Scout models use +15mm springs. Therefore you could use standard ride height shock absorbers, as +15mm isn't much for the standard shock absorbers to cope with. Or use original Skoda Scout shock absorbers.

OEM part number 1K0511115BH could be used instead of 5Q0511115H as they appear to be the same springs. 1K0511115BH is from the Octavia MK2, whereas 5Q0511115H is from the Octavia MK3. If you look on autodoc you will see that there is more choice for 1K0511115BH rear springs than 5Q0511115H rear springs. 1K0511115BH https://www.autodoc.co.uk/car-parts/oem/1k0511115bh?search=OEN+1K0511115BH KYB RA7103 1K0511115BH https://www.ebay.co.uk/itm/234261311747?epid=25029981017&hash=item368b0ff103:g:LkkAAOSwQPthe9Vv

These are standard rear springs for the Octavia MK2 Estate 2.0TDI. Kilen 63118 (OEM part number 1K0511115BG) https://www.ebay.co.uk/itm/323693514969?epid=248980682&hash=item4b5da310d9%3Ag%3AcUIAAOSww35cZE7X&LH_ItemCondition=1000

It depends what country you order the car in. In Finland, Czech and Gemany, the RS model comes with 18" wheels as standard.

Normal 4x4 springs should be enough lift to the rear. Manual or automatic transmission usually makes a small difference to the front springs. It doesn't affect the rear springs.

NAPA NCS1114 matches OEM part number 3C0411105C. If you have a manual gearbox, this part fits your car. The specification of NAPA NCS1114 is identical to KYB RH3559, so it was probably made by KYB and is simply rebranded to NAPA. Sports suspension or lowered suspension means that the suspension is 15mm lower than standard. Increased ride height suspension or heavy-duty suspension, means that the suspension is 15mm higher than standard. OEM part number 3C0411105C is for standard ride height suspension. Your front shock absorbers have OEM part number 3C0413031AS (as shown in your photo). This is a standard ride height shock absorber, so your car has standard ride height.

On the Octavia MK4, the 18" wheels have a specification of 225/45R18 fitted to 7.5Jx18 ET48 rims, and that includes the Scout which is 4x4. On the previous Octavia MK3, the Scout which is 4x4 used bigger outside diameter tyres than other cars in the range, eg. 225/50R17 instead of 225/45R17. 225/50R17 has a similar outside diameter to 205/55R17 (the 17" tyre size fitted to the Octavia MK4)...so you could say that all models in the Octavia MK4 range have been Scoutified...at least with reference to the outside diameter of their tyres. I imagine all models including 4x4 are fitted with similar tyres, ie. eco summer tyres for maximum mpg and lowest CO2 emissions. wheel-size.com https://www.wheel-size.com/size/skoda/octavia-scout/2021/

I bought what was supposed to be a matched pair of springs from autodoc. One weighed about twice as much as the other spring and was massively bigger. This is why it's important to know the specification of the springs that you are buying. I sent the springs back for a refund, but autodoc refused to refund the cost of shipping them back...saying that I hadn't paid the £3 or £4 extra for the free return service...even though they were in breach of contract for supplying me with incorrect goods. For this reason, I prefer to buy from ebay especially as it's often cheaper. On ebay, return shipping is paid for if incorrect goods are sent out.

Sachs 993 061 or sometimes listed as Sachs 993061 (ie. without the space) is sold to replace 3C0411105C. They are no better than KYB RH3559 that also matches 3C0411105C. On ebay, the virtually identical Sachs is about two-and-a-half times the price. It seems like a no-brainer to go for the KYB, or at least something much better value than the Sachs. KYB claim their spring/shocks, etc. are fitted to about 25% of new cars. Whatever the exact percentage, they are certainly very big players. Kilen 25068 is available on ebay for about £26 each, so again much better value than Sachs. I doubt Sachs actually make the springs. I've got some, and they are just plain black springs with a Sachs sticker that someone has stuck on. The Sachs sticker itself is all crinkled, and peels off very easily...and sticks back on very easily. This suggests that Sachs hasn't actually made this spring, as I would have thought they would have marked it more permanently if they had made it. The amount of rebranding in aftermarket parts in on a massive scale. So often the parts that are sold under different brand names seem the same...but there are differences sometimes. Just look how many brands are selling springs to replace 3C0411105C on autodoc. I'm counting 38 different brands. There certainly isn't anything like 38 different factories making this same specification of spring. What's happening, is that there's a lot of rebranding going on...although the springs are unlikely to have come out of just one factory. 38 different brands of 3C0411105C springs listed on autodoc (there's a lot of rebranding going on) https://www.autodoc.co.uk/car-parts/oem/3c0411105c?search=OEN+3C0411105C&supplier[0]=253&supplier[1]=85&supplier[2]=246&awc=12639_1641577297_083478a8bfdbfbc4389cbb77895f0485&supplier[3]=32 With KYB and Kilen/Lesjofors you are more likely to find that these firms have actually made their own springs. I bought some Kilen/Lesjofors springs, and they had manufacturers' codes laser etched onto them, not some dodgy sticker applied as some kind of afterthought.

