Thanks @Carlston. I’ll shop these springs and report back with the results. Already running a Hardrace 25.4mm (hollow) rear sway bar and the improvement was immense and almost entirely removed body roll during day to day driving. That was one of the softest aftermarket sway bar options.

 

If you do try 3Q0511115M rear springs, I suggest you measure the wire diameter before fitting. I've seen these 3Q0511115M springs listed on autodoc with three different thicknesses, 12.5mm, 12.75mm, and 13.0mm. Most were listed at 12.75mm.

 

If they have a wire diameter of only 12.5mm it might be better to return them to the seller for a full refund and not fit them, as I wouldn't expect them to be stiffer than 3Q0511115AL just longer...perhaps around 6mm longer. So your rear end might be raised 6mm but the stiffness might be the same as the 3Q0511115AL springs.

 

Unfortunately, Kilen and Lesjofors don't list the specification of their springs.

 

The Eibach R21093 is the only 3Q0511115M rear spring listed with a claimed wire diameter of 13.0mm, so that one might be worth trying as it should be the stiffest 3Q0511115M spring if the claimed 13.0mm wire diameter is true.

Thanks for that. Do you happen to know who the OEM is for stock springs? Is it Monroe (who also make the DCC shocks)?

 

Here in Australia we have KYB and Eibach with a local presence. The Eibach’s appear to have the shortest spring lengths with defined wire diameter so looks like a good option. I’m also looking into parts directly from VW.

 

I wish it was possible to search which make and model specs actually used these parts so I could just go to a wrecker.

yes, OEM is Monroe -

list of choices:

1. OEM Monroe

2. Bilstein B4 DampTronic

3. Bilstein B6 DampTronic

and two lowering coilover sets

4. KW Street comfort

5. Bilstein B16 DampTronic

 

Bilstein had long period with parts shortage, front pair of B6s i waited 5 months and rears 13 months, last not installed yet

(ordered from Germany, Tuning-Expert.com)

to avoid lowering i chose from weightier car -

from Audi Q2 for Superb front axle

and Superb AWD springs for FWD Superb

as result front axle go 0mm loweringm and rear got ~12 mm lowering

    If you allow me, I thought a lot about the springs, following @Carlston's instructions, I ordered the ones corresponding to my model from the Lesjofors catalog (GN and M) and Koni Special Active shock absorbers, the latter I hope will provide something more than some Sachs or some B4.  I am waiting for your installation that I will tell you once I have tried them.  With this I want to tell you that you can do the tests that you think are necessary, but more or less everything is clear with this topic.  

     

    What springs do you have now?

    5Q0411105GM front springs and 3Q0511115AL rear springs. Pretty soft for such a large car.

    Muelles delanteros 5Q0411105GM y muelles traseros 3Q0511115AL. Bastante suave para un coche tan grande.

    My model is the TDI 190cv 4x4 Kombi, GM and AL are a bit softer than those that correspond to me (GN and M) right now I have the raised suspension for bad roads (PPD) and I have HS and AS, they are quite harder than the standard ones but the car is a pirate ship from what it moves.  If you are going to pull a caravan maybe you should put an N, I do not think that the difference in hardness is critical in any case and it is almost better to go too hard, since very soft will make the car sink with its own weight.

     

    If you want something harder, the next combination is GN and M and the following GP and P. Here you decide.  If when they install mine it is soft, I will go for the following configuration that I tell you.

    Seems like @Carlston got the insites 🙂

    I have a 2019 Superb Combi/Estate 2.0 TDI (FWD 150hp) DSG, but without DCC.
    I am out replace the standart (very soft) springs with the springs found on the "Sportline" edition (that is around 15mm lower).

    My current spring OE numbers are:
    Front: 5q0411105gn
    Rear: 3q0511115al


    Do anyone know the OE numbers for the "Sportline" replacement springs and what are your recommendations?
    (I am not looking for Eibach pro-kit, H&R etc. with +30mm lowering of the car, that is way to much for me).

