3.6 4x4 OEM springs as lowering springs to a 4x4 tdi?

Featured Replies

Hi.

 

Little backround first. I have a 2011 Superb Estate 4x4 with 2.0 tdi engine with DSG. Car came originally with the highest possible rough road package from the factory (PR code G56). Few years back I was stupid and decided to lower my car with H&R -40mm springs as I thought the car was wayyy to high for my taste (but I wanted the 4x4 because winter is snowy in Finland). So I installed the H&R -40mm Springs with Bilstein B4 "sport" oem style shocks (shorter shock body or something like that, can't remember anymore what the difference was). Went with the H&R as they had certification papers to be fitted to an 4x4 model, and Eibach didn't (we have to MOT lowering springs here in Finland and I couldn't have done it with Eibach springs for this car without proper certifications).

 

Anyhow the car went lower that I had hoped, as front was lowered 55mm and back 50 mm, so more than the H&R springs were supposed to. Ever since, I have kind of beared the lower that expected height of the car, as on summer it's quite good height. A little too harsh on bumps and rougher roads, but good on the smooth highway roads. But in the winter, it's just way too low as the botton panels scrape every snowball on the road and sometimes the back panels even hit the floor of my garage when driving in.


So, I want to lift the car, but I don't want to go back to the factory spec rough road height and I have considired to fit the OEM 3.6 VR6 springs instead. I have also considered liftkit spacer plates under springs, but those will cost more than Bilstein B3 OEM VR6 springs from autodoc. Rideheight on these 3.6 cars from the factory looks quite OK to my taste. Could these work on a 2.0 tdi engined car also, or am I better off with some other brand springs with less lowering (which are certified to be fitted to a 4x4 model)?

 

I have added pics of the car with OEM rough road package springs and with my current lowered H&R springs. Rideheigthwise I would like to find a good middleground between these two and maybe a bit softer ride as over the years, the H&R seems quite harsh on any other than smooth tarmac road to my taste. And don't mind the drivers door, I know it's different color, but it was painted by previous owner and seems way much worse on pics than in real life.

 

Ps. Tried the search, but didn't find or I just didn't use correct keywords, as I couldn't find a topic where this was discussed.

Just fit standard ride height springs and shock absorbers.

With standard front suspension, make sure you are using 70mm rubber stops on the front shock absorbers, as the heavy duty front suspension used longer 90mm rubber stops. The 90mm ones are too long for the standard front suspension, and if you used them you would loose 20mm of front suspension travel. This should have been changed when the lowered front suspension was fitted.

Hi.

 

Thanks for the detailed answer . Back when I swapped the springs and shocks, I also fitted new stops front and back as well new spring front bearings so no rough road items would be mixed to lowered suspension. Stops and dust covers were actually made by Sachs (front: #900 105, back: #900 203) and were meant for "cars with sport suspensions" as autodoc advertised them. So they are probably the shorter version, or event the 55mm version as there seems to be that length also according to 7zap site? 🤷‍♂️

I didn't measure the actual height as I was not aware at the time that there were differencies in height.

 

I don't want swap shocks now as they have done only about 40k (kilometers) and are in good condition. About the springs, I don't know why, but I have always been under the impression that standard rear springs wouldn't be stiff enough for 4x4 model and would cause the rear to sag, because the added weight at the back from diff and other 4x4 parts? Or atleast it would sag harder with boot loaded up as I am a family man nowadays🤔

 

Autodoc also offers different part numbered Bilstein B3 springs front and back to three different dsg fitted models (the 3.6, 2.0 2wd diesel and 2.0 4wd diesel). So are they all a bit different height and stiffness after all? 🤔🤷‍♂️

 

On other note, does the "standard 3.6" has any lower rideheight as standard than say "standard 2wd" models? The factory sport suspension has probably been an option to choose on both, but not on the 4x4 diesel version if I remember correctly from other forum posts?

 

I know my thinking of this spring matter seems crazy to other people, but try to bear with me.

Sachs 900 105 and Sachs 900 203 are listed as sport, so are likely to have the 55mm front rubber buffers and the 118mm rear rubber buffers. The standard suspension uses 70mm front rubber buffers and 133mm rear rubber buffers, ie. 15mm higher/longer front and rear rubber buffers to match the 15mm increase in ride height.

 

When I write standard springs, that means the standard springs for your Superb MK2 2.0TDI 4x4 estate, not a different car such as a 2WD car or 3.6.

 

The 3.6, 2.0TDI 2 Wheel Drive, 2.0TDI 4x4, can all have standard springs, but they may be different and often will be different. Springs are closely matched to the weight of the car. Fit the wrong springs and you can end up with the wrong ride height and/or the wrong spring stiffness.

 

gknautomotive sell the same front spring for both the Superb MK2 2.0TDI 2WD estate and the Superb MK2 2.0TDI 4x4 estate, but they sell a slightly stiffer rear spring for the 4x4 compared to the 2WD version...because the rear of a 4x4 weighs more than a 2WD.

Thanks Calrston for this great info. For some reason I thought standard springs were only for 2wd model, but as there is a standard springs available for a 4x4 also, I will fit those. You learn something everyday it seems.