KYB RH3559 are sold to replace 3C0411105C and are available on ebay for about £20 each. https://www.ebay.co.uk/itm/334250861618?hash=item4dd2e76432:g:d20AAOSwYJ1htI5g 3C0411105C Kilen 25068 Lesjofors 4095086 Kilen/Lesjofors are the same springs, made in the same factory in Sweden.

The one before it, as fitted to the Octavia MK2 RS, had engine code BWA. The next 2.0 litre RS petrol engine that was fitted to the Octavia MK3 was called a EA888-Gen3 engine. Comparing the CCZA and CHHB engines, the torque went from 280Nm to 350Nm...that a very big 25% increase in torque. Of course, with just front wheel drive, putting the power down when you've got 220PS of power and 350Nm of torque can sometimes be a problem.

If your car has build code L03, it will have front springs with OEM part number 3C0411105C. If your car has build code L04, it will have front springs with OEM part number 1K0411105BP. As you can see, knowing your car's build codes makes it easy to identify what springs you have (and shock absorbers, and brakes, and many other parts on your car). However, if you don't know your build codes, the following should help. If you have a 2009 Superb MK2 2.0TDI 140HP 2WD with manual gearbox and standard ride height (eg. not +15mm increased ride height, or -15mm lowered ride height) you will have front springs with OEM part number, or something similar. If you have a 2009 Superb MK2 2.0TDI 140HP 2WD with automatic DSG gearbox and standard ride height (eg. not +15mm increased ride height, or -15mm lowered ride height) you will have front springs with OEM part number 1K0411105BP, or something similar. You can see in the chart below, that a 3C0411105C front spring has 1 orange dot, 1 green dot, and 2 yellow dots...and a 1K0411105BP front spring has 1 red dot, 1 white dot, and 1 red dot or 2 orange dots and 1 white dot. № part code title note quantity data model information suspension shock absorber (spring cyl.) anti-roll bar front combi 1 3C0 411 105 A coil spring 1 paint mark 1 paint mark 2 paint marks orange green orange 2 PR-L01 (1) 3C0 411 105 B coil spring 1 paint mark 1 paint mark 2 paint marks orange green yellow 2 PR-L02 (1) 3C0 411 105 C coil spring 1 paint mark 1 paint mark 2 paint marks orange green yellow 2 PR-L03 (1) 1K0 411 105 BP coil spring 1 paint mark 1 paint mark 1 paint mark also marked with: 2 paint marks 1 paint mark red white red orange white 2 PR-L30,L04 (1) 1K0 411 105 DK coil spring 3 paint marks orange 2 PR-L31 https://skoda.7zap.com/en/cz/superb/sup/2009-632/4/411-411001/ Specification of front springs with OEM part number 3C0411105C Spring Design Coil spring with constant wire diameter Fitting Position Front Axle Wire Diameter 12.75 mm Length 339 mm Outer diameter 142 mm Weight 2.2 kg Transmission Type Manual Transmission https://web.tecalliance.net/gkn/en/parts/1/86458/detail?targetType=cars&targetId=31965&typeNumber=31965&groups=188#@brc/brands:Car;targetType:cars/assem:SKODA%20SUPERB%20II%20(3T4)%202.0%20TDI%2016V;targetType:cars;targetId:31965;typeNumber:31965/lnkparts:Coil%20Springs;targetType:cars;assemblyGroupId:100113;targetId:31965;typeNumber:31965;groups:188;brands:1;page:0/detail:86458;brandId:1;articleNo:86458;targetType:cars;targetId:31965;typeNumber:31965;groups:188 Specification of front springs with OEM part number 1K0411105BP Spring Design Coil spring with constant wire diameter Fitting Position Front Axle Colour Coding Orange (2x), White Wire Diameter 13.25 mm Length 342 mm Outer diameter 144 mm Weight 2.35 kg Transmission Type Automatic Transmission https://web.tecalliance.net/gkn/en/parts/1/56674/detail?targetType=cars&targetId=31965&typeNumber=31965&groups=188#@brc/brands:Car;targetType:cars/assem:SKODA%20SUPERB%20II%20(3T4)%202.0%20TDI%2016V;targetType:cars;targetId:31965;typeNumber:31965/lnkparts:Coil%20Springs;targetType:cars;assemblyGroupId:100113;targetId:31965;typeNumber:31965;groups:188;brands:1;page:0/detail:56674;brandId:1;articleNo:56674;targetType:cars;targetId:31965;typeNumber:31965;groups:188

