Kilen and Lesjofors (same springs) list the following rear springs for the Superb MK2 170HP. As you can see below, the rear springs vary depending whether it's hatchback or estate, front wheel drive or 4x4, standard ride height or increased ride height. If the car has a factory fitted towbar, it may have left the factory with a reinforced (stiffer) version of the rear spring compared to a similar model that left the factory without a factory fitted towbar. Note that just because these rear springs are listed in the Kilen and Lesjofors spring catalogues, what the car left the factory with can sometimes be different. So cross reference the car's build codes with the Skoda parts catalogue, or find someone with ETKA who can let you know what rear springs the car left the factory with by cross referencing the car's VIN number with the ETKA database. The Skoda parts catalogue often lists the colour codes against the rear spring. So that's another way of finding out what rear springs are fitted. For example, the rear spring with build code 1K0511115BH has one white paint mark and two orange paint marks, as shown in the chart below. Rear spring 1JA 1K0511115BH One white paint mark Two orange paint marks 0YD There's a seller on ebay who can supply all of the car's build codes for 3.00 Euros (about £2.50). Search "skoda vin decoder" on ebay to find the listing.

Here are five rear springs that I would consider when looking for a spring that matches OEM part number 1K0511115CT. This includes the Bilstein 36-199570 that you linked to. As previously mentioned, 1K0511115CT and 5Q0511115AN are the same spring. The proof for this is Kilen 65073 and Lesjofors 4295087 which are sold to replace both 1K0511115CS and 5Q0511115AM...as shown in the link below. The benefit of choosing 1K0511115CT over 5Q0511115AN is availability and price. Kilen/Lesjofors suggests their 1K0511115CS/5Q0511115AM rear spring for the Octavia MK3 4x4 Scout...and 1K0511115CT or 5Q0511115AN is one up in the hierarchy which is about 5% stiffer. Some rear springs that match OEM part number 1K0511115CT Bilstein 36-199570 Eibach R10494 KYB RH6426 Lesjofors 4285730 Monroe SP4298 https://www.autodoc.co.uk/car-parts/oem/1k0511115ct?supplier[]=253&supplier[]=85&supplier[]=37&supplier[]=112&supplier[]=16 Kilen 65073 rear spring is sold to replace both 1K0511115CS and 5Q0511115AM https://www.autodoc.co.uk/kilen/7837926 Lesjofors 4295087 rear spring is sold to replace both 1K0511115CS and 5Q0511115AM https://www.autodoc.co.uk/lesjofors/9735347 Kilen 65073 and Lesjofors 4295087 is the same spring, made in the same factory in Sweden...just sold under two different brand names.

1T0413031JD is listed against Sachs 317 575 front shock absorbers, so if this is correct they should fit. 1T0413031JD is also listed against Bilstein B4 22-183729, so these front shock absorbers should also fit if the listing is correct. Sometimes listings have mistakes in them, so do bear that in mind when ordering.

dtintecno.de don't use the terms Stage 1, Stage 2, etc. Their remaps are for standard hardware. I expect dtintecno's 143kW/195PS 430Nm remap isn't quite as powerful as VAG's 140kW/190PS 400Nm tune because VAG is likely to be more conservative in their claims compared to the remapping companies. Perhaps think of dtintecno's remapping claims as the maximum power and torque that the engine will produce and VAG's claims as the minimum power and torque that the engine will produce.

G06 is shown on the white build code label, so the OEM part number for the front shock absorbers is 1T0413031JD. Although L61 is shown on the white build code label, the car doesn't also have build code G02...so the front shock absorbers don't have OEM part number 1K0413031BL. The Octavia MK2 2.0TDI 103kW/140PS 4x4 has 288x25mm front brakes with build code 1ZE. These are associated with front steering knuckles that use front shock absorbers with 55mm struts. 1K0413031BL are front shock absorbers with 50mm struts, so can't be correct for this car. L61 relates to the front springs and can be used with both 50mm and 55mm front struts.

According to dtintecno.de, the 2.0TDI 116PS engine remaps to the same power as the 2.0TDI 150PS engine, as shown below. Karoq 2.0TDI 85kW/116PS 300Nm engine remaps to 143kW/195PS 430Nm 2.0TDI 110kW/150PS 340Nm engine remaps to 143kW/195PS 430Nm 2.0TDI 140kW/190PS 400Nm engine remaps to 162kW/220PS 450Nm dtintecno.de https://www.dtintecno.de/

The Fabia MK2 1.4TDI engines weren't common rail, they were PD (Pumpe-Düse). According to the Fabia MK2 entry in Wikipedia, the only Fabia MK2 1.4TDI engine with DPF was the Greenline...so check the car's CO2 emissions. The 1.4TDI 80HP Greenline has CO2 emissions of around 109g/km whereas the non-Greenline version of the 1.4TDI 80HP has CO2 emissions of around 120g/km.

