Question Attention Eibach Sway-Bar Owners!

Greetings!

Now that more than a few of you have had these on your C230k coupes for a few days/weeks, can you please comment on the following:

1) Ride harshness
Have you noticed any increase in ride harshness since installing the sway bars? If so, do you have any other modified suspension components (springs, shocks, etc)?

2) Cornering
No doubt it's a huge improvement over stock. But please compare if you've driven the AMG or Evosport bars. Any problems with wheel-lifting in hard corners?

Thanks in advance!

Hey, Bender Rodriguez Bender!

Young and I should be able to answer your questions tomorrow - I'll be putting on my Eibachs, and he'll be doing the decidedly less manly AMG ones. Full report will follow.

Just got it done yesterday by KWiK. I like it so far. No more of that floating and wobbling. Feels much sportier now. KWiK also did an excellent job. Very careful with his work.

Btw, I don't yet have custom wheels nor springs. Everything stock except the Eibachs. Turning corners is fun again, although with the cheap stock tires, the car still skids if you push it too hard. Understeer is also gone. Feels more responsive now. Better than the AMG that I test drove, I'd say.

Things to watch out for:

- If you have the projector-based xenons you'll have to re-level them. It look me 9 complete turns UP to get it corrected.
- Then there's the U bracket that attaches the xenon auto-leveling sensor to the front sway bar. Seems Eibach didn't include one. The original one in my MB was too small so it wouldn't fit in the thicker bar, so now I'm just using plastic ties on it, until I find a larger U bracket. Went to the dealer today to see if the AMGs come with thicker U brackets that I can use. Unfortunately though, they couldn't locate that part in their system.

All in all I love it. Was gonna get the AMG ones for $180, but decided to go $345 to get the sportier Eibachs.

KWiK I owe you some ice-cold drinks.

Btw, here's a picture of the U bracket for the xenon sensor (acutally it's only like 1 inch wide, so the pic might be too big or too small depending on your monitor size/resolution). Does anyone know what the part number for this is?

What does a thicker sway bar have to do with the aiming of the lights? A sway bar should not change the height of the car, right?

the xenon light have auto-levelers. the front auto-leveler arm is attached to the front sway bar. as the load in your car changes, the difference in position between the front and rear auto-leverer sensor is detected and the projector is adjusted to give the correct beam hieight. With the larger bar, the are is pulled down a few mm so the system detects a difference and tilts the projector. What oogle did by turning the adjustment screw is counter act the difference that the auto-level system is sensing.

Okay, I think i get it now. But does the sway bar really move that much depending on the load? I guess it measures small differences since you said it was a small mm difference in the bar size. This seems to have made a huge difference in the lights, since it sounds like he had to make a pretty big adjustment to the lights.

I installed the the Eibach sways a few days ago. They make the car VERY flat. I really like these bars. I would suggest putting the front bars on the stiffest setting, because of the size of the rear bar.

1) Ride harshness
Have you noticed any increase in ride harshness since installing the sway bars? If so, do you have any other modified suspension components (springs, shocks, etc)?

sways don't determine ride harshness, but yes, I also have Carlsson coilovers.

2) Cornering
No doubt it's a huge improvement over stock. But please compare if you've driven the AMG or Evosport bars. Any problems with wheel-lifting in hard corners?

Yes, on a steep driveway entrance I sometimes lift the inside rear wheel, but so what. When I'm taking hard corners on the road this doesn't happen. I really like these bars. I have not driven a car with Evosport bars, but I have driven a couple C32. Based on that, I chose the Eibach bars. A C32 isn't nearly as flat as my C230c or oggle's C320s with the Eibach sways.


Thanks in advance!

At first one would think that 9 turn is quite a bit, but must not be too much because 9+ turns are available on the adjustment screw.


oggle, or anyone else willing to come by my place that has a 2003 C with projector xenons. I would like to get another look at the auto-leveler sensor arm to see if the arm length can be adjusted instead of the zero knob in the housing.

Will I have problems with the auto-leveling of my Bi-xenon if I install Eibach anti-roll bars on my "soon to be part of the family" C320 Coupe?

If the auto level sensor is in the same location then yes, you will have this issue with any sway bar that is the same size as the Eibach. My guess is that it will be in the same location. This is not really a big deal because the adjustments are available. I also think that with another look, one will find an adjustment on the sensor arm also.

Self Leveling Sensor

Kwik,
Best way is to gross adjust via the sensor position relative to the new sway bar, then use the lamp adjustment screw to fine adjust it.

{you can also use the lamp top mounting bolt to make moderate changes to the lamp setpoint as well}

9 adjustment turns means you are "way" off on the bar position for the sensor.

You mean there's an adjustment on the sensor arm that hooks on to the sway bar? Or do you mean slide the sensor around the sway bar?

back to the topic

The Eibach bars are fantastic! At least a 50% reduction of roll over the AMGs and 85% over stock. I've only 3 wheeled going into steep driveways from a right hand turn going very slowly. No big deal. On the twisties they make a whole new car! Enjoy!

So is the sensor arm adjustable or does the arm come off the sensor and get repositioned?

If someone has pictures of this, please post.