5Q0511121BE is for a front wheel drive car, not a 4x4. You need to use 4x4 springs, if you have a 4x4. You can use 4x4 Scout springs if you want 15mm increased ride height, compared to standard ride height springs. The VRS 4x4 will probably have 15mm lowered ride height, ie. sports suspension. You have three choices of rear Scout springs. They will all give you about the same unladen ride height. The difference is in the compression rate. The 13.00mm version is about 8% stiffer than the 12.50mm version, and the 12.75mm version is about 4% stiffer than the 12.50mm version. As you are towing, I would go for either the 12.75mm or 13.00mm version.

Three spare wheel kits are shown on "skoda eshop cz" for the Octavia MK3, ie. standard version, Scout version, and VRS version. 1036CZK is about £35, so they aren't expensive new...and you should be able to order them from any Skoda dealer. The standard version should be able to take the standard full size wheels, including 195/65R15 fitted to a 6Jx16 ET43 rim, and a 205/55R16 fitted to a 6.5Jx16 ET46 rim. Although do check with the Skoda dealer before any purchase. https://eshop.skoda-auto.cz/cs_CZ/sady-pro-vymenu-kol/c/setsToChangeWheels?q=%3AscoreDesc%3AcarType%3AOctavia%2BIII%2B%282017%2B%29

Take a look at the engines on wikipedia to see which one you want. https://en.wikipedia.org/wiki/Škoda_Yeti For best fuel economy out of the petrol engines and no problems with DSG gearboxes, I would go for the 2015 onward 1.2 engine with engine code EA211 rather than the earlier EA111 and 6 speed manual gearbox. 16 valve engine, ie. 4 valves per cylinder. DOHC Double Over Head Camshaft. 111mph top speed, 0-62mph in 10.9secs. CO2 emissions 128g/km. 110PS@5,000rpm, 175Nm@1,500-4,000rpm. Fuel consumption 5.5/51.4/42.8 As maximum engine torque comes in from as low as 1,400rpm, it will drive better than even a 1.8 petrol engine without a turbo. These modern turbo engines give you lots of power low down in the rev range. The 0-62mph in just over 10secs and the top speed of over 110mph is plenty for this type of car. The top speed and acceleration is similar to some lower powered sports cars.

So go with... Front springs with 15mm increase in ride height 5Q0411105HN https://www.autodoc.co.uk/car-parts/oem/5q0411105hn?search=OEN+5Q0411105HN Kilen 23132 5Q0411105HN https://www.ebay.co.uk/itm/353523621748?epid=249508912&hash=item524fa65f74%3Ag%3A0nAAAOSw-S1guy8P&LH_ItemCondition=3 Rear springs with 15mm increase in ride height 5N0511115C https://www.autodoc.co.uk/car-parts/oem/5n0511115c?

Stick to the standard 205/55R16 tyre size for now. They are much cheaper than Scout sizes.

The main point is that the aftermarket spring manufacturers (and Skoda) supply stiffer front springs for the DSG automatic gearbox than the manual gearbox. You can check that for Optimal, Sachs, Spidan, and Suplex on autodoc. As you can see in the links below, the standard ride height front springs for the manual gearbox have a wire thickness of 11.5mm, and for the DSG gearbox it's 11.75mm.

The Octavia MK2 uses 5/112 hubs. The Audi TT MK1 uses 5/100 hubs. So the 334mm x 32mm 5/100 front brake discs won't fit. https://audi.7zap.com/en/rdw/audi+tt+tts+coupe+roadster/att/2006-278/6/615-615045/

According to "skoda eshop cz" there are two spare wheel kits. The first Yeti spare wheel kit 5L0071108B is for: 4WD Yetis 2WD Yetis made until 22/2010. https://eshop.skoda-auto.cz/cs_CZ/sada-pro-vymenu-rezervniho-kola/p/5L0071108B The second Yeti spare wheel kit 5L0071108C is for: 2WD Yetis made after 22/2010. https://eshop.skoda-auto.cz/cs_CZ/sada-pro-vymenu-rezervniho-kola/p/5L0071108C You should be able to order these at any Skoda dealer using the OEM part numbers given in bold type. A Skoda dealer should also be able to confirm whether it fits your vehicle.