     

    PS. I have searched all over - attached is what I got so far 🙂 

    Skærmbillede 2023-02-07 kl. 14.23.29.png

    @MartiniB Okay I see your point, but in my case wishing for a 15-20mm lowering of the car incl. getting rid of the "boat soft feel" what specific front and rear spring should I ordre from lets say Eibach? I can not figure it out 😅

    Most of the below eleven "lowered ride height" rear springs are not available aftermarket. However, weight range 3 (0YC) to weight range 6 (0YF) "lowered ride height" rear springs are available.

     

    I suggest you try the weight range 3 (0YC) or 4 (0YD) "lowered ride height" rear springs first, because the two stiffest springs might make the car feel like an empty transit van, ie. far too hard.

     

    The weight range 3 (0YC) "lowered ride height" rear springs are about 10% stiffer than your current 3Q0511115AL.

     

    The weight range 4 (0YD) "lowered ride height" rear springs are about 20% stiffer than your current 3Q0511115AL.

     

    The weight range 5 (0YE) "lowered ride height" rear springs are about 30% stiffer than your current 3Q0511115AL.

     

    The weight range 6 (0YF) "lowered ride height" rear springs are about 35% stiffer than your current 3Q0511115AL.

     

    You might find that weight range 5 and 6 springs are only comfortable if you are carrying five adults and all of their luggage. 30% to 35% stiffer springs is a ridiculous amount to increase the stiffness of the springs by.

     

    When working out the change in unladen ride height, you need to factor in that stiffer springs don't compress as much under the same load. So a stiff spring that looks like it will lower the car by 40mm might only lower the car by 30mm.

     

    Notice that the Eibach ERL (Eibach Replacement Line) springs that I've linked to at the bottom of this post, are sold to replace more than one OEM part number (except the weight range 6 spring), so might not be an exact match to the OEM part number that you want. However, I suspect for your needs they will be close enough to what they are sold to replace.

     

    When you purchase aftermarket springs online, check them carefully to make sure that they are what you ordered. With online sales, the seller gets a lot of returns and often the wrong springs will have been put back in the box.

     

    Weigh the spring, measure the wire diameter and the uncompressed length, and count the number of coil turns. If the springs don't seem right after fitting, you want to have those details so that you can investigate further and work out what the problem is. So often, people find that their new springs are either too high or too low, and don't know the specification of the springs that they have just fitted.

    @MartiniB Está bien, entiendo tu punto, pero en mi caso deseando una reducción del automóvil de 15-20 mm, incl. deshaciéndome de la "sensación suave del barco", ¿qué muelle delantero y trasero específico debo pedir, digamos Eibach? No puedo entenderlo  😅

    Also value the installation of OEM stabilizer bars from the Golf R or Kodiak, I have installed them on both axes and it is an almost more important change than the springs and cheaper, especially the rear one that you can put on yourself.

    Just to add to my previous suggestion that the "lowered ride height" rear springs for the Superb MK3 2.0TDI 150HP FWD DSG estate should be either 3Q0511115AA or 3Q0511115AB.

     

    "Bigeater" on another thread has a Superb MK3 2.0TSI 280HP 4WD estate "lowered ride height" with 3Q051115AC rear springs (and 5Q0411105HE front springs). Now not only does the 280HP have a lot more power than 150HP, but being a 4WD it has considerably more weight over the rear axle. This confirms my thoughts that the choice of rear springs with "lowered ride height" should be made from 3Q0511115AA or 3Q0511115AB.

     

    Many people who stiffen up their cars make a beginners' mistake of overdoing things, such as choosing springs and anti-roll bars even stiffer than the already stiff Golf R. One guy even commented that he had fun in his car that he stiffened too much for a year, but then the novelty wore off and he was left with a car that was simply too stiff and uncomfortable.

