W204 C300 Suspension Upgrade

Hi Everyone,
I have a 2013 C300 4matic Sports Sedan (has 73K Kilometers on it), Just was thinking about upgrading the suspensions without lowering the car or compromising the comfortableness. Now keep in mind my car has a very stiff suspensions to begin with. Should I buy the KW or H&R kits? Or do you guys have something else in mind? BTW It's a daily driving car and lowering is not an option for me. Roads are very very bad where I live.

Thank in Advance

Does it come with like a kit? Or do I have to buy the springs separate?

Aka , Eibach /Bilstein B12 kit .
Bilstein B8 dampers with Eibach Pro kit springs.

​​​​​​Since your original Sports dampers should be in good condition I'd just recommend the Eibach springs.

In my case, the original springs were still good. The bill said struts replaced in front. Not sure about the back. The OEM shocks had almost 90K miles on them, so they were probably past their use-by date.

in most cases the original springs are perfect, unless you want 200km/hr+ handling, its not like upgrading a suzuki sv650 suspension system- ie. from a manufacturer that designs for a low speed and lighter operator/ load.

Ironically you could end up with a slower vehicle on the street as a result! even if it feels faster!
Brakes would be the first thing I would upgrade.

if your looking for height and dampening adjustability , you cant go wrong with a nice set of coilovers . Personally i will never run lowering springs on any of my cars.

]I always get questionable info on whether a certain strut will fit my 4matic. Here is what TireRack says about this Bilstein part number.
  • FRONT
  • Housing: Strut Housing
  • Non Adjustable
  • Manufacture Part #: 35-170815
  • Note: Front Fitment. (Performance) IMPORTANT NOTE: EXC. 4MATIC.
