So i upgraded my bars last night and the parts numbers I used were:
front
A-203-323-44-65
22mm my stock was 20mm
Rear
A-203-326-15-65
16mm my stock was 13
I drove the car this morning and all I can say is that this is a really good upgrade and I am glad I completed one more project.
next on the list
1-vinyl wrap the top next week when Don gets to the bay area
2-tint windows 30% all around.

the part numbers listed are the new sway bars you got? My front stock is 22mm and the rear is 13mm. So looking to just replace the rear ones. Did you have to switch out any parts? If yes, what are they and part numbers associated with them would be much appreciated
Thanks!

Bushings: 203-326-12-81 x2

No drilling, straight bolt on and it's possible your
existing endlinks are 12mm. You should measure them.
In 05 the facelift included AMG bars and endlinks.
Measure to be certain.

Well, I just was going to eat my words, since I could only find where the
rear bar was upgraded and ha, it says 14mm and nothing about the FRONT (correction) bar.
I forget what my AMG rear bar was, but the stock one I looked like spagetti.
Some interesting reading on the differences from 2004.5 -2005 "facelift"

Go straight to the 19mm H&R and skip the AMG bar, it will still UNDERSTEER (EDIT) horribly.
Been there, done that, sold that to another forum member, who in turn sold me a whole set of C7
wheels for $50. Well one was cracked. But 2 had good tires.
Use your 'gift' certificates for other stuff.
The coupe is asssss heavy and mercedes was too lazy to
recalibrate the suspension, instead choosing to adopt a one size fits all,
sedan coupe, wagon. BS.
On top of the cache of parts I've accumulated I'm also getting my brake fluid flushed
for 115-100= $15 + tax.

Wait, it over-steers with C32 rear sways (16mm) and not H&R (19mm)? I was under the impression that with stiffer the bar, you go from less under-steer to neutral balance and eventually to over-steer. So wouldn't the H&M (19mm) make the over-steer even worse?

Correction, I meant understeer horribly.
Yeah, turn the wheel and plow head on into a ditch.
Went from 16 to 19mm rear bar, and boom the front was digging into the
corners.
