    Looking at Handling mod; Have a few questions regarding sway bar

    Guest-only advertisement. Register or Log In now!
    Since I'm a good boy, I searched before doing this thread but still have some question ;

    My car is a 2013 with 92 000 kms ( almost 60k miles). so it might developped some slack this and there lol.

    What I'm looking for : ( and feel free to add anything else down the line!)

    1) O34motorsport/eurocode tranny mount + both rear diff mount : install is simple. price is fair at 230$ for the 3 items and it seems to provide good result. I do get that little clunk downshifting in D when coming to a red light and read that these 3 items could/should resolve this issue.

    2) Sway bar : This where I need your input most ! Some people have reported that when installing both sway bar, the car became uncomfortable, more road noise, much stiffer ride. Some even said they switched back to OEM. Then, there's other who are saying only the rear need to be swapped. Then, others are saying if you don't swap the end-link (which cost as much as the sway bar itself) you won't see any difference. And then, I read those spherical bearing needs to be rebuild more often than they should.

    Like SO MANY different opinions that I don't know what to think about sway bar mods.. Sure I want to reduce bodyroll and be flatter while taking ''high speed highway exit'' and such, but if it's going to introduce new problem, IMO it's not worth it lol

    3) Suspension : At the moment, I wish to stay stock. I enjoy how ''smooth'' the car roll and how I can go over speed bump and pothole without having to worry about breaking my car or hitting my head on the roof lol. Sure I wouln't mind a slight drop of 1 inch to reduce the gap, but i prefer comfort lol :)

    4) CR-15 : heard that it stiffen the direction and for a good price, easy install. so why not ? Haven't considered the aLu-kreuz because of the very high price. maybe if i see one for sale used at bargain price, I will go for it, but at 420usd, I prefer to put my money on something else IMO.

    5) Braking : I was thinking about the 2-piece ECS oem-size rotor, along with SS hose and Hawk 5.0 Street pad. Anyone ran this setup ? is it worth it or better put this money toward a BBK ?

    6) Tires: On my skyline I ran both the sumitomo HTR Z3 ( same category as the super sport pilot but MUCH LESS pricey) and I'M leaning toward these one. However, I also ran the dunlop direzza star spec Z2 ( after trying the sumitomo and felt a good improvement in grip) However, my skyline was more race-tuned than the S4 so I don't think the improvement will be felt as much + direzza is pricer, wear quicker, less wet grip and more noise ( which sometimes made me paranoid thinking I was running on a flat lol)

    Am I missing something else ? Thanks for your input as I'm a bit lost at this.

    like you I wanted to improve handling, while greatly limiting adverse effects. I chose to replace both front and rear. why? I was not after just greater rear rotation but an overall flatter complete balanced package. yes a rear bar solo will also reduce overall roll, but my concern was roll alone and NOT the rear rotation. so I did both. I also did not want to rebuild the spherical endlinks, spend the money, but still wanted better than stock. I found MOOG made replacements fully metal with stiffer bushings, and much cheaper. I went this route and VERY happy. Overall I have an ever so slight increase in road noise, no increase on bumps. harshness didnt really change all that much. Now that I have had them on for a while I can't tell a difference from stock noise wise. The feel is amazing and exactly what I hoped for.

    I went with eurocodes, and while nice, I'd go with the 034s if I were to do it again due to the greasable bushings. One thing I ran into that I was kinda miffed about, unless you go to the spherical bushings you are NOT able to use the rear sway bar as an adjustable bar. you can not force a solid endlink (stock or MOOG style) to fit into the "softer" hole. I don't want it to be in that position, but it kinda irks me that I don't have the option.

    regarding the others:

    3 - look into U2Nelson's strut tower brace. between this and the swaybars I'm not sure I want to do anything else. was surprised how a cheap piece can make a huge difference. Search for him in audizine and see if he will ship to canada. I'm also considering the KW HAS (height adjustable springs) that are not that much firmer than stock but allow you to lower a bit.

    4 - crap. well, see 3. and after the sways and the CR-15 I ruled out the AK. get those two and then decide if you want it or not.

    5 - standard slotted will be better... but the 2 piece, wave design especially, look nice on top of performing well and being slightly lighter. I personally have had terrible luck with HAWK pads and refuse to use them anymore. I prefer Carbotech if you really want aggressive pads, EBC for slightly better than stock and even wearever is pretty good for stock replacement. that aside I'm also a fan of Brembo blanks and running stoptech pads as well. You can also consider the RS5 brakes. check ECStuning.com for a couple options to look at.

