Hi

 

So I'm going to replace the stock springs (sport suspension) on my Octavia Mk4 with H&R Lowering springs art.nbr. HR286395 (FrontAxle45/RearAxle35mm). Been reading the MK3 forum and after replacing the springs some say there's a need to

- recalibrate the wheels

- recalibrate the radar

- recalibrate the DCC (if you have it like I do)

 

Seems to be quite a few people on here who's put on lowering springs on their Octavia Mk4 and I would really appreciate if they could explain

- what will be the effects of NOT recalibrating the radar (f.eks. are the matrix headlights going to point to low? Will the ACC be affected? Will there be an error code? etc)?

- what will be the effects of NOT recalibrating the DCC (some MK3 owners did not calibrate the DCC after lowering and that seems to have worked fine, but will it for the MK4?)

 

Thanks

Wheel allignment to be done for sure.

I have a report of before and after lowering.

During wheel allignment a good garage also does recalibrate the radar.

I did not recalibrate the dcc. Still looking into that who can do it.

 

Lowered with Cobra springs nowm

Interesting. How did you find your non-recalibrated DCC working after lowering your car compared to before?

 

(Can't find the Cobra springs for the sedan/hatchback so I assume you've got the estate)

Yess i have an estate.

But the DCC is still working fine in 99% of my driving.

But sometimes on a a puthol ish I suspect the dampers should act differently. It smashes through now on normal mode.

I drive between normal mode and max sport.

Well sounds like the DCC has been some what compromised since your lowering. I guess setting the DCC to max comfort is out of the question now, or?

The garage that's going to do the work on my car have a lot of experience modifying cars and are really good at the mechanical side of things however they don't have any experience recalibrating radar nor DCC.

So, the garage you used were able to recalibrate the radar but not the DCC? Did they tell you why?

 

(I also assume you've got a VRS since your nick is DutchVRS)

 

@Anth1s Did your garage recalibrate the radar and the DCC?

Hey!! 
 

soo I received my H&R springs and Eibach spacers (10mm/15mm) and had them done yesterday 😈😏

My car has DCC and I did all works in Skoda official dealership.

I can say I thought the ride will be harsh but to my surprise - it almost did not change!! What i noticed is no more stupid roll-overs on comfort, car handles tight and awsome. As sport car should handle 😈

regarding DCC settings - feeling is that every mode got a lil bit stiffer, like 10-20% tops. For me - its advantage and nice thing 😅

of course springs need to adjust properly over the week but overall - car looks SO MUCH better now 😍

 

Anyone knows which H&R lowering spring to choose for 1.5 e-tec sedan?

I came to the following conclusion before placing my order (please correct me if I'm wrong and contact H&R if you want to be 100% sure):

 

For the H&R springs for the Skoda Octavia NX,

- it depends on your cars technically permissible mass on its front axle and

- whether your car has twist beam (also known as torsion beam) or multi link rear suspension

 

The former can be found on the EC Certificate of Conformity if your car has been manufactured in the EU (there might be an equivalent CoC in Asia?). On mine it says 970 kg.

I don't know how you would go about finding info about the latter in Singapore however I know that my car has the twist beam and I've got the 1.5 TSI non-electric. I think I've read somewhere that only the VRS has the multi link but don't quote me on that.

 

Article number at h-r.com

28639-5 Up to and including 1000 kg permissible mass front axle, twist beam

28639-6 Greater than 1000 kg permissible mass front axle, twist beam

28639-9 Up to and including 1000 kg permissible mass front axle, multi link

28639-10 Greater than 1000 kg permissible mass front axle, multi link

 

 

So I've now replaced the stock springs  with H&R Lowering springs art.nbr. 28639-5 and to answer my own questions:

I haven't noticed any negative effects whatsoever.

I haven't noticed any negative effects whatsoever. The DCC works flawlessly at both extremes (max comfort vs max sport).

 

No scraping nor tires touching the wheel house driving over large speed bumps.

 

According to the garage, all that was needed was a wheel alignment.

 

The ride is great and the car finally looks like it did in the car configurator (in regards to ride height).

 

 

 

I noticed some posts in German FB group about recalibration of the assistance system when people did lower their cars. Not sure if this is really needed or not.

Pretty accurate depiction of what my car looks like now:

https://www.tuningblog.eu/en/categories/cars-from-az/sport-springs-skoda-octavia-327799/

 

Good to know is that the car in the above pictures has original wheels 7,5 x 18 with 48 mm offset, tires 225/40/18, and wheel spacers (10 mm front, 12 mm rear)

The Octavia MK4 uses bigger outside diameter tyres than the previous three generations.

 

Hence the outside diameter of 225/40R18 tyres is too small for the Octavia MK4. If you do use them, the speedo will massively over-read. An indicated 70mph on the speedo will translate to about an actual 63mph.

 

The standard 18" tyres on the Octavia MK4 are 225/45R18, not 225/40R18.

Well that's not really the point now is it @Carlston. The point is to inform the viewer of the pictures about what they are looking at. And if the owner of the pictures (H&R) says the car in the pictures has tires with dimensions 225/40/18 then I am sure as hell not going to write something else.

 

Show some appreciation for what I'm sharing instead of being such a downer....

Buying the wrong size tyres could cost someone hundreds of pounds, so I do think errors like that should be corrected.

