    Thinking of fitting one of these kits on my 08 3.0 TDI Avant. It's an SE so has a bit of that 4x4 look. This kit is supposed to be 30mm front and rear which I think will be just fine for me. Used to have 30mm Eibach springs on my Passat and used to ride really well.
    Has anybody pictures of their car with one of these kits on ?

    Have you got the 'standard' suspension?

    Yes it's an SE with the 1BA option code for standard suspension.
    NOt the best picture to see but this is what is currently looks like.

    Yeah quite a bit of arch gap, I would go for it. I've heard good things about these kits not affecting ride etc

    Personally I tend to avoid just springs as they can ruin your shocks and don't give the best ride, I would go for coilovers my self infact I'm having some fitted next Thursday to my B8 saloon.

    After surfing around the net and finding some pictures I have ordered a set of Eibach Pro springs.
    Found them a bit cheaper here


    Eibach Tieferlegungsfedern AUDI A4 B8 Avant 2 30/30mm | eBay

    Made an offer of 145.4 euros so in the end with postage it works out at £141 delivered. About £40 cheaper than the UK.
    Will put that towards the intercooler :) .

    The reason I don't like springs is your shocks are designed at that height for a reason this being they give a bit of travel before starting to damp and you go and lower it 30mm you are riding round with your shocks already damping the further they go down the stiffer they get that's why you get a bumpy ride with just springs fitted where as coilovers were designed to have the shocks go that low.

    ... Why not get springs and shocks then? Good springs and shocks will work out cheaper than decent coilovers.

    Yeah if you don't want to spend a lot then get springs and shocks that's ok I agree do that, but I would rather spend a bit more and get coilovers but that's just my personnel preference. You don't have to spend a fortune on coilovers to get good ones AP coilovers are plenty good enough and they are only £5.15 I've had them on a few cars and really rate them I've got two friends with R32 golfs one has AP that cost £500 the other has Eibach that cost £1000 and I can't tell the differance only the Eibach go a bit lower.

    I think you will find that the amount of movement a shock travels before it starts damping is the same regardless of it's position in the tube.

    HowStuffWorks "Dampers: Shocks"

    How does the shock absorber in a coil over set up differ to ones on a standard car. A coil over is designed to work over a large range of adjustment so the starting point of the shock will vary depending on the installation height.
    The reason people usually get a bumpy ride fitting lowering springs especially 45-50mm springs is the car is usually then sitting not far off the supplementary spring, some people see this as a bump stop. It does more than that as it is available in different lengths depending on the suspension drop of the car. In the case of the B8 A4 81, 72 And 66mm.
    The supplementary spring acts as high rate spring and adds to the suspension springs rate to effectively produce a very high spring rating resulting in a hard ride. These rubber buffers should either be replaced with the correct item or shortened the appropriate amount.
    When a coilover setup is put in place obviously this supplementary spring is removed with the shock absorber.
    If dropping more than 30mm then really shortened shock absorbers may be needed to provide enough bound/ rebound damping distance .
    Another common issue people forget to deal with, and this affects both springs and coil over installs is to reset the suspension arm inner mounting point position for the new static position of the arm.
    The inner joints are rubber bonded bushes, these only have a limited amount of travel and lowering the car without resetting these effectively puts a permanent load in the bush. This itself takes some compliance out of the suspension and makes it stiffer apart from eventually wrecking the rubber bushes.
    The suspension needs to be put in what will be it's new static position and the bolts on any rubber bonded suspension arm joint loosened to allow the bush to unwind. Then tightened again.
    Properly designed lowering springs such as the Eibachs have much time and effort put into them to not only lower the car but provide ride comfort, they are designed to work with the existing shock absorbers and because the spring rate will not be that much different from stock they work well. They only work at one height so the spring rating is optimised for that and there are many different versions available for different axle weights.
    Coilovers are a one stop solution, the spring ratings are not optimised for any particular axle weight range , the spring ratings will be higher as this will be needed to support the vechicle as the weight changes with the potentially smaller amount of suspension travel that you may have if running a lot of drop.