     

    Maybe think about the Mazda MX-5 and how that is set up. It has never been a very stiff sports car, but it is fun and dynamic with the right balance of stiffness and suppleness.

     

    Another important point, is if you are going to use the standard shock absorbers they might not provide enough damping for springs that are much stiffer. Perhaps look next at RARB (Rear Anti Roll Bar), maybe from the Superb MK3 4WD 280HP. I would do one thing at a time and carefully assess each stage before deciding on the next one. So first slightly stiffer rear springs, and then slightly stiffer RARB.

     

    Then you can decide how much to drop the front to match the rear, and the stiffness of the front spring...and then whether a stiffer front FARB (Front Anti Roll Bar). However, I doubt the FARB will be necessary if all the other modification so far have provided the car with a nice balance.

     

    Before even considering a FARB, I would be looking at the shock absorbers. Are they working well and would new ones provide improved performance, etc.

    browse link i posted above

     

    @MartiniB I have checked your link and maybe I am a bit “slow” but it seems like you are listing DCC springs?

    I have also checked you excel line up - but I can see the “matching” front spring for:

    3Q0511115AB (+20% stiffness)

    https://www.autodoc.co.uk/eibach/18112504

     

    NB it should match both "1JC+0YD" and lowering height so that the loweribg height is the same front and rear.

     

    thanks again for you inputs 🙂

    NB it should match both "1JC+0YD" and lowering height so that the lowering height is the same front and rear.

     

    An update on my current thoughts.

     

    I think you should fit the rear 3Q0511115AB (+20% stiffness) "lowered ride height" spring first, and then see how much the front end needs lowering.

     

    The equivalent VW Passat 2.0TDI FWD DSG estate uses 5Q0411105CH front springs, as it is set up to give a slightly more sporty ride.

     

    If you use this 5Q0411105CH front spring it should drop your front end by about 10mm to 15mm.

     

    MartiniB found that he had to fit longer front springs when he fitted Eibach sports springs, to prevent the front  looking lower than the rear.

     

    I would advise against fitting anti roll bars until you have finished fitting satisfactory springs and possibly new shock absorbers depending how your current shock absorbers perform with the new springs.

     

    After than, you might find that your car is no longer floaty, boaty, and doesn't need stiffer anti roll bars. One problem with stiffer anti roll bars is that they make going over partial speed humps harder when they kick just one wheel up at a time. Another problem, is that it might not be easy to decide exactly what anti roll bars to fit. The Skoda parts catalogue doesn't make it clear exactly what the hierarchy of the anti roll bars are. It looks like the Superb MK3 4WD 280HP uses slightly stiffer front anti roll bars than the lower powered FWD cars.

     

    After you fit the 3Q0511115AB rear springs, can you put a side photo up of your car, so we can work out if the front needs to be lowered by 10mm to 15mm, or 30mm? If 30mm, then springs shorter than 5Q0411105CH (from the Passat B8) would be needed.

     

    In the link below for the 5Q0411105CH front Passat B8 spring, notice that the Eibach R20796 is listed at 311mm, the Sachs 993 931 is listed at 307mm, and the KYB RA1343 is listed at 302mm. These springs will often be a little different to the length that they are listed at, so the KYB won't necessarily be 9mm shorter than the Eibach. They might turn out to be a similar length, but you just don't know until you measure them yourself.

     

    5Q0411105CH (from the Passat B8) (claimed length 302mm to 311mm)

    https://www.autodoc.co.uk/car-parts/oem/5q0411105ch?search=OEN 5Q0411105CH&supplier[0]=85&supplier[1]=32&supplier[2]=112&supplier[3]=85&supplier[4]=32&supplier[5]=112

     

    Eibach R18812 sold to replace 5Q0411105HF (length 282mm, wire diameter 12.5mm)

    https://www.autodoc.co.uk/eibach/17876012

     

    If the 5Q0411105CH is too long, the Eibach R18812 sold to replace 5Q0411105HF looks like a good choice. Although, this spring doesn't appear to be any stiffer than your current front spring. Because you are going for a much stiffer rear spring, maybe 5Q0411105HG would be a better choice as it's a little stiffer than 5Q0411105HF..