The Skoda accessory catalogue lists silver TRINITY alloy rims with the same 8Z8 colour code for both the Kodiaq MK1 and Karoq...as shown in the two links below. The Skoda parts catalogue describes colour code 8Z8 as Diamond Silver. As both alloy rims have the same 8Z8 colour code, they will both be the same colour. 7Jx18 ET43 5/112 57.1 TRINITY alloy rim 565071498D 8Z8 (from Kodiaq MK1) https://eshop.skoda-auto.cz/cs_CZ/alu-kolo-trinity-18-kodiaq/p/565071498D+8Z8 7Jx18 ET45 5/112 57.1 TRINITY alloy rim 57A071498 8Z8 (from Karoq) https://eshop.skoda-auto.cz/cs_CZ/alu-kolo-trinity-18-karoq/p/57A071498++8Z8

For non-standard 18" wheels on the Superb MK3, I would look at 225/50R18 fitted to 7Jx18 ET43 rims (from the Kodiaq MK1). The Kodiaq MK1 normally uses 235/55R18 on its 7Jx18 ET43 rims, but the outside diameter of these is too big for the Superb MK3. I wouldn't be looking at an offset more than ET43 with 225 tyres on the Superb MK3, unless you like your wheels to look sunken in the wheelarches.

The 15" wheels on the Fabia MK3 have a specification of 185/60R15 6Jx15 ET38 5/100 57.1 The outside diameter of the 185/60R15 tyres is far too small for the Scala, but you could use those rims with the 195/65R15 tyre size. The 195/65R15 is a winter tyre size on the Scala and is normally fitted to 6Jx15 ET35 5/100 57.1 steel rims. The ET38 rims from the Fabia MK3 will push the centre of each wheel 3mm further into the wheelarch compared to the ET35 offset.

The OEM part number of the nut is 6Q0407396B as shown in the Rapid parts catalogue. Going by a Febi listing for this nut on autodoc, it looks like it takes a 12-point (aka double hex) 36mm socket.

To get an idea of rim weights for the Superb MK4 you can look at the alloy rims shown in the Skoda accessory catalogue on "skoda eshop cz" for the Superb MK3 and Superb MK4. "skoda eshop cz" don't list the weights for all the alloys rims that they list. There's more alloy rims and their weights shown for the Superb MK3 compared to the Superb MK4. One point to note is that the 19" alloy rims listed for the Superb MK4 are quite a bit lighter than the 19" alloy rims shown for the Superb MK3. I expect all of these alloy rims are made from the same cheap, cast aluminium. Alloy rim weights for Superb MK3 16" 9.9kg 17" 11.25kg to 12.6kg 18" 12.1kg to 12.8kg 19" 13.9kg to 14.9kg Alloy rim weights for Superb MK4 16" 10.5kg 19" 12.6kg to 13.1kg Alloy rims shown on "skoda eshop cz" https://eshop.skoda-auto.cz/cs_CZ/alu-kola/c/alloyWheels?q=%3AscoreDesc For big weight savings, look at 16" steel rims such as the non-standard Alcar 6665 6Jx16 ET43 5/112 57.1 steel rim (from Karoq) (weight 7.60kg) and the non-standard Alcar 9187 6.5Jx16 ET43 5/112 57.1 (from Audi A3) (weight 7.62kg). These non-standard rims could be ideal for winter or all-season tyres...or even summer tyres for an owner who doesn't mind lots of sidewall height and lots of comfort. The Audi A3 steel rim is a similar design to the Karoq steel rim, so the Karoq wheel trims might also fit these Audi A3 steel rims.

16" wheels fit all Superb MK3 models, except the very powerful 2.0TSI 272HP/280HP 4x4 models...which need a minimum of 17" wheels due to their bigger brakes. The below link shows both 6.5Jx17 ET41 and 7Jx17 ET40 rims. For better comfort and better protection from kerbing damage it's best to go for the narrower 6.5J rims. My preference would be the Triton alloy rims, although the Markab alloy rims are also 6.5J. 17" Superb MK3 alloy rims (from the Skoda accessory catalogue) https://eshop.skoda-auto.cz/cs_CZ/alu-kola/c/alloyWheels?q=%3AscoreDesc%3ArimDiameter%3A17%22%3AcarType%3ASuperb%2BIII%2B%282015-2024%29&text=#

