new 09 c300 4matic - did some modding
the car is white/black. 28k miles. fully loaded - navi, h/k, roof, bi-xenon, etc.
i did the following:
19" amg replica wheels
red painted calipers
amg rear spoiler
amg rear diffuser
quad tip conversion
black sport grille
32% tint all around
led eyebrows to match bi-xenons
philips diamond fogs to match bi-xenons
clear side markers
chrome bulbs that blink amber (turn signals and side markers)
removed chrome door molding
removed rear badges
magnaflow x-pipe
10" jl w3 + 250/1 jl amp
interior lighting kit
what do you guys think? before anyone says it - i'm not lowering it!

going to do an x-pipe and add a powered sub next week then i'm probably done.

AMG style steering wheel (can be the real thing which is 1" smaller or this lookalike which has the thick rim and contours, but saves $$ by being the OE diameter and therefore, can reuse the same air bag)

Eibach antisway bars - huge improvement in steering response and handling and has NO effect on ride height. I also won't lower my car, but wanted something much more responsive...this did it very well!
i just installed the x-pipe. it sounds nice. a jl 10" w3 running on a jl 300/1 amp is being installed on tuesday. i'm really excited for that. the c300 is my 6th car and i've never had a sub before. it's going to really compliment the harman kardon system.
i might do the anti-sway bars after that. i'm very happy with the car right now. i've only had it for 30 days, but that's one of the nice things about being 27 years old and making good money. when i was in high school/college it would take weeks/months to save enough money for a decent mod or two.

If you are really happy with the currrent set-up, wait a bit before going with bars, as they do reduce the "independence" of your very good German designed independent suspension. If you frequent rough roads, another reason to stay "as designed" with your suspension.

The upgraded bars don't change the engineering design philosophy of the suspension...they just move the line a bit toward the stiffer side. MB chose a calibration which they felt would satisfy a wide range of customers. If the OP, like me, is more toward the chassis performance side, we violate no basic principles by nudging the cal a bit tighter. Eibach did an excellent job in product development to balance improved performance with comfort. Our roads in Michigan are not regaled for being billiard table smooth, yet the car is perfectly comfortable here, keeping in mind my butt calibration perceives the Luxury model as unacceptably floaty.
Here's another test...if you got a C because you couldn't afford an E which you actually like better, leave the chassis alone. But, if you like almost everything about your C, but have a corner of your mind where you wish it felt more like a 3 series, upgraded anti sway bars are probably right for you...although it won't get you all the way there...but the steering response alone made it worthwhile......in my "myopic" opinion!

Sorry if myopic most often has another meaning.
negligible ?? Just for example purposes, some people have nice houses off of long, poorly kept rough roads, or live where the winters are rough: ie Philadelphia where pot holes are hidden by muddy water that overflows the hole, and frost heaves are severe (vs a Denver winter with good winter streets). In these conditions, the single wheel rate, which is much stiffer due to the big bars, will provide a much rougher ride.
1) By putting on bars only, you change MB suspension design philosophy.
2) The OP did a lot of Mods, and none were for chassis performance. So your "if" is a real stretch, with nothing to support it.
3) Again, you do voilate MB's suspension calibration.
MB engineers designed the suspenstion as a total package of bars, springs, and shocks (and also bushing durometer and tire type/stiffness). All of these variables are changed as you step up from the Lux model to the Sport model to the C63. OEM Sway bar diameters are calculated to 2 decimal places. Any time you change on of the three main suspension variables, with no proportional change in the other 2 variables, you have violated the MB design philosophy.
That said, I have put sway bar(s) on 90% of the cars I have owned, but they were not suspensions like the C300. In the case of my 83 Classic Saab 900T, it had no bars, so I added the bars (Saab Kit) that came on the next year's model. I donated my instructions from the saab kit to the Saabnet forum:

No, you have the correct meaning. I was trying to offer you a friendly way to gracefully back away from your tendency to insult, in this case a totally unsolicited reference to "myopic". I was trying to give you credit for having a more pleasant meaning intended, but apparently you do mean to invoke the insult as defined.
Interesting we have the same fun with cloverleafs. I actually tuned my Rx7's Eibach bars with race tires on, ~3am, on a big cloverleaf where you could stay in it non-stop with left and right corners.

Yes, there are widely varying conditions across the country and equally varying perceptions of ride comfort versus handling. I was making the point that on the relatively poor roads of Michigan, the ride comfort is quite fine. I am sure we can find a place where even the Luxury model cannot product good ride comfort. The OP has to decide whether his road conditions allow for even the slightest stiffening, whether from upgraded anti sway bars or something else, such as 18" wheels (or larger), for example.
100% disagree. Companies like Eibach and Racing Beat make an effort to provide suspension kits, where spring and bar rates are kept in balance as the rates are increased. Ideally, some shock upgrade would be recomended.

Perhaps our differing visions result from your expertise in modifying cars once built, while mine comes from being inside a major auto manufacturer for a couple of decades. It is quite clear to me from having been in the meetings and on the pre-production road trips that many dynamic objectives are calibrated for the average target customer. MB understands that some will buy the C Class Sport for looks, some for status, and others for different reasons. Not all (or even many) seek significant handling improvement at a negligible ride quality trade-off. As such, they aim for the middle two quartiles of the distribution for preference, which makes perfect business sense. However, this in no way invalidates the ability for someone who is outside the average to move the needle a bit.
Ultimately, your warnings are speculative as it seems you have not lived with a C300 with Eibach anti sway bars, and I have for a couple of years. The OP can decide as they wish...I have no stock in Eibach and am just trying to share a potentially enjoyable outcome for others.
Now who is being a jerk ?

As I said, this language is unacceptable and I regret that you cause me to have to invoke Moderator responsibilities rather than just discuss the substance of the issue as a fellow forum member. In my final comment, I was merely using self-directed sarcasm about your original insult...but, you need to find a way to resist having to call someone a name. Perhaps write your otherwise interesting and informative posts, and then delete the last sentence before posting? I hope we can all move on now with a more positive attitude.
