View Full Version : Viagra for your suspension: Eurocode swaybar and endlink review

It was pretty warm out this past weekend so I decided to install my eurocode sway bars and end links. Plus it got me out of putting away the Christmas decorations! I did not buy the AK, so this should serve as a good review for those considering going without the entire package. BTW, the quality of the endlinks made me want to hang them in my living room. Seriously beautiful.
I have a 2013 S4 without ADS, with sports diff. Stock suspension prior to this and with about 26k mi. Quite honestly, I wasn’t overly happy with the suspension in this car. Sure the ride was pretty comfy, but my god was the body roll unbelievable. I had a B7 A4 with the s-line suspension previously and it had nowhere near as much body roll. With the sports diff it almost made it worse too. I can’t really describe the feeling but it wasn’t confidence-inspiring and there was just a general lack of cohesiveness between the powertrain and suspension.
The install went ok following the instructions. The front was fairly straightforward and I used ramps, but I think investing in a ratcheting wrench set may be a good idea for this job. Like everyone says the rear is kind of a bitch. I found it easiest to: crack open a beer, put on some old school metallica, jack the car up under both rears, unbolt the two rear exhaust hangars, unbolt the sway bar bushings, remove the rear wheels, unbolt the sway bar from the end links, unbolt end links, pull the bar out via the wheel well (this was easier than I thought it would be but you still need to finagle it), sit down and crack another beer, tell yourself how much you are saving in labor costs and that this makes you more of a man, install new end links, put new bar in the same way the other one came out, bolt in new sway bars into bushings, put the wheels back on, lower the car, drive rear up on ramps, bolt up sway bars to the end links (this sucked due to lack of room – buy a racheting wrench) and put exhaust hangars back on (duh).
After driving this car for several days now, I’d say that the car seemed to stiffen up with regard to body roll about 60-70% (assuming 0% is stock and 100% is none/VERY minimal body roll). It’s really how the S4 should have come from the factory IMO. I have a round-about on my way to work and have generally gotten a good feel for the S4’s suspension characteristics, when other cars are not present of course. I found that with the upgraded swaybars, when you push it past 7/10 the roll becomes apparent/intrusive. Mind you, I am on stock non-ADS springs and dampers.
So the question becomes is it worth it? That is always an individual choice but I would recommend them if you find the body roll to be an issue. You will see real world gains and the quality is great. The only downside is spending money, but hey you got to pay to play and these are cheaper than the others. Ride quality really wasn’t affected from what I can tell. In fact the car seems to communicate the road a little better.
I just ordered a set of coilovers, so I will update this in the future to see how much better it gets.

Cool, I just had mine installed last Fri, and sorted out today. My 2010 car has the ADS and sports diff.

Love the way it drives in Comfort, but with much less roll.

The installers used the original nuts and bolts last Friday, which resulted in a knocking sound from the left rear.

Went back today after confirming that they had the new nuts and bolts (which I had originally asked them to do, but they forgot), and found out that the particular bolt had elongated, allowing the bar to come into contact with the lower suspension link.

All good now, and drives real nice.

coilovers and AK in addition will make a huge difference. The car has pretty phenomenal handling now in my opinion.

On my 2012 S4 wo/sport dif, I did the bars, links and AK. It certainly improved the feel and reduced roll for 90% of my driving. If I push it past 8/10ths I can feel the lack of the sport diff as the car pushes and doesn't rotate as well. Its a great upgrade for most of my driving and really like the improvement.

Did the coilovers or AK make the most difference? I just can't justify spending over $400 for the AK, ie. a brace. I know it is well made and they have done R&D for it, but still. It just seems to me more of a icing-on-the-cake upgrade. I could be all wrong though.

I had everything installed at the same time so I can't tell you.

Once I take my car in for work I will be throwing the coilovers back on and sway bars. I plan on getting the AK at that point too. I want to do it in stages though so I can actually feel whats helping with what.

Thanks for the review, I really appreciate it!

I wanted to ask, I am trying to be frugal and upgrade the suspension in stages since I just installed a BBK and bought a set of track wheels/tires. I was thinking to do front/rear endlinks first given how weak the factory endlinks appear. Do ya'll think endlinks alone would make a difference or should I wait and do them with the sways later?

Also, I am planning to do the work myself, can I install just the endlinks w/o removing the sways? This appears to be a really easy job if that is the case.

The AK really is absolutely worth it, I put it on my A4 (sport suspension with eurocode sways n endlinks) and it made turn in so much sharper it blew my mind. The rigidity it adds is a must have for an S4 with the added weight of the 3.0L.

You can do the endlinks without swaybars. With that said, I don't think you will see much benefit. I would either spend the money on swaybars or the AK first.

Install the sways and endlinks first, and drive it a bit. Then install the AK, and drive it, and post your opinions.

I did this.

The endlink and sways did help reduce body roll significantly but there is still some minor body roll. In addition, you can still feel the lack of the steering when taking a sharp turn. So once I got the Alu Kreuz installed with the sways/endlinks, the steering is precise, there is more control during cornering, especially initial turn in.

Overall, these mods will keep the car planted and reduce body roll. I believe a good set of coil overs will make day and night difference with these mods.

Thanks for the insight. I may just do everything at once now. Full Eurocode + coilovers. What coilovers did you decide on?

So.... Just got the front and rear sway's installed. Total time was 3 hrs start to finish and that included probably a half hour of fussing with jack positioning.

A couple of key points.

1) 5/8 wrench is virtually same as 16mm. Much easier to find a ratcheting box end. This should be included in kit....lol... Needed. in my opinion don't start until you have it.
2) Rear sway is not hard at all. Jack car up, support the car with jack stands, let the wheels hang. Helps with clearance issues. Drop exhaust down using 13MM ratchet. don't waste time taking the rubber off, just take the nuts off. Once you look at it, very self explanatory. You will need to pull the exhaust down. It has some pretty significant play. Take the endlinks off, Will help with getting bar out. You may have to use a Jack under a tire to help align the endlinks. Go slow, or you will strip the aluminum. Going crazy with an air gun or hand held impact might not be a good idea.
3) Front is super easy, just make sure to ensure the lengths of the endlinks match the ones that come off car. It helps if the front is actually loaded, meaning tires on the ground or ramps.

If you do a little research, and have some tools, this job is a 2 on a scale of 1-10...


How does it drive....

Much better, very flat, not harsh. Really should be the way the car comes when you buy it. It does change the composure to a little more oversteer tendency. I drove out in the wet, and I could easily induce the rear to step out on a corner. I left traction control on. Want to play with it a little more before I switch that off. I have the sport diff. I am waiting for the AK, so this test is without it. If the AK wasn't available I would be totally happy with the way it is right now. I suspect like others, the AK will tighten it up just a tad more, and hopefully help with turn in, but as I said, if I had exactly this. I would be fine. Great investment.

are you planning on installing coilovers?

SoloWerks. My buddy has them on his A3 and likes them. Also could not beat the holiday pricing. I'll put them on when it gets a little warmer.

Nice write-up! I have the Bilstein PSS10's on my S4 and have been considering the sway bars and AK. The sway bars are on sale right now, and with all the positive feedback I've heard from others and yourself, I might be pulling the trigger soon!

Thanks for the review!
