Eibach rear sway bar...

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.
edit: dsl ftw!??? haha

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.
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 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.
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.
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

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.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.

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.
