Hey All,

So I'm getting sway bars for my car and want to know why the Eibach sways are not listed for the C32. I just want the Eibach rear and the H&R front.

This seems to be the best combo from the research I've done.

Will the Eibach sways work for the C32? It list them only as the W203 Coupe and Wagon fitment.

I did a little searching and found that W203's share the same rear so will it work?

Also, if any one has some sways for sale let me know. I can trade my stockers with cash on top or just buy outright.

Thanks!

I have the Eibach sways installed. They were a straight forward swap. The part number listed for the w203 coupe are what I have.

You will need to drill carefully the front bar holes to 12mm. If you get the H&R front, get the regular w203 one and drill it, you'll save $ compared to the one listed for the C32.

AMG3.2

Oh really? I thought so.

I've read to get the H&R front and the Eibach rear. Is it advisable to switch brands? Or should I just stay with the H&R kit?

Thanks for the advice btw!

The H&R front with Eibach rear gives you the thickest bar combination readily available.

Your preference really depends on your goal. A thicker front bar will generally increase under steer as will a thinner rear bar. Since I track my car, I went with the Eibach combo as it gives me the best setup to reduce lean and understeer at the same time.

I started out with the H&R rear with stock front, then added the Eibach front, then changed to the Eibach rear from the H&R.

What ever you choose, they are both quality products.

Do you still have your old H&R rear?

03MBC32

Sorry, I no longer have the H&R rear bar.

AMG3.2

Alright, I'll take your advice and grab H&R front and the Eibach rear.

Thanks for you help.

Mixing brand makes no difference on swaybars. The spec goes by the thickness of the bar.

Eibach is the best setup imo.

AMG3.2

Thanks for the info. Eibach does not make that kit anymore so I'm going with the full H&R kit. I think it's a good choice.

MRAMG1

My only concern with the HR kit is that with that HUGE front bar, and staggered tires, you MAY have an understeer condition on your hands. I would certainly like to see it, with UN STAGGERED tires all the way around

03MBC32

The front and rear bars should still be available separately. That's how I had to get mine.

AMG3.2

Yeah they are. I ordered mine today from a local shop. I should have them by Wednesday or Thursday.

AMG3.2

Alright guys, I just got my sway bars on today. DAMN! They literally have transformed the car... The steering even feels heavier and the whole car just gives you a difference cornering confidence that was not present before. The whole car feels much more stable during the turn and exit.

I just can't wait to get Michelin Super Sports and a good alignment!

My Dunlop DZ101's are lasting too long. The front that is lol

Anyways, quick question. When driving I am getting a random knock that comes from the rear? It is annoying and I want it gone!

Is it an installation problem?

Do the bushings have to break in or become more malleable?

More grease for the bushings?

Any help would be great!

03MBC32

I had to trim the cover on the lower control arm for my installation. The bushings shouldn't need breaking in. Did you replace the end links? Highly recommended as the thicker sways will put more stress on them. There was a post a while back to install a washer on the the rear end links to prevent the bushing from piping out. This may be your source of the knock.

AMG3.2

I didn't have to trim anything. I didn't replace the end links either? Where should I get adjustable ones if I do get them. I looked online and HP autoworks had them for $160 for just the front ones.

Do the rears need them as well. And I'm trying to find the sway bar washer thread but I haven't been able to find it.

Thanks for your help

Although the links may not be the source of your noise, they're often irreparably worn.

You the man my friend

Was about to jump in, but you beat me to the punch

AMG3.2

Alright, I just took the bolt out and I'm going to go to OSH and get the washer. It's weird though. I never have the knock noise before the new sway bar. Any other suggestions?

Zeppelin

If there are multiple holes in the rear bar you might try holes further in from the end. The outer holes might make the endlink hit the control arm.

AMG3.2

Alright, well I did the washer mod to the rear endlink to prevent the bushing from slipping out.

For some reason I am getting more of a creak now when driving on un-smooth surfaces. My friend told me to grease the bushings, as the shop might not have done a good enough job at doing so.

Question: What are the torque specs or the sway bar bushings?

I'd really like to get everything dialed in the right way and keep the sound to a minimum. I'm all for a performance car, but not one that creaks and rattles during everyday driving.

03MBC32

Spec for the rear bushing bracket bolt is 30 Nm. Rear end link 40Nm. Front spec is 40 Nm and 60 NM respectively.

For the rear creak, as suggested earlier, replace the end links.

AMG3.2

Thanks a lot! You've been a real help.

So I went up a driveway today, angles of course to prevent scratching my carbon lip, and my rear tire actually came off the ground!!! I adjusted the sway bar to the softest setting in the rear! This is nuts. I don't want to say that the sway bars suck, but if I hit a corner hard enough is the inside tire going to lift?

This can be right, as others have the Eibach rear which is even stiffer?

I'm thinking its my OEM shock/ H&R springs combo not pushing the rear wheel down hard enough...

Any insight?

MRAMG1

Any time you go with a larger rear bar, you do indeed risk it lifting the inside wheel. I had this happen to my 91 stang, when I had Eibach make me a customer rear bar. It really played hell on my Auborn, which I blew out in one day out at Nelson Ledges.

Not really a fix here, other than what was explained above, aka going to its softest setting.

Zeppelin

Anytime you use a thicker swaybar to tune oversteer or understeer you will add more lift to the inside tire. You have to way this lift which could mean less traction out of the corner against increased cornering speeds.

I would not worry about it lifting the inside tire off the ground as in normal driving on the streets and on the track you will not encounter driveways.

If you like the stiffest setting just leave it there. My rear bar is stiffer than the Eibach and I could care less about the inside wheel lifting.

Only way to fix this would be to use stiffer rear springs rather than a stiffer rear bar but then you have a car that rides real harsh and would be unbearable on the street.