Reading the

 

I found this on page 351 & 352:

...

If "adjusting the axle geometry" is what's being done doing wheel alignment, then the ACC needs calibrating.

 

And on page 361:

...

 

So, I guess I need to have a conversation with the mechanic that did the job.

I am driving almost a year with RS and H&R lowered - acc works flawlessly. No issues whatsoever and i did not recalibrate it. And mine is DCC

 

i only did aligment and headlights calibration 😄

Hi just to revive an old title,

I have just ordered an octavia 150bhp diesel with dsg box not a vrs.

 

My question is I will want to lower it 15mm not really looking to go more if i replace the springs with vrs springs will that work and give me the 15mm drop im looking?

Hi all, 

 

Luckily for me this thread has been (semi) revived!

 

Wondering if people recommend Eibach Sportline lowering or H&R. I've heard Eibach was a bit softer and results in a smoother ride but any input is appreciated.

 

Thanks.

Never tried Eibach. Will do next time though. Had some email conversations with them and they seem friendly and eager to please.

 

I am a bit disappointed with H&R, mainly with their so called "customer service" and their poor documentation. Also, the provided replacement front rubber buffers I got makes a squeaking sound noticable at low speeds when turning and going over bumps. Lubricating the rubber buffers is only a temporary solution since the squeaking returns after awhile (in my case) and the rubber buffers cannot be easily accessed (i.e. without tools and without jacking the car. Somebody, please tell me I'm wrong!). 

 

Can't say that the H&R lowering springs for the NX3 non-RS that I've got feels any stiffer than the original springs. However, I've got DCC, and I believe that makes it harder to differentiate between the springs. Using the "Normal" mode, which I guess would be the closest suspension setting to a car without DCC, the ride is still soft with the H&R springs.  

Recently found two H&R documents which I wish would have been available, with their current contents, when I bought the H&R springs.

 

H&R has named the link to the first document "Certificate: 28639" (the title contained within the document is "TEILEGUTACHTEN EXPERT OPINION ON A COMPONENT") and the link to the other "Installation Manual: HR01-X002A04" ("General installation instructions HR01-X002A04 for Sport Springs.")

(The documents I refer to above are the ones associated with the springs I bought, ie the 28639-5. Other springs might have similar documents with different names.)

 

The documents can "easily" 😜 be found in the "Electronic parts catalog" at www.h-r.com:

After entering the "Electronic parts catalog", select manufacturer ("Skoda"), select model ("Octavia"), select version (e.g. "OCTAVIA IV (NX3)), select engine (e.g. "1.5 TSI DPCA"), select type of part ("Sport Performance Springs"), click the icon for "Parts list" (picture of a right arrow+page+cog) which is placed directly below the "Part Number" (e.g. "28639-5"), select the "Details" tab in the pop-up window, the links to the documents can be found beneath the heading "Documents/Illustrations".

 

I highly recommend reading both these documents before buying lowering springs.

 

Examples of contents in "Certificate: 28639":

- "The setting of the headlamps is to be checked"

- "When fully relieved, the springs must be free from play in axial direction"

- "The subsequent suspension alignment has to be done immediately"

- "Fitting of the coil springs, the subsequent suspension alignment as well as a required calibration of driver assistance systems is to be made according to the guidelines of the vehicle manufacturer as well as the modification instructions of H&R"

- "Not for vehicles with CNG-drive (Compressed Natural Gas)"

 

Examples of contents in "Installation Manual: HR01-X002A04":

- "After installation wheel alignment, headlights and brake-power regulator have to be checked and adjusted to the factory specifications if necessary. A required calibration of driver assistance systems is to be made according to guidelines of the vehicle manufacturers"

- "The car must stand on the ground when the damper fixing nuts and bolts are finally tightened, i.e. axle load must be the same as in drive mode. Otherwise, the damper will suffer permanent side force, causing noises and a reduction in it’s life"

 

Just installed the Eibach Sportline springs. Going for an alignment tomorrow but the car feels normal, maybe a little stiffer on rebound than stock but the DCC settings all seem to work as they should. I was told by the very trusted shop that did the install that the radar and headlamps would not need resetting as the 30mm drop isn't enough to warrant it. I haven't checked the high beams but I will see how they go. I had H&R springs on my last car and I can already tell that these Eibachs ride better. Maybe its the DCC doing its job. The car is now looking closer to how I want it too!

Nice! All you have to do now is to change the front emblem to all black and you will have one mean looking machine...😁

Can you share a little bit more details on which exactly springs you installed, because I see two different types at least for the VRS model ( can't find any info about what's the difference between them ).

I am currently trying to decide if I should try first with lowering springs or go directly with a new full coilovers set. For both thinking about the KW Suspension: DCC Plug & Play or the sport springs. The first one is much expensive then the second option and if I don't like the way it handles compared to the OEM DCC suspension I would definitely be very unhappy. But in case I go with lowering sport springs with maybe updating the top mounts also in case I don't like the extra harshness compared to the OEM springs I can easily replace them.

So after almost a week of driving, having an alignment done and going on some longer distance drives. I’ve noticed that the springs have settled further. The car definitely rides firmer than it did. I am looking into doing a DCC recalibration and possibly radar. I hope I can regain some of the damping characteristics the car had when stock.

To answer your question about which springs specifically the part number is: E20-79-016-03-22.