Below shows a standard 16" steel rim option for the Superb MK3 and a non-standard 17" steel rim option from the Kodiaq MK1. The 17" option works out quite a bit cheaper than the 16" option...at least going by the links below. The Kodiaq MK1 normally uses a 215/65R17 tyre size for its 17" rims, but the Superb MK3 uses a much smaller outside diameter 215/55R17 tyre size...so that would be the tyre size to use if considering 17" Kodiaq MK1 rims. The 17" Kodiaq MK1 rims use an ET38 offset, whereas the 16" and 17" Superb MK3 rims use either ET40 or ET41 offsets. However, having 2mm to 3mm less offset than standard isn't much and would move the centre of each tyre 2mm to 3mm further out in each wheelarch. The below wheel trims can be ordered from any VAG parts department by quoting the relevant OEM part number. The Czech price is about £69 to £72 for a set of four wheel trims. The big difference in ride quality will come from changing down from 235/45R18 to 215/55R17. Changing down further to 215/60R16 is a relatively small improvement over the 215/55R17. By changing from 235/45R18 to 215/55R17 I would estimate that you would get about three-quarters (75%) of the ride improvement compared to going from 235/45R18 to 215/60R16.

Before trying stiffer rear springs, it might be best to bring the rear suspension back to new condition...at least as far the the springs and spring seats are concerned. The estate will already have stiffer rear springs than the equivalent hatchback version...perhaps about 10% stiffer. Kilen/Lesjofors are made in Sweden in a modern factory so should be reliable. Kilen/Lesjofors are the biggest supplier of aftermarket car springs in Europe. Kilen and Lesjofors are the same, just sold under different brand names in order to increase market share. Just purchase whichever is cheapest. Kilen is usually cheaper and more common than Lesjofors in the UK, but in many European countries it's the other way around.

If you don't want to go down to 225/45R17, then slightly oversize 235/40R18 7.5Jx18 ET51 5/112 57.1 wheels should give a decent level of ride comfort. These tyres are 10mm wider than the standard 18" tyres, ie. 225/40R18. Notice in the chart below, that 235/40R18 would keep the gearing close to standard. 235/40R18 fitted to 7.5J rims would give much better ride comfort compared to 225/35R19 fitted to 7.5J rims. To get the 235/40R18 to feel as hard as the 225/35R19 you would have to overinflate the 235/40R18 by at least 6psi...and considering its easy to notice a 3psi difference, this is twice that difference. Outside diameter of tyre 225/35R19 640.1mm 235/40R18 645.2mm (0.8% bigger outside diameter compared to 225/35R19) 235/35R19 647.1mm (1.1% bigger outside diameter compared to 225/35R19) 225/40R19 662.6mm (3.5% bigger outside diameter compared to 225/35R19) 235/40R19 670.6mm (4.8% bigger outside diameter compared to 225/35R19) Alloy rims from the Skoda accessory catalogue can be ordered from any VAG parts department by quoting the relevant OEM part number. 18" alloy rims for the Octavia MK3 (from the Skoda accessory catalogue) https://eshop.skoda-auto.cz/cs_CZ/alu-kola/c/alloyWheels?q=%3AscoreDesc%3ArimDiameter%3A18%22%3AcarType%3AOctavia%2BIII%2B%282017%2B%29&text=#

Technical data The below information is an extract from the Superb MK3 owner's manual. As you can see there are only two tyre and rim combinations shown. Superb MK3 Permitted rim/tyre combinations for mounting of snow chains: Rim size Tyre size 6,5Jx16 ET41 215/60 R16 6,5Jx17 ET41 215/55 R17 Only fit snow chains with links and locks that are no larger than 13 mm.

The 215/60R16 tyre size doesn't need to be XL on the Superb MK3 because the standard load index of 95 (690kg) for this tyre size is more than enough. As you can see in the chart below, the 6Jx16 ET43 steel rim weighs 0.87kg less than the 6.5Jx16 ET41 steel rim. Weight of Alcar steel rims Alcar 6665 6Jx16 ET43 5/112 57.1 7.60kg Alcar 8426 6.5Jx16 ET41 5/112 57.1 8.47kg XL tyres aren't necessarily heavier than standard load tyres. For example, Michelin claims their CrossClimate 2 in sizes 215/55R17 94V and 215/55R17 98W XL both weigh 9.673kg each...as shown in the chart below.

