Hello

I have been trying to figure out what absorbers to upgrade my  Superb estate. As I have retrofitted 19 wheels i would like to improve comfort as i fell more  small holes.

My car come with PR codes 1JC and G02 witch i think are  5Q0513049FP or 5Q0513049FN for rear and  3Q0413031BG for front.

 

Bilstein B6 has been recommended here on the forum for 2.0 but does anyone recommend for 1.6TDI?

 

I think that bilstein parts are  24-011105 rear and 35-229872 for front although these partes on bilstein page are for opel omega but i thinks these are correct ones.

 

has anyone made this change on 1.6 TDI ?

Maybe the correct rear ones are 24-229890 I'm still not sure.

Really had a tough conversation with Bilstein about the 24-229890 because they have messed up the pr codes for this part witch by the way is the correct ones for the Superb 3.

They are advertising that the part is for cars with pr code G01, G02 etc  but it should say 1JC that is ment for the rear.

 

G02 - DFV Shock absorption in Front > all G0 are for the front

1JC - Rear shock absorption for sports version > all 1J are for rear

 

Lets see if after our conversation they correct .

As you have lowered ride height (ie. build codes G02, 1JC), have you considered Bilstein B8 24-229937 rear shock absorbers instead of Bilstein B6 24-229890 rear shock absorbers?

 

As you can see in the chart below, the B8 rear shock absorbers are only 20mm shorter than the B6 ones.

Sorry for the late response , had no notification that someone  responded to the thread. The sports shocks absorbers came from fabric witch is strange given that it's a 1.6 tdi with nothing sporty.

I still have not changed them so I might consider those ones to.

Your Superb MK3 1.6TDI estate has lowered ride height...which Skoda also calls sports suspension.

 

Lowered ride height means that the unladen ride height is about 15mm lower than standard ride height.

 

Going back to your first post, you have retrofitted 19" wheels...presumably 235/40R19 tyres and yet you want a comfortable ride. Fitting such low profile tyres, ie. tyres with only 94mm of sidewall height (235mm x 0.4 = 94mm) is not the way to get the best ride comfort. 16" and 17" tyres with their much bigger sidewalls are going to put the ride comfort in a different league compared to these hard riding 19" tyres.

 

For the standard ride height Superb MK3 1.6TDI estate Kilen/Lesjofors and gknautomotive.com list 5Q0411105GL front springs and 3Q0511115AK rear springs. Even if you have factory fitted lowered ride height shock absorbers, you could probably get away with fitting them without changing the shock absorbers...although if you do change the shock absorbers it makes sense to match them with standard ride height shock absorbers...which including the Bilstein B6.

 

Superb MK3 1.6TDI estate - standard ride height front springs that are sold to replace 5Q0411105GL include the following two springs (actually the same spring, made in the same factory in Sweden) but there are many other brands

Kilen/Lesjofors aren't listing any sports springs for the Superb MK3 1.6TDI estate, but gknautomotive.com are listing 5Q0411105HD front sports springs and 3Q0511115AB rear sports springs. Front springs on hatchback and estate versions of the same car are usually the same because the front axle weight is the same...however, gknautomotive.com are listing slightly stiffer 5Q0411105HE front sports springs for the Superb MK3 1.6TDI hatchback. Note that the actual springs fitted by Skoda in the factory will often be slightly different to what is shown in the various online spring catalogues...but there shouldn't be much difference, often only one weight range difference if there is a difference.

 

According to Sachs, the 5Q0411105GL standard ride height front springs have a wire diameter of 12mm and the 5Q0411105HD lowered ride height front springs have a wire diameter of 12.25mm...so are about 5% stiffer than the standard ride height springs.

 

According to Sachs, the 3Q0511115AK standard ride height rear springs have a wire diameter of 12.25mm and the 3Q0511115AB lowered ride height rear springs have a wire diameter of 13mm...so would be about 15% stiffer, but 3Q0511115AB also has a smaller number of coil turns so are about 20% stiffer. 20% is a lot, so changing to standard ride height springs would help soften the rear axle a lot.

 

Because 3Q0511115AK standard ride height rear springs are so much softer than 3Q0511115AB lowered ride height rear springs, you may prefer the slightly stiffer 3Q0511115AL rear springs...but these are still about 15% softer than the hard riding 3Q0511115AB rear sports springs. Bear in mind, that many Superb MK3 estate owners complain that their standard ride height rear springs feel a bit too soft...so these 3Q0511115AL standard ride height rear springs being about 5% stiffer (this is a small amount that you will only just notice) might feel just right, yet still much softer than the hard riding lowered ride height rear springs.

 

3Q0511115AL standard ride height rear springs (one weight range higher than 3Q0511115AK, which is about 5% stiffer)

Bilstein B6 shock absorbers are for standard ride height cars.

 

Bilstein B8 shock absorbers are for lower ride height cars (aka, sports suspension).

 

The Bilstein B8 shock absorbers are only 20mm shorter than the Bilstein B6, so the idea that cars need to have at least a 30mm to 40mm drop for Bilstein B8 to work is incorrect. This idea that you need at least a 30mm to 40mm drop has probably come about because Bilstein B8 shock absorbers are sometimes sold in a kit with Eibach lowering springs where there might sometimes be a 30mm to 40mm drop compared to standard ride height...but Bilstein don't primarily aim their Bilstein B8 shock absorbers at Eiback lowering springs for which there is a very limited market but the much bigger market of VAG lowered ride height cars, ie. about 15mm drop.
