Having driven the car now for about a month, I've found that the C43 rolls at an extreme angle during cornering, hardly the sporty handling I hoped it would be. Are there any aftermarket solutions to this? Uprated sway bars, perhaps?

I think it handles good for what it is. Two things you can do. Change the tires to a non run flat performance summer tire. You can lower the car a little bit.

TModelle

Thanks for the advice, although I am not sure how running non run flat tires is going to help it roll less, but yes, I will lower it. This car runs too fast for its handling capability, and handles like a boat!

It would be a stickier tire. Lighter tire. Lowering I would consider the Renntech spring kit. I have had KW on my Audi’s and they never held there ride height. I had HR as well and the ride was terrible.

TModelle

Why would a stickier and lighter tire make the car roll less?

jim04clk

The tire compound is much more stickier. Better for handling. What state are you from. I’m in NY so like the all season tire.

TModelle

Referring to roll, I think stickier tires will make the car roll even more. I'm running factory Conti CSC 5P MO.

Get rid of these tires as soon as possible. Read some of the reviews here on tirerack from other Benz owners. They split sidewalls like crazy over regular potholes.

I'd recommend Michelin AS3+ or Conti DWS06 if you need high performance all seasons.

Please no more tire recommendations, I am looking to reduce roll. Would be great if anyone had suggestions to reduce roll.

Perhaps you should be more specific and mention that you are talking about body roll. You are getting tire advice, because tires can roll over in corners. It's when you start partially driving on the sidewall during hard corners. This can be avoided by increasing negative camber for example or using higher inflation pressure, or better tires that maintain their shape better under hard cornering. Body roll on the other hand is proportional to the softness off the suspension, and the way to reduce it is to stiffen it up. Lowering the car to lower the center of gravity and stiffer sway bars. This kind of suspension modification will impact ride comfort, though, and messes with the adaptive suspension. At a minimum you should take the car in and have an AMG specialist adjust the suspension settings afterwards, so the adaptive damping works properly with your new setup. The tires are a good start, because you may in fact be rolling over your tires. If you start seeing wear past the tread pattern on the sidewall of the tire that will be a sure indication that your tires are rolling over. I'm not sure what you were expecting from a C43, though. It's meant to be a more livable sporty daily driver. If you want more hardcore handling then you would have to step up to the C63, especially the coupe because of its wider track front and rear.

TModelle

Thank you for your insight. Perhaps you could read my first post and you can see that I am referring to body roll, sway bars and not tires. I will explore lowering the center of gravity. However, unless you can suggest that there exists aftermarket/uprated sway bars for C43, this doesn’t seem like an option.

Also, unless we are driving very different cars, I am not aware that the C43 has any adaptive/active suspension, but just damping behaviour that is driver selectable only. Comfort, Sport and Sport+, and the damping is fixed once the mode is selected.

superswiss

I should have phrased it differently. It was clear to me that you were talking body roll, but it seems everybody else was thinking tire roll. I haven't looked into the C43 aftermarket and if anybody is offering upgraded sway bars. It's challenging with adaptive suspensions to really do much, w/o a complete conversion and getting rid of the OEM electronic damper control. Places like RENNtech offer essentially mostly aftermarket springs that lower the car and supposedly improve handling, but in general just replacing the springs w/o matching dampers is sub-optimal. You can only hope they did their best. Ultimately, if you start messing with the suspension w/o doing an overall re-tuning to make sure the electronic dampers still do their job well with the new setup you end up with a hobby setup. All these lowering kits are mostly for looks to be honest. If it's just a minor drop and the spring rate is not that much higher than they work OK with the OEM dampers, but just keep in mind that all components of a suspension depend on and complement each other. Change one and you might end up with a crappy ride.

Most of these guys never been in a C43 Wagon so they don't know what you're talking about. The wagon does ride like a boat~

Ultra Racing has some parts...

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

Awesome! Thanks!! And so close to home....

Always a pity if people get forced to buy a car! I feel for you, thats inhuman! Imagine, in a better world we would be able to testdrive a car before we buy it! Just imagine how good that would be!
You could actually TEST the car BEFORE you buy it! Wow, someone should implement that.

xX G Xx

You would be surprised how many owners didn't get to test drive the particular model of the car before he/she bought it outside of US...

The country that I lived in now didn't have the C43 wagon, or coupe, for test drive. I don't remember there was a c43 sedan for test drive either. Or you have to wait til the test drive car gets pass around to your town in a few months...

Especially the wagons here. I would say most bought it w/o test driving one and was disappointed with the handling.

Malar

Then just don't buy a Car from a Dealer that can't provide you with a Testcar? I testdrove mine twice, different cars with different options. Then a third car which i got for 7 Days to test, only then i started to talk with the Dealer about maybe buying it.
If my Dealer can't provide me that Service, another Dealer gladly will. Common Sense.

Anyways, getting off topic and don't want to get in an argument here. All I'm saying is buying a Mercedes in other parts of the world is a little different from that of US, Canada, and other countries where there are numbers of dealerships competing and large inventories to pull from. Some countries have only one authorized dealership and almost no inventory. Cars are custom ordered and built. You basically just get in line and pay retail price.

I waited 7 months for the GLE43 coupe and bought the display C43 coupe without test driving. And all @ 200% of US prices.

Malar

I live in Switzerland where we have only one authorized dealership. The Sellers there all gladly take the provision if you buy the car from them and not the other dealer, so theres still competition.
There is Inventory, just search a Dealer that isnt lazy and organises a Truck that ships a Car with the Specs you want near you so you can testdrive it. You pay 100k for a Car, why would you be content with anything but the best service.

lowering does help. roof line is high on this car. at a little less than 26 inches ftg the car is probably has 20 - 30% less roll.

those reinforcing bars don't look quite stout enough where they actually connect to do much. need more than a flat bar on one side of the connecting area with a bolt to reduce flex. but i'm sure installing the whole gambit would help marginally.

Conv_GSDriver

Other than lowering as already stated, sway bars or other suspension stiffening items like strut braces but you may sacrifice ride comfort going this route. I'm assuming ride comfort is not important to you at this point.

TModelle

In some parts of the world, there is only one dealer and there is no test drive. Most of these cars are bought unsighted. But anyway, off topic. How do I reduce roll? I think only KW V3 might be the solution at this time. I will try lowering it first. I have MSS and KW HAS on the way.

superswiss

I didn't realize you have an estate/wagon. Makes total sense now. That's not the body style to get if handling is important. It's a tall box on wheels. The coupe has the best handling having the lowest roof line, followed by the sedan and then the estate. Coupes generally have a lower roof line and a wider track, both helps with body roll and handling in general. An estate/wagon is great for practicality, but that tall box is not doing handling any favors.

If you dont have run flat tires what does one do about not having a place for a spare?

superswiss

Tire mobility kits and/or roadside assistance. Higher level performance cars such as the C63 etc. neither have runflats nor a spare tire. There's often not enough space or a full size spare is impractical due to staggered wheel setups and space savers don't clear the larger brakes and nobody is gonna put up with the downsides of runflats at that level. These cars typically come with an air compressor and a can of tire sealant in the trunk for emergencies. I'm personally not a fan of the tire sealants as they goo up the entire inside of the wheel, so I carry a mushroom plug kit in my trunk, but I've yet to need it. The reality is if you regularly check and adjust your tire pressure and perform a visual inspection of the tire and replace them before they reach their wear limits or are otherwise damaged, the likelihood of a complete flat is very small. Most of the time it's a nail or screw stuck in the tire accompanied by a slow leak and the car can be driven to the next tire place to get it fixed. I've had cars with no spare tires for a while and it's never been an issue.