     

    Eibach R14665 sold to replace 5Q0411105HG and 5Q0411105HH (length 287mm, wire diameter 12.75mm)

    https://www.autodoc.co.uk/eibach/17875999

     

    Also, it looks like the 5Q0411105HG is the stiffest "lowered ride height" front spring listed in the Skoda parts catalogue for the Superb MK3. Bearing in mind, that someone mentioned that the Sportline springs are soft, this stiffest in the range "lowered ride height" front spring might give you the stiffness that you want and be a good match for your 3Q0511115AB rear spring.

    Wonderful thread 👍

     

    Iam about to order these 3Q0511115AB for make my sportline combi stiffer in the rear when towing. And if I have understand everything right is shuld be the same ride height but higher load without sacking / boaty?

    Your Superb MK3 is 4x4 and you want to tow a caravan. The fella who is considering those 3Q0511115AB has a Superb MK3 2WD and wants his car low and to handle like a Ferrari. He is also in the process of trial and error, where things could easily turn out different from what he is expecting. Two different cars and two different setups. The 4x4 weighs more than the 2WD so uses different springs, especially the rear springs.

     

    It's best to find out the OEM part numbers of your current springs before doing any modifications.

     

    One Superb MK3 estate owner who was towing a caravan had a broken rear spring and felt sure he needed much stiffer rear springs. However, the garage would only fit the springs that the car left the factory with. The owner found out that these new springs were fine, and that he didn't need much stiffer rear springs after all.

     

    As aftermarket springs are cheap on ebay, it might be best to try new standard rear springs, in case the original ones have simply started sagging...and then take it from there.

     

    If you go up by more than about 10% in stiffness, you might find that the springs become uncomfortably stiff when there's not a heavy load in the car.

    Fabulous thread with very useful information thanks folks! I have a 2019 Superb Wagon, 2.0 TSI 16 (DSG, Petrol) that I want to fit stiffer rear springs to (for towing, carry heavy boot loads, towbar bike rack etc) and am tossing up between the 3Q0 511 115 M (weight range 5, standard height) and the 3Q0 511 115 AR (weight range 5, increased height). 

     

    My understanding is that AR spring involves about +20mm lift, and would also require a 90mm rubber buffer (as opposed to the 70mm standard) - is this correct?

     

    Also, obviously either stiffer spring will make the unladen ride harsher (which I am fine with), but can anyone comment as to whether the standard height spring (M) or the lifted spring (AR) will adversely affect handling when unladen?

     

    Any help much appreciated, you guys rock!

    Superb MK3 increased ride height rear springs only appear to be available aftermarket for weight range 6 to 9, so no equivalent to 3Q0511115AR.

     

    For a front wheel drive Superb MK3, I suspect standard ride height weight range 5 rear springs would be the best compromise for a mix of unladen and heavily loaded use. The weight range 6 rear springs might make the ride too hard when the car is driven unladen. Bear in mind, that the standard rear springs might only be weight range 3.

    Thanks Carlson, your thoughts are much appreciated! 👍 Think I'll go with the standard height, weight range 5 then (3Q0511115M)

    Hello group!! :) I wanted to restore the standard suspension height in my Superb 3 Estate 2.0 tsi 4x4 272 whit towbar

    with the off-road package

    Orginnal setup

    Front spring  is 5Q0411105HS PR-L31

    Rear spring is 3Q0511115AS PR-UC7+0YF

     

     

    So, following the topic, I chose spring

     

    Front 5Q0411105GN PR-L08

    Rear 3Q0511115N  PR-1JA+0YF             Is this a good choice?

     

    And second tinks . I wonder if I can put a B6 shock absorber in the UC7? Will 15mm have a problem on installation or use? thx for help