    In my case I just want to get rid of some of the arch gap and the lowering will help the handling but not at the expense of ride quality or practicality. I tow a caravan with my car and we have some fairly major speed bumps where I live.

    Eibach springs at £140 are a much better deal for me than £500 plus on a set of coliovers.

    4 each side at the front and about 6 each side at the rear on a quattro as there are many suspension arms, so call it a round 20.

    But this bit says that I am rite in what I say about it starting to damp:
    in a coil over set up differ to ones on a standard car. A coil over is designed to work over a large range of adjustment so the starting point of the shock will vary depending on the installation height.
    Also they do do ones for your axle weight as mine is 1081kg all I'm saying is you will have a bumpy ride this is why my sline is so bumpy as its 20mm lower as standard and when I put coilovers on it should be a better ride, I hope you will be having a 4 wheel alignment done after???

    What I am saying is the shock aborber in a coil over and the shock absorber on a car work the same way. The amount of lowering has nothing to do with when the shock absorber starts to damp.
    There are many other things that contribute to ride quality. Usually people with S line cars have 18 inch wheels or larger, these have lower profile tyre walls. If you have XL rated tyres these tyre walls will be even stiffer. All this contributes to a poor ride quality.
    I will be running my car on 17 inch rims with 235 /45 /17 tyres so won't have so much of an issue.
    Most of the time a 4 wheel alignment won't actually help you sort problems out that occur when a car is lowered.
    The biggest change that occurs when a car is lowered especially with the front suspension set up on these cars is camber, and that isn't adjustable unless you spend £500 + on adjustable top arms.
    lowering 30mm will probably induce a bit more camber all around but this helps turn in. If you go a lot lower you get excessive camber issues which can lead to tyre wear.
    I will check the toe and if necessary get that adjusted.

    I have 245/45/18 on my sline and I've gotta say the ride is horrible, I also have a 2010 hilux invinsible with a 3" lift and 32" tires and when I fitted them the ride was improved no end, I've lowered at least my last 8 cars and tried springs on 2 but regretted it rite away and switched to coilovers and the ride was improved massively I have quite a few friends who have cars lowered and probably 6 who have air ride which I've gotta say I like the look when stationary but not so keen on the ride and the rest of my friends run coilovers as they don't like springs not just for the poor ride but they ruin your shocks too. 30mm shouldn't cause too bad camber issues but you will need a four wheel alignment if you don't want your tires to scrub just google it and see on other forums like the A5oc there is a thread and everybody on there is agreeing if you go lower you need wheel alignment, mines booked in next Thursday at awsome gti who are fitting coilovers and wheel alignment for £150 there is a bit of camber that can be added but not a lot at all its recommended to have a wheel alignment every so often anyway let alone messing about with the suspension. I recommend it is done, but it's up to you at the end of the day. I do a lot of modifying cars Audi A4 b8 is a new one to me but they all work pretty much the same springs feel to me like the car is riding round with 5 people in there and the boot full of bricks.

    Yeah would say go aftermarket for shocks as Eibach's slightly lower than sport, mines on AP dampers (b6 though, not a b8 like all you rich dudes haha)

    Got my coilovers fitted and wheel alignment done love it rides real nice not much change from standard as far as ride comfort, will be going lower after Christmas when new wheels are fitted and they have settled as they prob will settle another 5-10mm from the pics :)

    Think my adjusters need to come out as I expected it to settle a bit lower than it has so they gotta go, but more camber on rear to suit and I'll be ok to take them out I think as it scrapes a little bit and that's with 25mm spacers on wheels but if I do put more camber I should be ok to go lower without having to go any smaller on spacers 😜

    Fitted the Eibach Pro springs yesterday. After having a look on the net and seeing how Audi do it in the workshop repair guide on Elsa Win I thought It wouldn't be too difficult.
    Started off with some before shots,

    [​IMG]

    [​IMG]

    [​IMG]

    My car is an SE with the standard suspension, measuring the height from the wheel centre to the top of the arch lip it was 390mm all round.

