Depending how much firmer you want your rear end, you might want to go up one, two, or three weight ranges. I wouldn't go up four...seems a bit much!

 

This post is for the benefit of Skoda Superb MK2 owners with a standard chassis looking for firmer rear springs. It isn't about MAD springs.

The MAD springs are a valid option for people who may not want the expense of a whole new set of components. You have added nothing useful to this thread, only filling it with links to parts and part numbers I had already included in the OP.

Just so I am not mistaken 

 

 

If i understood it right according to chiameras pdf , i would need the 3C0 511 115 AG and the 3C0 513 049 BR .

to go up 2 weight classes ?  To weight class 8.

 

If so I will order this

I've spotted another error in Chimera's pdf document.

 

1K0511115BL is similar to a weight range 6 (standard chassis) spring not weight range 10.

 

It could be that 3C0511115BL was meant instead of 1K0511115BL as 3C0511115BL looks like it might be a weight range 10 (standard chassis) spring.

1K0 511 115 BL is what's in the part catalogue for that weight range. If you think it's wrong, take it up with Skoda.

I'm guessing you think there's a pattern in part number assignment that's somehow been broken here. If so, a dangerous assumption. This rear axle is shared across a large number of brands and models and generations of models and a lot of different spring and damper specs will have been specified as a result. This leaves a lot of latitude for a suspension engineer getting to work on a new variant.

 

The Superb 2 uses springs that were originally specified for the Golf Mk 5 (1K), launched in 2004, and the Passat Mk 6 (launched in 2005). The Superb 2 was launched in 2008 so engineers starting work on it would have had a lot of choice in springs and dampers to get the setup they wanted.

The spring is correct. Your car is a facelifted model though, so the correct damper is 3C0 513 049 CP. If I remember correctly, the BR part was superseded in production by the CP part, so even if you went into the dealer looking for the BR part I think you would probably be given the CP one.

Hi chimaera 

Thank you very much for your help . I thought that mine was before the facelift . ( there you see how little I know about these numbers )

Here are the specifications of the weight range 6 to weight range 10 rear springs for the Skoda Superb MK2 (standard chassis):

 

1K0511115DF (Weight Range 6)

• Length [mm]:359
• Thickness [mm]:12,50
• Diameter [mm]:119

• Weight [kg]:2,45

3C0511115AF (Weight Range 7)

• Length [mm]:358
• Thickness [mm]:12,75
• Diameter [mm]:118

• Weight [kg]:2,45

3C0511115AG (Weight Range8)

• Length [mm]:362
• Thickness [mm]:13,00
• Diameter [mm]:118

• Weight [kg]:2,55

3C0511115AH (Weight Range 9)

• Length [mm]:364
• Thickness [mm]:13,00
• Diameter [mm]:116

• Weight [kg]:2,60

1K0511115BL (Weight Range 10) (Incorrect...looks like a weight range 6 rear spring)

• Length [mm]:365
• Thickness [mm]:12,50
• Diameter [mm]:115

• Weight [kg]:2,40

As you can see, the above weight range 6 spring has a thickness of 12.50mm, weight range 7 12.75mm, weight range 8 13.00mm, weight range 9 13.00mm, and weight range 10 12.50mm. So Skoda are claiming that their weight range 10 rear spring has the same thickness as their weight range 6 rear spring, which is of course incorrect.

As was pointed out back up the thread, it's not just the spring that matters here, the damper plays its part too. Also, you have no information on the metallurgy of the spring materials, or what the spring constant of any of them is. That said, maybe it's wrong but you will need to put that to Skoda as to why their parts catalogue is wrong. In the absence of any other reliable information the most robust choice is to stick with the parts catalogue.

The OEM part number 1K0511115BL is listed as suitable for most variants of the VW Golf MK6 3-door hatchback. It is clearly a lightweight spring. You can see that here on the gknautomotive.com website. Just click on the VW vehicle linkage to see the VW Golf MK6 3-door hatchbacks listed.

The standard chassis variants of the Skoda Superb MK2 use the same type of shock absorbers. They don't turn a light-weight range 6 rear spring into a heavy-weight range 10 rear spring.

So while getting an oil filter at Autosales Skoda i whipped out my measuring tape

 

 

ground to inside wheel arch

a Superb on low profiles  ......  27"

a fairly standard superb...........28"

My 2013 GL................................26"

 

but i had a full tank of fuel and some funny looks from the sales staff

 

 

seems my coils are

Ground to wheelarch is the wrong measurement. This has been pointed out several times on this thread and all the other ones you've posted about this on. The distance from the ground to the arch is affected by tyre pressure and condition as well as the suspension, and is therefore unreliable. The correct measurement is the top of the wheelarch to the centre of the wheel.

 

It has also been pointed out to you so many times by now that your car is, absolutely, without any possible doubt, sitting lower than it should be and you've been given lots of good advice on how to sort it out. Please sort it out instead of posting about it every few months in the hopes that some kind of magic solution has turned up in the meantime.

high is high, low is low whichever way you measure it, the centre-arch measurement is easy to get wrong, the total height is difficult to get wrong

The total height is easy to get wrong when a tyre half a bar under pressure can drop the car by 10 mm, and the difference between a new tyre and one down to the wear bars could be 9 mm, meaning a car on soft, old tyres could be 19 mm lower (using that measurement) than the same car on new, correctly inflated tyres, and might lead someone to incorrectly assume there is a problem with the suspension.

 

Centre to wheelarch is not affected by tyre pressure or tread depth, which is why that measurement is specified by the manufacturer for this purpose. It gives a true reading of the condition of the suspension.

why would i not check my tyre pressures?...

 thanks for the interest though

The point is there are too many variables involved if you measure off the ground. But I've pretty much given up on you seeing sense here, I'm posting for the people who find this thread in the future and who might be wondering about how to do this properly.

Where can I buy tyres that have 10.6mm of tread depth?

 

I currently have a buyer wanting money back one week after buying my last car because the rear tyres have 5mm of tread and he has a puncture on one which he says is not a puncture as its obvious that the rubber has worn so thin the tyre is deflating. 🥴

 

He also doesn't like the ride height of the uprated rear springs, declared in the ad, that he wanted for towing, the height he saw multiple times during the 2 hour inspection (after I had driven it 600kms to deliver it to him returning by TGV) because his trailer drawbar is lower & he doesn't want to use a drop plate as was clearly visible in the photos.

gknautomotive.com recommends 1K0511115DE rear springs for the Skoda Superb MK2 estate 1.6TDI

 

1K0511115BS is 32mm shorter than 1K0511115DE. 1K0511115BS is 11.75mm coil spring thickness and 1K0511115DE is 12.25mm coil spring thickness.

You should try and keep your posts in one place. In your other thread you've added a picture with paint codes that appear to tally with 1K0 511 115 BS.

 

@Carlston - you suggested BS in his other thread, which I'd agree with assuming the springs/paint codes are original

I thought it might be a Greenline as 1K0511115BS appear to be sports springs, and Greenline's tend to use sports springs to improve the drag coefficient by lowering the ride height.

 

It might be worth checking the car's build codes to see what was fitted in the factory.

 

If one of the car's build codes is PR-0YC then that means that the car was built with 1K0511115BS rear springs in the factory.

They each do plenty miles, being a GreenLine might well make little difference with some types of use.

Were they used as Taxis before you got them?