If you search for a Karoq front wheel drive car, mytyres should let you select a 6Jx16 ET43 5/112 57.1 steel rim and a 215/60R16 tyre. An Alcar steel rim isn't shown, but an MWD steel rim is...when you search for a fitted tyre and rim combination for the Karoq front wheel drive. The Karoq 4x4 uses the same 16" rim but uses a slightly bigger 225/60R16 tyre size...so don't select a Karoq 4x4...unless you want a 225/60R16 tyre size. For some reason the Nokian Wetproof 1 215/60R16 99V XL (Euro label B A 69dB) tyre and steel rim is shown at an unusually low price of £115.14+£4.99 for shipping...and that appears to be for the tyre, rim, fitting, and shipping...although do confirm this yourself. Mytyres are selling this tyre and rim for about £140 excluding fitting and shipping, so it's surprising that the total fitted price including shipping is a lot less than this. It looks like mytyres has put the wrong photo of the steel rim on their website because the Karoq steel rim has 14 air holes for brake cooling...the photo of the MWD steel rim shows more than 14.

The skoda-parts.com website shows the following seven OEM part numbers for the 125/70R18 3.5Jx18 ET25.5 5/112 57.1 space saver spare wheel...which might help searching for one online. 57A601011A 57A601011B 57A601011E 5E0601011C 5E0601011D 5E3601011B 5E3601011L https://www.skoda-parts.com/spare-part/5e3601011l-spare-wheel-skoda-42126.html

From a quick google, it looks like 5Q0601027CJ has a 6J rim width, not a 6.5J rim width. 205/60R16 is not a standard Superb MK3 tyre size. It's outside diameter is smaller than the Superb MK3's standard tyre sizes, including the 235/45R18...as shown in the chart below. Perhaps use a 215/60R16 on a 6Jx16 ET43 5/112 57.1 steel rim (from Karoq) as a spare. This should fit in the spare wheel well without lifting the carpet. Outside diameter of tyre 235/45R18 668.7mm 205/60R16 652.4mm (2.4% smaller outside diameter compared to 235/45R18) 215/60R16 664.4mm (0.6% smaller outside diameter compared to 235/45R18) 205/65R16 672.9mm (0.6% bigger outside diameter compared to 235/45R18) An alternative suggestion for a spare wheel on the Superb MK3 is 205/65R16 on the standard 6.5Jx16 ET41 5/112 57.1 rim specification. Again, this should fit in the spare wheel well without raising the carpet.

On the Superb MK3, the 6Jx16 ET43 5/112 57.1 steel rim from the Karoq could be used as a spare. The advantage of using this slightly narrower rim is that it should fit in the spare wheel well without lifting the carpet...which is a problem with the standard Superb MK3 wheel sizes. As you can see in the chart below, the actual inflated width of a 215/60R16 fitted to a 6J rim is about 6mm narrower than when fitted to a wider 6.5J rim. If you need a matching steel rim for the other three that are on the car, then this alternative size won't be suitable...because all four rims on the car should have the same width and offset. Wheel trims from 6Jx16 ET48 5/112 57.1 steel rims on the Octavia MK3 might fit the Karoq steel rims...but you would need to check. I've shown these because I prefer the appearance to the 16" Karoq wheel trims.

As you can see in the chart below the 205/55R16 has an outside diameter 4.9% smaller than the standard 215/60R16 tyre size...so 205/55R16 is too small. The 6.5Jx16 ET46 5/112 57.1 rim specification could be used with the 215/60R16 tyre size. Someone has already done this on their Karoq front wheel drive car, as shown in the link below. Outside diameter of tyre 215/60R16 664.4mm 205/55R16 631.9mm (4.9% smaller outside diameter compared to 215/60R16) See this thread where one Karoq owner used 6.5Jx16 ET46 5/112 57.1 rims with 215/60R16 tyres. Compared to the standard 16" Karoq rim (6.5Jx16 ET43 5/112 57.1), this rim is 0.5" wider and has 3mm more offset. The 3mm increase in offset moves the center of the rim/tyre 3mm inwards into the wheelarch...which is quite a small amount so while driving the car you might not notice any difference. Karoq with 215/60R16 tyres fitted to 6.5Jx16 ET46 5/112 57.1 rims (ie. non-standard rims)

Here are some 17" alloy rims shown in the Skoda accessory catalogue. It's a Czech website, but you can order any of the alloy rims shown in the Skoda accessory catalogue from any VAG parts department...by quoting the relevant OEM part number. The slightly narrower 6.5J rims would give slightly more comfort than the slightly wider 7J rims, when fitted with the standard 215/55R17 tyre size. Other options for comfort include 16" rims and suitable tyres...but I suspect most Superb MK3 owners would find the comfort from a 17" tyre and rim combination good enough.
