Can someone please tell me:

1. Are Sportline swaybars the same ass 500E swaybars?

2. Are Sedan and Coupe swaybars the same?

3. Will adding Sportline swaybars stiffen the ride?

4. Can these be bought new from the dealer, or is second hand the only way?

Thanks for any help

No since there was no V8 'sportline'. They are different. The 500E is the thickest one.

I noticed a difference when I upgraded from the standard 300E bar to the Sportline/Wagon swaybar.

You can buy them from the dealer although it would be better if you could find a local junkyard with a W124 wagon since they use them.

So all S124 comes with sportline swaybars as standard?

And the difference you felt, was it in handling, stability, ride comfort?
Can you please elaborate

I noticed a big difference changing from wagon/sportline to 500E. This is after I replaced my lcas, H&R springs, and Bilstein Sports which weren't as noticeable. It's flatter and controllable in turns. I have yet to install the 500E rear bar but haven't noticed much oversteer.

I noticed a bit less body roll cornering. Can't say I noticed much else. Since I got it from the junkyard for $20...it was worth it for sure. New Bushings cost me $25 though.

How about ride, did it deteriorate?

pifcat2, with cars, the opposite side of the thicker swaybar gets more grip. So a front swaybar without a rear one would cause understeer and vice versa

Increased roll stiffness at the front axle increases understeer, not oversteer. Install that stiffer 500E rear bar to decrease your understeer. Mark

I always get those terms mixed! My point is, it rode much flatter. It was emphasized because I had no bumpers on my struts and would hear rubbing on fast corners until I installed the bar.

Installing the rear bar is more involved since the suspension bushings should be replaced as well. I don't have the tools yet and it isn't high on the to-do list...
