    What are the best springs for lowering? Kw adjustable ones, ED, HR or 034 motors? Anyone have compared them?

    I love my KW HAS kit. Ride quality is amazing.

    How many mm did you lower the car? You where also able to obtain the stock front-rear balance?
    Did you had any chamber issues when you lowered the car?

    Thanks for the answers!

    I have ABT HAS, sourced from Mops

    Very compliant ride and a big improvement when paired w/ 034 RSB.

    I went with the ED springs and their rear bar. This car will never see the race track, will be driven in the Western NY snow all winter and I wanted a lowered stance I but didn't want to sacrifice too much of the ride quality. ED was the perfect choice for me - they've been on about a month and I am very happy. To me, it's what the car would have been like from the factory if there was a sport suspension option.

    I have the ED springs but the car seems unbalanced now because the front has dropped more than a rear.

    Between 034 and ED, which one has less harshness? which one has more drop?

    I'm having a hard time figuring that out just by looking at the pics, and the Specs don't really show the whole story (seems the ED drop more, but i've read some reviews saying the 034 is harsher which makes no sense)

    ED uses a linear design which is similar to stock and the spring rates are lower. 034 is a progressive spring with a higher overall spring rate (based on published rates).

    I have the ED springs and the rake looks OK to me on my car. I didn't want slammed - I wanted it lowered to remove the giant fender gap and I wanted it a bit stiffer. in the end, I don't notice any harness in my ride and Western NY roads suck. I also added the ED rear sway bar. The best way I can describe this set up is it looks and feels like what I would have expected if Audi offered a factory "sport suspension" option on the car. It is very civilized.

    I was in the same boat as you. Trying to decide between those two springs. The previous post stated that ED springs are linear that is correct while the 034 are progressives and have a slightly higher Spring rate.

    I opted for the 034 because I will track the car so the progressive is better for that. I think the drop looks great with both springs and are pretty much equal as far as looks go.

    I have not noticed any difference in ride comfort. The body lean in turns is greatly reduced as well as how far the car squats back under hard acceleration with the 034.

    I am super happy with my choice and people are constantly telling how good the car looks. But you have to get use to that with the S4, lol.

    It really depends what you are after, but for those who daily drive their car and wish to maintain OE ride quality with a manageable drop, our springs are a fantastic option. Using a linear spring design (like the stock springs), they pair very well with the stock dampers on both mag ride and non. With our springs, the car will be lowered for a more sporty appearance, while not forcing you to alter your driving habits (such as slowing down for dips, taking driveways at a steep angle, etc.).

    Combined with the rear sway bar upgrade, the car will be just as livable as stock, but much more capable both on twisty roads and track environments. A stiffer spring does not necessarily equate to a better track setup. If the chassis is easily upset over bumps and road imperfections, it will force you to go slower. By having a planted and predictable suspension, you will be much more confident exploring the limits of the car.

    Yes, this should give a good idea. This is a before and after, typically there is about 1/8" of setting after this.

    I have the ED springs on my car and just ordered the 034 motors, in a weeks time I will give my my opinion which one is the best. What I don't like about ED is that the front is kinda out of balance because the drop from the OEM in front is 4-5mm more than in the rear, 034 drop is same in the front and back and this should give a better balance to the car. Who is looking for the lowering springs for the S4 remember the ED where designed for the A4, 034 where specially designed for the S4.

    We maintain both a B9 A4 (non-sport) and B9 S4 with mag ride in our development fleet, to give us development and seat time with different suspension codes. Regarding any perceived change in balance related to fender height, bear in mind you are speaking of a difference of millimeters. With a motion ratio less than 1, the spring compressed height difference will be negligible with such a minute amount (not to mention you can find millimeters of fender height discrepancy simply from fender alignment, fuel level, etc.). Our springs are intended to maintain an even tire to fender gap, which is why we opted for the load heights that you currently see. We have tested with different heights before settling on the current variation, and the change in handling and chassis responsiveness (independent of spring rates) was imperceivable.

    I can tell you in a weeks time witch one is better, yours or 034 motors. I have owned lot of S and RS Audis and heavily tuned all my cars, specially the suspensions, so I know what I'm talking about...

    I'm very interested in your findings. I'm looking at both 034 and ED w/sway bars.

    Il give you my opinion next week when I have installed the 034 springs. I think sway bars are the same from both company's (ED and 034). I believe Eurocode has the best sway bars in the market from my S7 experience when I used the steal 034 rear bar against the hollow Eurocode bar, the hollow Eurocode bar was much stiffer and felt better.

    fwiw, I've never noticed any negative handling characteristics with the front being slightly lower than the rear, but I'm not going around a track trying to shave-off milliseconds from a lap time.

    Its not only about that, I think the ED have way too much body-roll also.

    I think the ED are spot on as to what they advertise... I nice lowering spring with a ride similar to stock. I am very happy with the look, handling and the ride quality.

    +1, I thought the stock adaptive suspension needed to be just a tad stiffer with a little less body roll than stock, and the ED springs + rear sway bar totally accomplished that. I love that I can still cruise over uneven surfaces the same way as well (which is basically every road in Seattle), the car doesn't track or follow every crack in the road in Dynamic and handles rough/off-road surfaces in Comfort just like it did when it was stock.

    A set of linear springs with a compressed spring rate near stock are never going to do much for body roll on any vehicle, but the thicker (and 125% stiffer) rear sway bar definitely will, and that was noticeable to me immediately under hard cornering, it was particularly pronounced on an S curve that I'd been on before/after.

    That's why I will try the 034, I think they are stiffer and have less roll.

    some springs lean more towards comfort trying to retain oem handling, others lean more towards performance handling. Seems like more performance oriented springs will be a better match for what you are looking for though.

    too bad they don't have super sport or race springs available for this platform yet, you might like those if the stiffer ride doesn't bother you, but a good set of adjustable coilovers set to the stiffer settings do the most for body roll in my experience, more than sway bars, it's crazy how flat a car with good coils stays in the corners.

    Yeah, kw coils make audi drive almost like a Porsche. I just don't see anything on the market for now, only for avant there is a expensive KW V3 version available.

    The 034 are much better if it comes down to handling and body-roll. You cant compare these springs to coils but they are better than ED ones.
    I would recommend also the 034 Engine strut bracket, it makes the steering more precise.

    034 Springs. Sorry I couldnít get same color comparison in the photos. It was a bit more cloudy the day I took the after pic. As you can see the ride height is subtly lower. Keep in mind the before pic is with factory sport package ride height. Handling is way better and car feels closer to the ground. I have an issue where at low speeds the spring coils are binding a bit when turning the wheel and a knock/popping sound is produced. At higher speeds itís completely inaudible. HS Tuning, here in Ohio, performed the install. They currently have a tech request open with 034 to see what gives with the popping. My tuner has a pic of the front springs while the car is on the ground and the top 4 coils touch. They said this is highly unusual and at the most 3 coils should touch. Other that all this I love the look, ride and handling of this set up. Rear sway bar is next.

    Anyone with H&R springs on that can weigh in? My B8's H&R springs seemed to close the gap just slightly more than the ED/034 do on the B9 so curious to see if the H&Rs are slightly lower in this platform.