    6 - I'm going with PSS myself. I read a few articles and a nice head to head comparison that sold me on them. you can do what you want. but for the length they last and how they wreck everything else in combined predictability, wet, and dry handling there is currently nothing better. But if you dont want to spend the money then try something else.

    Keep in mind a bigger front sway bar will increase understeer, which is obviously not desirable.

    From what I've experienced on my car, here are the most beneficial options in order of effectiveness.

    Tires
    Alu Kreutz
    End Links
    Sway bars, I would just got with the rear.
    Springs

    I would not get the HTR tires. Tires are the key, regardless of how the car is setup. I would get PSS, AK, and end links in that order. Trust me, it will be night/day from stock.

    If you want to take it a step further add the rear sway. The end links by themselves, without the accompanying aftermarket bigger sways, will increase the stiffness of the stock sways by about 25%. They are very important. For example, if you simply install larger sways on the stock end links, you're essentially wasting your time because where it all meets on the stock bushing is plastic crap.

    I wouldn't cheap out on tires based on the S4 not being as "race tuned "as the Skyline, the benefits will be huge as tires have the most impact out of anything you will do.

    Only thing I can speak on is #3. I have bilstein coilovers and I actually think comfort is the same as stock if not slightly better. I'm by no means slammed, about 1" drop all around, but the handling was greatly improved over stock. Eliminated body roll, lift when accelerating and drop when braking and the steering fells tighter. Granted this is the most expensive suspension mod of the ones you mentioned. Just don't feel like you have to sacrifice comfort with coilovers. I can only speak for the bilsteins which are the more expensive coilovers for this car.

    I have the Eurocode front and rear bars, both set to the stiffer setting, and stock endlinks. Much better handling with minor degradation of ride comfort, no increase in noise. The stock endlinks hold-up fine...they are made of plastic, but they are not exactly silly-putty. My guess is that the solid endlinks (expensive and wear-out quickly) maybe slightly increase the initial response of the bars, but it is not a "25%" improvement versus the stock endlinks....maybe 5% better.

    I also have the top strut tower chasis reinforcement, a subtle improvement, I would say OK for the $125 spent. I have no added noise or decrease in ride comfort due to this.

    I doubt the Al Kruez improvement is worth the steep price....and honestly, the stock steel subframe, and the stock aluminum reinforcements (right above the steel subframe) that tie the inner pivot points of the two lower control arms together, look pretty stout to me.....I doubt the Al Kruez is really much of a rigidity improvement.

    I did the eurocode sway bars. If I was to do it again I'd get the 034 motorsport bars instead due to their greasable mounts with no real difference in the bars.

    Hello
    Suspension is a very individual thing. It depends completely on your own driving style, what your desired traits are, and how/where your car will be used.

    That being said, for most daily driver enthusiasts who may do a couple track days or autocrosses per year but who also place a high importance on comfort/daily driveability id recommend doing a front and rear swaybar setup from H&R.

    I like front and rear setups for a couple reasons. First, even on my track cars I have often gone with both because I like the added turn-in response it gives. The S4 is particularly weak in the spring/damper department and adding a bit of antisway has a big impact. I have actually found turn-in is improved so no concern about horrible oversteer. Second, i've done rear only setups many many times on different audi platforms including the B8 (a4) and it always felt much better to me after adding the front.

    I particularly like the H&R setup because it comes with teflon coated bushings that dont make noise and never need to be lubricated. Install and forget.

    As far as concerns about the ride becoming harsh with F and R swaybars, absolutely dont worry about this. Swaybars have very little impact on ride comfort. They are activated more so during turns (ie, side to side induced motion) and wont have much of a change in feel riding along the road.

    I would stay away from solid end links on a daily driver. They require maintenance and they can make noise. IMO they dont belong on a daily driver but thats up to you.

    With respect to drivetrain mounts, they can offer some really nice increased "feel" and responsiveness in the chassis/transmission but dont be shocked if there is a bit more NVH/vibration felt. Make sure you are ok with that.

