Upgrade stock springs to sport springs?
Hi guys, first post on here !
I have a 2015 C300 4MATIC with the standard 17in. rims and the Luxury Package.
The ride is very soft and comfortable, which is great and all, but I was looking to upgrade it so that it’s much more stiff and sporty.
Would I be able to switch my stock springs for a tighter set of springs?
As everyone seems to love there is the option to switch for the H&R springs or the Eibach springs, but would any of these make the ride more stiff?
Thanks so much !
I also am driving with Michelin Pilot Sport A/S 3+ with the air pressures at 37 front and 45 rear. 225/50R17 all around.

Warning Lots Of Info Lol
First question is what is your goal? Is it for Looks? Track? Just want to lower it? What’s your budget? Are you a DIY person or paying someone to do the mod.
Cheapest option is to lower with springs, coilovers then air suspension.
we both have the same model car so this should be helpful. So just an example right now your car is at a 0/10 zero being softest/comfortable setting. 10 being extremely stiff god awful lol
things that will make that number rise is, wheels diameter (inches) the higher you go the stiffer it gets ie less sidewall less cushion.
say if you want to just lower the car with either company lowering springs and use your stock wheels, it will get stiffer to maybe a 2/10.
^ plus 19 inch wheels with a tire size 235/35/R19 it will go to a 4/10, 20 inch wheel 5/10 etc....
Note* for both companies, when they say it will lower 1.5 inches front and rear that’s for our model and when it’s lowers 1.2inches front and rear that’s for the sport model which is a little lower than ours to start.
if you want to slam to the to the ground get coilovers, you can adjust height and dampening(soft/hard) But a set will run around $1000 usd plus shipping etc plus install
best of both worlds is a air suspension kit but that’s in the $3k-4K and higher.
anyways I have a set of used H&R springs for sale soon just have to take them off the OEM struts. I’ll post it for sale later if you’re interested

I should’ve addressed that lol!!! To that, not all cars are the same, I’ve never exp anything odd or squeaky. My stock struts were ok before and after. If you already have a pre-existing clunk then these won’t help lol. More times it’s ball joints, control arm/bushings in general are the cause but every1 blames the springs lol, just have them installed properly and it won’t be an issue down the road literally lol. I assume u no longer in warranty period etc so most likely it will fail sooner or later. Again if budget is a slight issue just get the springs and call it a day, others would get a strut upgrade from Bilstein for example but those plus springs are close to coilovers. Springs are a great cost effective upgrade, and you won’t scrape or have clearance issues unless u get giant wheels and tires and that a different story. And your welcome!

wow $600usd? I got mine done for $200CAN so $150 usd? Lol fronts are easy if u have the right tools, 3 bolts on top, 1 bottom. Rears are just 1 bolt, pop out then in. I just didn’t have a lift and didn’t wanna do it lol. Some shops will raise the price just cuz it’s a benz or bmw anything German pretty much. It’s hard to find a fair priced high quality service but once u do 👍. But if I got a $600 bill, they hate me lol

Idk what to tell you, times are rough and people trying to make a lot of money fast? Money aside, 2-3 days? Either they’re really busy or they don’t know what to do :/. Mine took less than 2 hrs. Assuming nothings seized. The alignment should be taken a few days after install. Let the new suspension settle which it will go a bit lower. If I were you and have a couple friends not in quarantine buy a case of beer and install it together. As long as you have spring compressors for the fronts. Or keep shopping for a better price might have to go else where. GL

Sorry for being late to the post, but I'm looking at purchasing a C300 Sport and was wondering if there is anything to make it corner flatter as in stiffer roll bars. I looked at H&R and they didn't have anything listed.. But is there any difference in that part of the suspension to the AMG? I used to have a 2000 C230K Sport and I was able to upgrade the Sway Bars to AMG Sways and it made such a big difference in cornering. I was wondering if I could do the same with the W205 Sport….
Thanks in advance..
Thanks in advance..
as to a difference to the “c63” yes, to the c43 no.
if you don’t wanna lower your car, that’s your best option for now,

Thanks for your quick response. I'm in the US.
I looked at both Eibach and H&R but neither sells a sway bar upgrade kit for the 2017 C300 Sport..
I was hoping to upgrade to get a flatter ride. I'm not interested in lowering the car or making the suspension stiffer. I just wanted less body roll..
I'm coming to the conclusion that maybe the upgraded sway bars on the Sport model is the same as the AMG C63, but it's the rest of the suspension that's completely different.

there are many chassis bars available in the market but they work differently from sway bars.
For sway bars, only H&R has them, and i believe it's only for the RWD variants (rear would be the same for 4matics, but not confirmed for front sway bar).

I bought Eibach sway bars before for a 2000 C230K and they were identical to the AMG bars for that year/model other than painted red and had Eibach instead of AMG stamped on them. Same thickness. I'm completely aware of H&R offering them too. I was just lucky to get a discount on the Eibach when I was in the market for them for that car.
I'm thinking that for the years I'm looking at that the Sway Bar for the Sport model is the same thickness as the higher end AMG43 and AMG63 sway bars.. I'll probably call the dealer and ask them what the part numbers are and look it up that way, only OEM pricing usually is ridiculously expensive.. ;-)
But thanks..
But won't those chassis bars improve handling and lesson some.amount of body roll? I've never used them, but I could imgine them being significantly better. I think the engine strut bars would be very useful due to engine compartments being so susceptible to twisting..

I looked up H&R for sway bars for the year and model. they didn't have them listed.. They only had Wheel spacers and Springs listed, just like Eibach..

Yeah, some of the variants share the same sway bars, and while the H&R ones are thicker in diameter.
A good set of coilovers and tyre profiles (plus proper camber, toe) would help lots too.

oh yes, chassis bars will help in some extent.. more towards body twist when cornering. However good to check on your car when you get it.. there are already some chassis support bars fitted as original.

After that experence, I just want it to corner as flat as possible without going overboard, which is why I am looking just into thicker sway bars front/back and that should do it. The Sport package comes with the 18inch rims and I think they're a little wider than the 17's, if I'm not mistaken. I definitely will do more research on the chassis bars before I purchase, but the information is much appreciated…. I have other friends that might be interested in those…
I'm still trying to find the right car as I'm looking at both 2017 and 2018 C300's and there's not too many Sport versions with the Bermester stereo that are even available. not many 4matics with the right options either to choose from.. I'm finding a lot of AMG's on the market, but they are jacking up the price of them so they are out of my current budget..
