The C43 rolls like a pig during cornering, any solutions?




Did MSS offer choice of spring rate? I think a higher spring rate in the rear for the Estate may improve the Estate's driving experience. Let me know when u wana get rid of the MSS. I may be interested...

A couple of local Estate owners has custom Hyperco springs and swears by them. They used something much higher spring rate than the H&Rs. I forgot the specs tho...

Drop in lower center of gravity as well as a slight change in camber. Start small then work big try lowering first.
Definitely agree with TModelles post. With past cars, adding in sway and strut bars really stiffens up the ride and improves body roll. Wished some were available too for the 450.

Anyone on “485” Sport Suspension option on a C300 or C450?

All I could find for the C450amg/C43 in regards to reducing body roll.
Front strut bars on ebay.
Mercedes Benz C43 W205 Ultra Racing Front Strut bar 2piece 3.0T 4WD 2016 https://rover.ebay.com/rover/0/0/0?m...2F323772090518
Not sure though if the front (and rear) strut mount locations is the same between the C450 and C43.
Anybody know?
If you have 18" you have a good selection of non-MO tires to choose from - if you have 19" then "standard" tire selection is more limited
The design of MO tires is that they have a stiff and unforgiving sidewall and YES in all curves at speed - even swooping gently curves - MO tires will feel like "driving a boat" - with excessive "body roll" because the tire sidewalls only flex up 20%-25% of the height of the sidewall - even thru the electro-mechanical steering you can feel the push back on curves.
Once you switch over - then you can begin your pursuit of suspension improvements.. remember MO/Extended Mobility Tires were developed so car manufacturers could start delivering cars with 4-tires/wheels and not have to have a 5th/tire-wheel.. MO/Extended Mobility Tires were NOT designed for performance...
A little factoid.. Mercedes Brand Immersion Training - which runs two classes a week like 44 weeks a year - AMG there run "standard" high performance tires - MO/Extended Mobility be d*mned..

Guess somebody has to be the guineay pig and try them and report back if its noticeable or not.

they also produce other parts that might be more useful though
don't feel that much chassis flex in the sedan honestly. car just has a high center of gravity - just changing the stance and alignment have made really good improvements. Could never be stock now.
The wagon does ride like a boat~Ultra Racing has some parts...

and put that order in for the KW V3's~

For some reason the link isn’t working (404 error). Looking for the other bracing arms since there is indeed already a front strut bar in place on the C450 don’t really think it’ll make much of a difference like TModelle said.
Sounds like a member just installed some rear ones and the company through eBay hadn’t responded to my messages.
Thanks in advance!
Without changing shocks/ springs or fitting ARBs, the strut braces alone WON'T reduce body roll, but will reduce chassis flex.
Body roll is determined the ability of the car to rotate about its longitudinal axis. That's determined by how stiff the suspension is and the presence of ARBs, and the ride height.
Strut braces will stiffen the chassis and reduce flex. This will allow the suspension to control wheel movement more precisely, improve steering response, and maintain the correct camber under load more easily.

In Audi-speak, the RS wagons always outhandle their sedan brethren. I know this first hand, and many who have driven these high performance wagons for the last maybe twenty years would agree.
Those who’ve driven the C43 wagon and the C43 sedan on a regular basis will know that there is not much between them, you will forget that the rear has a longer roof line if you weren’t reminded everything you looked in the rear view mirror. In fact. The weight balance of the wagon is superior in my opinion, with a slight rear bias.
In this thread, I’m not taking about coupe vs sedan vs wagon. They are all C43 and should be treated as C43. Otherwise Mercedes wouldn’t have badged them as such. The handling of the C43 platform as a whole leaves much to be desired if one comes from Audi/BMW ownership and experience. I’m looking to improve the handling of the car (and not replace the car) and I’d like to start by reducing body roll, and perhaps dial out some understeer. It needs bigger tires in front, I’m surprised Mercedes have a staggered setup for an AWD car.