    All good ! :) hahaha

    seems like 034motorsport are well-regarded in term of handling part. suck I missed the blackfriday party lol

    This might make you feel better about the inserts. Same thing but cheaper than 034

    ON my skyline, I had solid mount on everything except engine mount who were ''hardened rubber mount''. Tranny, subframe, rear diff all had Solid metal bushing/mount. So, I'm clearly OK with some NVH. it just that I chose the S4 over another ''more-race platform'' because I was looking for a good combination of sport and conform and so far I'm really happy and impress on how SMOOTH the car ride, but I've noticed 2 things that bugs me a bit : slight clunk on downshift from times to times ( which i think the 235$ 034 motorsport could fix) and the ''famous audi oversteer''. I had sway bar on the previous car and felt a nice improvement. Guess I have my mind pretty set, but feel free to keep the comment coming :)

    Hi there
    You will be good with tranmission mount fix. I see eurocode has better price on the item. (i m on eurcode tranmission mount)
    no longer has that "clunk" from 2-1 on DSG.

    For the ARB, you would wana change the Moog endlink first. the effect can be immediately felt with tighter steering response.

    And the aLu-kreuz thing, you would wana stregthen the OEM piece by welding some addiitional piece across. I did this way as not to have any OEM parts laying around the house. And it make the ride feel tighter.

    as people have said, suspension set up is a pretty personal thing. I'm one of the guys who did not care for the bigger sway bar "upgrade" i did not feel it improved the actual handling over stock for street driving (I have the sports dif) and the car lost a decent amount of its refined ride IMO. FYI, this is first car I have ever tried bigger bars on that I did not like what they did. To me, It felt like putting a straight jacket on the multilink suspension. I went with Koni shoocks front and rear instead with the stock springs, (on soft setting) and like the bump in car control and an even more refined ride.

    the DSG tune from EPL fixed all my shift clunking issues.

    OP, all those are good mods, but why? Are you just trying to hit on-ramps faster, or are you thinking about autocross and tracking the car? Most of those mods won't really be felt unless you're pushing the car hard. You can spend $10k on all the stuff you list, and for what?

    I've got everything you list and it's all great, but I track as much as possible. The Eurocode goodies, trans mount and the CR15 are all good cheap mods. After that you're in the break-out-another-thousand category.

    I feel you ! Hence why I was tempting by the 034's goodies mount, cr15 and sway bar most likely. after that its a big jump at 420$ for one reinforcement + than 1-1.5k for coilover :)

    To answer your question, I enjoy spirited driving ( i.e: little zig-zag, like to enter/exit an highway at higher speed than the normal person would) so I like '' sharp/flat/nobodyroll'' feeling. As of now, I barely tracked the skyline GTR. I doubt I will ever track the poweful family sedan :)

    By the way, thanks for passing on your knowledge. So far, I'm enjoying this forum a lot :)

    To answer your question, I enjoy spirited driving ( i.e: little zig-zag, like to enter/exit an highway at higher speed than the normal person would) so I like '' sharp/flat/nobodyroll'' feeling. As of now, I barely tracked the skyline GTR. I doubt I will ever track the poweful family sedan :)

My guess is that the solid endlinks (expensive and wear-out quickly) maybe slightly increase the initial response of the bars, but it is not a "25%" improvement versus the stock endlinks....maybe 5% better.

    I also have the top strut tower chasis reinforcement, a subtle improvement, I would say OK for the $125 spent. I have no added noise or decrease in ride comfort due to this.

    I doubt the Al Kruez improvement is worth the steep price....and honestly, the stock steel subframe, and the stock aluminum reinforcements (right above the steel subframe) that tie the inner pivot points of the two lower control arms together, look pretty stout to me.....I doubt the Al Kruez is really much of a rigidity improvement.
    So your opinions are based on just looking around and guessing, based on what?

    Research threads posted by EC, their endlinks increase the stiffness of the stock sways by 22% to be specific. This is according to the manufacturer, not my off the cuff guess or simple guesses like your post is full of.

    For proof, look at post #4 - http://www.audizine.com/forum/showth...Sways-Endlinks

    The stock end links are garbage, and bigger sways without them are not really doing anything. The reason why this is a fact is because of their poor materials used, not to mention the stock links also wear out within a few years, just like the better aftermarket ones, however the difference is that the stock endlinks are not designed to squeak when they fail so you would never hear it. Chances are very high your stock endlinks are completely shot, but you just don't know it.

    The AK absolutely increases chassis rigidity by a lot actually. The stock piece is basically hollow steel all welded together from 9 different points. How would you know it wouldn't increase rigidity either way unless you have direct experience with it or helped design it? Or you can tell by simply looking at the stock subframe design and components?

