving over some really bad pavement where the car just ends up skipping around, Sport+ does a phenomenal job at keeping the wheels on the road, Sport definlty doesn't. Sport is fine for spirited driving on the highway and some open roads, but not if you hit up the twisties.

 

It took my new 2019 C63s coupe about 3,000 miles to past that stiff/harsh break in period for both driveability softness and engine response. It felt like a different car after that break in period. All for the good.

 

I run 38 front 36 rear on ps4s tires, it's not really harsh in comfort mode at least for me. Amg suspensions tend to be more on the stiff side compared to BMW M.

 

I spoke to Carbahn and they claimed that the spring rates are exactly the same. Changes may only be damper tuning.

 

I would say tires make a big difference. I had Dunlop Sport Max GT on before and the ride was bone jarring. I ended up getting the Michellin Pilot 4S about a month ago and the car feels completely different. Almost a little too soft over bumps so I may bump up the tire pressure a bit (currently at 37/33). I have had the MPSS and MP4S on my previous Audi S5 and I can say the MP4S ride significantly better but at the sacrifice of slightly softer sidewalls compared to MPSS.

 

Agreed, I have been saying this for a while now. The PS4S rides significantly more comfortable and I feel it's a better complement to the revised AMG Ride Control. I'm still wondering why AMG stuck with the PSS for the FL, while switching to the PS4S on most other models. Just doesn't make sense, since they revised the suspension anyway. I really wish I've had the PS4S from the beginning and I don't feel the PS4S has lost sidewall stability. I find it handles better under hard cornering and is more communicative. I know much better now what the car is doing and what the grip levels are. The PS4S maintains a better contact patch overall on different road surfaces. It's somewhat more "malleable" I guess.

 

I think my PFL Sedan in comfort mode and even lowered is plenty comfy for my taste. Sport + is sure a bit more stiff but for a performance sedan of this class I would not want it any different way.

 

My 2020 in comfort mode rides really nice, especially compared to the 2014 C63 AMG Coupe 507 that I had.

 

AMG stated the front spring rates were reduced by 10% and the rears by 20% per cent on the Facelift Coupe models. Not sure about sedan, though.
