Can I jump on this and ask for advice from the group. I have a 2017 2.0 tdi non-DCC 4x4 SEL Estate, standard ride height (I assume) and a towbar. I have some pretty soft springs on mine;- undulating, bendy roads are an uncomfortable challenge. I quite often have a fair amount of weight in the car. I don't want to lower the car and, as I have decided to keep it for the duration, I am happy to buy decent kit that will last. So - if I want to firm up the ride and handling, maintain comfort and ride height and have the car able to be comfortable solo and well-loaded - what are the suggestions?

 

What are the OEM part numbers are the front and rear springs?

 

Once you have found that out, you can perhaps look at increasing the stiffness of the rear springs such as going up one, two, or three in the hierarchy.

 

The Kilen online spring catalogue suggests that you might have 5Q0411105GN front springs and 3Q0511115M rear springs. You can see in the chart below that 3Q0511115M is 5th in the hierarchy. So if that's the rear spring OEM part number then perhaps look at rear springs with OEM part numbers 3Q0511115N, 3Q0511115P, and 3Q0511115Q. Which one you choose will depend on availability of aftermarket springs and their specification, plus your own preference.

 

Listed below are the ten standard ride height rear springs for the Superb MK3 4x4. They form a hierarchy from the softest and shortest spring (3Q0511115AH) to the longest and stiffest spring (3Q0511115BC). Not surprisingly, your factory rear springs will be somewhere in the middle around 3Q0511115M.

1. Mine is not sportline and nor (as far as I know) does it have sports suspension.

2. But the part numbers you list above will for the Eibach springs will improve the ride without lowering the car?

3. Plus you suggest Bilstein dampers too... Have I got that right?

 

1. mine also isn't Sportline, L&K 2.0 TSI 280ps 4x4

2. yes, will improve, they are ~ 15% stiffer than OEMs

3. optional  but highly recommended, as it won't increase installation costs (just search for non DCC version)

 

Just wanted to thank @MartiniB - I very nervously took the plunge and had my garage fit the Eibach Pro Springs he listed for the Kodiak. I fitted these because I didn't want to lower the car. Mine doesn't have adaptive ride so I fitted the Bilstein B6s. I cannot recommend this upgrade enough. The car IS firmer - but there is no float, no wallow. The body control is superb, it corners so well. Where I live there a couple of roads that really find cars out. And they really did find out my Superb before. Now, it is genuinely a different story. Thanks - and I am so delighted I did this.

I'm so sorry about my limited knowledge of English,
but how these phrases go together?

i.e. he cannot give you enough praise 😀

@MartiniB

Exactly this - .e. he cannot give you enough praise 😀

I completely recommend the upgrade.

 

The only unintended consequence is that I now need to tackle adjusting the HID headlights (they're aiming too high). I had previously thought they were auto-levelling but it appears  that we still need to set them at the right height...

Have you thought of replacing all the rubber bushes, which deteriorate and result in softer ride, and make spring do more work.

 Changing to polyurethane bushes add stiffness and will outlast the car giving an improved ride.

 

Honestly no I haven't. The car has done 110,000 miles and I asked the garage to check all the bushes and linkages and they reported back that they were all fine. And given the body control now - (I'm no factory test driver but...) I think they're ok for the time being. I also feel that the car is just the right level of firm, happy with rubber rather than polyurethane...
