Negro - I would say no. Eibach's website doesn't show there being any sway bar options for your car. There must be a reason, though I'm fairly surprised that there would be a redesign of the suspension or undercarriage mid-generation.

Thats what i would say. i mean H&R have their sway listed as 01-07 all w203, except for front where difference lies in link bolt diameter 10mm/12mm .... i think eibach mentioned above will fit, im just waiting on somebody that has an eibach rear sway to chime in . my plan is to go H&r 26mm front and eibach 22mm rear.

I have Eibach front and rear, but for the coupe...pretty sure it's different. Just call Eibach.

Yea, im pretty sure the rear suspesion in the w203 from 01-07 is exactly the same (on the sedan at least), but I have actually never seen the eibach bars sold seperately... The front and rear eibach bars are usually sold together, so id be a bit cautious about the link, but the best way to find out is to call and ask.

can you actually feel the difference in the thicker sways? Or is this more for theoretical improvement?

The difference is not theoretical, it's proven. Like night and day. Have you seen the factory rear sway bar? It's really weak...

If you've never done it, you will never know the night and day difference it makes in the corner. I was skeptical prior to installing them, but its SUCH a huge difference its hard to describe until you try it. I feel the difference in every turn i make and sadly every steep drive way i have to climb and potentially 3 wheel my way up...

edit: search for frank's posts (or maybe frank can post again) comparing all of the sway bar options (including stock) and their thicknesses / stiffness. The numbers alone are pretty impressive.

Ive got both and the quality of them seem equal. I have faith that both manufacturer's sway bars will last a very long time, but the bushings, like all bushings, are bound to wear down and will need replacing and regular lubrication to avoid creaky noises.

edit: dsl ftw!??? haha

It’ll fit.
Likely be somewhat closer to neutral during low speed transitions and sweepers on our understeering pig of a chassis.
Might be a wee bit tail happy exiting 75+ mph (closed course) corners for some, though, given enough thrust.

haha.
Mine did the ‘dog pissing on a fire hydrant’ routine every time traversing our wickedly off-camber driveway, even when stock.
It’s at the square of their [spring and bar] diameter more pronounced owing to its current configuration.

I am pretty certain all of the w203s including AMGs share 10mm holes on the rear sway bars for the end links, so all rear bars that fit any w203s should be interchangeable.

I am pretty sure all w203s sedans and coupes use the same front sway bars (except for the c55, which would need the clk55amg/w209 front bar). The front bars on c32s have 12mm holes for the bigger end links while the non amgs have 10mm holes for end links on the front.

For non AMGs: When purchasing front sway bars, make sure you get the 10mm NON AMG front sway bar otherwise you will need to modify your strut (unless you have KWs COs) and use 12mm AMG end links or C3 adjustable 12mm end links.

Note about the front sway bars: If you get an aftermarket front sway bar, you should upgrade the sway bar brackets if you are pre-sport suspension (i think before 05) to AMG brackets, otherwise your bar will make some funny noises because the bracket holds the bushings too tightly around your front sway bar.

Hopefully, this clears it all up.

Some non-AMG W203s are, in fact, equipped with 12mm front anti-roll bar links, particularly those such as the OP’s later renditions. It's easy enough to verify before ordering replacement or aftermarket hardware. No disrespect intended, TruTaing.

Seems MB saw fit to rightly empty their parts bins of their ‘good’ hardware as model line neared the end of its production run. Note H&R commands a slight premium for their 12mm-link bar. A quick pass with a #12 metric drill bit (.472 inch) makes the upcharge superfluous.

As correctly mentioned, there is a potential bushing mount issue of which to be aware when fitting an H&R front bar to our various chassis…

edit: previous post referred only to upgrading your rear anti-roll bar.
Make that end contribute its fair share to the cornering equation first.

so your saying replace the rear before replacing the front if you only replace one at a time?

Ok, so last night i finally got around to install my front H&R 26mm bar and rear Eibach 22mm bar. To clear all the misguiding information thats floating around all internet stores , listings and Eibach information. Rear EIBACH bar 22mm will fit 2006 C230 SportSedan, even though the listing only states combi and coupe 2002-2004! As far as the front H&R bar, there is a slight issue with the bushings, they arent excatly profiled to the funky looking bracket that MB created. I tried aligning it my best, but im still not completely satisfied , ill guess ill see how it performs in the long run.

Update: got a chance to run it on a freeway earlier today ....I must say , im almost in the BMW handling territory with this upgrade. The heavy pig sway is gone

None taken Im just glad we can get this info out there and clear it all up. Wish there was an official "EVERYTHING about w203 sway bars thread" or one post that has like 90% of the info.

Glad you're enjoying them. I think swaybars (and suspension in general) are one of those mods that you can feel everyday on every turn. Very satisfying in my book!

This is so true. My 2007 4matic has an AMG rear sway bar and what might be an AMG front bar as checked with my caliper (did anyone ever confirm if the front swaybars on the 4matic are the same as on the 2wd)

So I have the 22mm front bar, I'm thinking I should go with an Eibach rear bar, to help control my body roll. I can't change the front bar (not with out an engine hoist).

Can anyone comment on how the Eibach or any after market rear bar works with the AMG front? My body roll is a bit excessive at low speeds.