    Started at the front and removed the front strut with not to much of a problem, Took the spring off and compared it with the Eibach item,

    [​IMG]

    The Eibach spring is a full 60mm shorter than the standard spring. Same number of coils but the Eibach one is 15.5mm thick and the standard spring 15mm.
    The gumph on the Eibach site says that the standard bump stops are used but in my experience when you lower a car to keep some ride comfort you need to shorten the bump stops otherwise the ride can be quite harsh.
    There are three lengths fitted as standard


    Front

    8K0412131E 1BA 81mm

    8K0412131F 1BE 72mm

    8K0412131G 1BV 66mm

    I shortened mine to 72mm the same as the S line suspension set up. Just need to hacksaw 10mm off the top of the bumpstop and it fits back fine.
    It was really easy refitting the front spring on the shock as it was so much shorter didn't even need the spring compressor to refit it.
    I reset the suspension inboard joints for the new ride height.
    By undoing the inboard bolts on the top 2 arms and the bottom 2 arms, then jacking the strut up till it's at the normal laden position.
    You can then tighten the inboard bolts, This stops the rubber bushes being permanently preloaded which helps there life.
    You need a T55 Torx to hold one of the bottom arm bolts is you decide to undo it.

    The rears springs were interesting as I thought they would be, On my old Passat just a matter of undoing the shock absorber lower mounts and the rear axle would drop down enough to remove the springs. Not so easy on a quattro.
    The official way of removing the rear spring is with a special spring compressor, normal spring compressors mostly won't fit due to the confined space. By putting the spring compressor I have inside the coil spring rather than on the outside, and using some Pretty sturdy ratchet straps managed to compress the standard spring enough to remove it.
    Again the standard springs were 60mm longer than the Eibach springs.

    [​IMG]

    This proves very useful as the Eibachs slot straight in with no spring compressors.
    The rear shock absorber bottom bolt is ridiculously tight and had to use a breaker bar and the jack to undo them. Again there are 3 lengths of rubber buffer.

    standard suspension 1BA
    8K0512131 140mm long

    Sport suspension S-line 1BD, 1BE
    8K0512131B 118MM long

    Adjustable suspension and 1BV, 1BL -30mm suspension
    8K0512131D 110mm long

    I took 20mm off my buffers to make them the same as the S line ones.I didn't have time to reset any of the rubber bushes on the rear suspension as it was going to be dark by the time I finished. Will do this at some point in the future. You need to watch what you are undoing on the rear as some bolts are eccentric and adjust camber and toe.

    And the end result

    [​IMG]

    [​IMG]

    [​IMG]

    Currently seems to have dropped about 40mm at the front and 30mm at the rear, when I reset the bushes at the rear it may drop a few more mm.
    Car drives really nice, I wouldn't say it's that much firmer than standard, passed the acid test by getting over all the speed humps in Heath Hayes high street easily, a place I never took the Passat as they are monsters :roll: .
    Less roll when pushing it around corners, the kind of thing you expect.
    When I have finished tweaking it will take it and get a full 4 wheel alignment done.
    These have been recommended and get very good feedback on the net.

    Has anyone had any scrapings with either the Pro or Sportline kit?
    Any issues with speed bumps or anything that will cause it to scrape at the bottom?

    Here in London there are tons of speed bumps and wondering if there are issues.

    You will be fine with springs as they aren't much different to the sline suspension. I was in Birmingham a couple week a go though an couldn't get in to a morrisons car park I had to reverse back on to a main road the bloody speed bumps were mountains lol

    I already got the sports suspension, if it's only going to drop 10mm is it worth forking out £300 to have them fitted and wheel alignment?

    I thought the Eibach Sportline was more of a drop than the Audi S line drop?

    Bet you must of gotten funny looks reversing out lol

    You will get more than the sline suspension but not a lot more, for £300 I would say do it. Yeah your not kidding I did, there is only one other speed bump I know of around here that I can't get over, I don't get why there isn't a standard height for speed bumps they are all bloody different heights.

    Is your car lower than the S line drop, and by how much? I know you have coilovers.

    That's the only thing i'm worried about, scraping the car over speed bumps if I get the Eibach Sportline.