    This statement is a bit misleading. Most of the aftermarket swaybars out there are going to improve stiffness over the stock sways somewhere between 50% on the low settings and the smaller bars to 125% on the stiff settings or larger bars. Upgrading the sways and using stock links does make a difference. All you have do do is drive on a set of upgraded sways and this is immediately apparent.

    I dont think anyone is doubting the merits of solid end links. This isnt a new product. Theyve been around in racing for decades. The question is if the added 22% over already larger sways is really needed or going to be utilized on a street car more so than the drawbacks. Thats up to each person do decide.

    The post you linked to also stated "The stock endlinks are more likely to squeak than our USS." I like the EC folks and David but I disagree with that statement and I disagree with you that the stock links are so trashy and wear out quickly. They're not perfect, they're made for comfort and also for longevity (they are not made to need to be serviced/replaced at the 1 year mark). There are plenty of people (most really) who wont ever need to replace stock links in their 5 years of car ownership or whatever. And most will never get a peep out of the stock links as well. Anyone who knows solid links knows they require service and they will start to make noise eventually. This is pretty common knowledge.

    Again, I'n not disputing the merits of them. On my track car i'd pop them on and you wouldnt hear me complaining when they need to be serviced and start making noise. No big deal. I wouldnt say that you need to use them to get any benefit out of upgraded sways though. You dont.

    Hello,

    Personnaly, i have the following "chassis goodies":

    - H&R Front and Rear sway bars (front with hard setting)
    - H&R Front 10 mm and Rear 12 mm spacers
    - KW HAS Springs kit with a moderate drop
    - CR-15 Strut brace (verry cool, sharper steering )

    - Michelin PSS Tires

    This moderate pack of mods is verry comfortable and gives a nice behavior on street and occasionnal track days.
    The body roll is verry limited, the cornering is verry sharp, but comfort is OK.

    Thats a really nice setup Mat. I'd probably do your exact setup and add the eurocode AK if I were modding my S4 as well.

    almost the same path I have made. though I'm planning new wheels instead of spacers and went with the Ecode sways. if you have not done them, consider adding the MOOG endlinks if you want something a bit more robust without going spherical. cheap too. for a daily driven car I can't fathom needing more. I ruined my old mustang going too far, and wont do that again.

    The way I "reckon it" : if the car rolls lets say 2 inches ( 2 inches up on one side and and 2 inches down on the opposite side) that is a total of 4 inches of sway-bar bar movement (at the ends of the arms), and lets say the stock endlink rubber bushings compress 50%, or about an 1/8 inch on one, and another 1/8 inch on the other (the total bushing rubber thickness is about 1/4 inch), then the loss of roll reduction is 1/4 inch divided by 4 inches = 6.25%....not a big deal, and certainly not "22%".......This also assumes that the plastic body of the stock endlink does not compress or stretch much....which I think if it did, it would soon snap in half....

    For reference, 2 inches up, and 2 inches down (of vertical displacement at the sway-bar arm ends) is about 3.8 degrees of chassis roll angle, which is a significant roll amount.

    any way to get the eurocode goodies without paying 30$ for shipping on a 165$ item ?

    EC mount kit is 165 while the 034motorsport is 225$, but when you add the uber expensive 30$ shipping cost , the difference is much less lol

    What does 034 charge for shipping? If 034 is offering free shipping you're still ahead by purchasing the ecode parts, seems you'd rather not pay shipping or expect it to be subsidized. Why should ecode eat the cost for shipping to everyone? I ship things from California to Manitoba all the time and I pay quite a bit to ship things to Canada - this doesn't include the additional import duties that need to be paid. Why don't you have it shipped to a PO box on the other side of the border and drive over and pick it up? 30 doesn't seem unreasonable to me at all.

    In order of enjoyment.
    EC Shortshifter
    EC Alu Kreuz
    Vogtland Coilovers
    EC Swaybars
    Hankook V12

    If you have doubts on the Alu Kreuz's worth ...don't. It's easily one of the best mods and combined with the Shortshifter it transforms manual shifting.

    Thanks for all the comments.

    I'm suprise the mount aren,t talked more.. guess the ALU is a better mod then !

    With that said,

    I'm leaning on sway bar + moog link + CR-15 brace to start with. When summers comes, I will look into other stuff.

    Not sure if I should be making another thread, but I'm curious what's everyone opinion on Stoptech sport slotted rotor Vs ECS one?