Does your car have a manual or DSG automatic gearbox? The DSG automatic gearbox is significantly heavier than the manual gearbox. Therefore different front springs are used.

These springs should be about right for an Octavia MK3 1.5 petrol 150HP estate with 2WD to give a 15mm raised ride height. Compare the specifications on autodoc with the standard ride height springs. Stiffer springs won't compress as much, so you need to add about 3mm to the uncompressed spring length for every 0.25mm increase in wire diameter thickness. So if a replacement spring that is 9mm longer when uncompressed and has a 0.75mm increase in wire diameter thickness, will give an increase in unladen ride height of about 15mm. Front springs with 15mm increase in ride height 5Q0411105HN https://www.autodoc.co.uk/car-parts/oem/5q0411105hn?search=OEN+5Q0411105HN Kilen 23132 5Q0411105HN https://www.ebay.co.uk/itm/353523621748?epid=249508912&hash=item524fa65f74%3Ag%3A0nAAAOSw-S1guy8P&LH_ItemCondition=3 Rear springs with 15mm increase in ride height 5Q0511121BG https://www.autodoc.co.uk/car-parts/oem/5q0511121bg?search=OEN+5Q0511121BG Kilen 63541 5Q0511121BG https://www.ebay.co.uk/itm/393537924846?epid=4050207744&hash=item5ba0b02eee:g:aeYAAOSwxwhhKnZH Rear springs with 15mm increase in ride height 5N0511115C https://www.autodoc.co.uk/car-parts/oem/5n0511115c?

This makes the 5N0511115C version about 5% stiffer than the 5Q0511121BG version. I would use the softer 5Q0511121BG version rear springs with an Octavia MK3 1.5 petrol 150HP estate with DSG automatic gearbox, and the harder 5N0511115C version rear springs with an Octavia MK3 1.5 petrol 150HP estate with manual gearbox. The ride height should increase by about 20mm on the DSG automatic gearbox car, and about 25mm on the manual gearbox car. As the springs are now about 10% to 15% stiffer the effective ride height should increase by about 50mm when fitted with the bigger outside diameter tyres, as the suspension compresses less, ie. 20mm/25mm + 18mm + 7mm-12mm = 50mm. The standard ride height front bump stops are 70mm thickness. These need to be changed to 85mm if fitting 15mm raised ride height springs. You can see the OEM part number on the Skoda online parts catalogue. 85mm front shock absorber bump stop for 15mm raised ride height 5Q0412303 3 5Q0 412 303 rubber stop for shock absorber 85MM 2 https://skoda.7zap.com/en/cz/octavia/oct/2016-753/4/411-411002/ The rear suspension with 15mm increased ride height uses the the same thickness stop buffer as the standard ride height rear suspension. So unlike the front stop buffer, no change is needed on the rear when changing from standard ride height to 15mm increased ride height.

Scout springs will raise the ride height by a lot more than 15mm. If you go that route, you would need to match the Scout springs with Scout shock absorbers, usually only available from Skoda...as aftermarket ones tend to be for the far more common standard ride height suspension. Raised ride height and/or heavy duty suspension springs will give you a 15mm increase in ride height. You could use these with standard ride height shock absorbers. Compared to 205/55R16 tyres, 205/70R15 tyres (perhaps fitted to standard Octavia MK3 6Jx15 ET43 steel rims) would raise the ride height by 18.05mm. In combination with 15mm raised ride height springs, you would get a 33.05mm increase in ride height. To use 15" tyres, you would need to check that the diameter of the front brake discs is no more than 288mm. However, it looks likely they will fit the Octavia MK3 1.5 petrol 150HP because Jurid (a brand that sells brake parts) lists the 288mm front brake discs on autodoc as fitting this car. https://www.autodoc.co.uk/car-parts/brake-disc-10132/skoda/octavia/octavia-combi-5e5/128420-1-5-tsi?supplier[0]=48&criteria[100][1]=VA Uniroyal RainExpert 5 205/70R15 96H https://www.camskill.co.uk/m53b0s2481p208643/Uniroyal_Tyres_Car_Uniroyal_RainExpert_5_SUV_-_205_70_R15_96H_TL_Fuel_Eff_%3A_C_Wet_Grip%3A_A_NoiseClass%3A_B_Noise%3A_71dB There's lots of other tyres in this size, include Vredestein Quatrac 5 and AT (All-Terrain) tyres from Bridgestone, Yokohama, etc. https://www.camskill.co.uk/m53b0s2481p0/Car_Tyres_-_MPV_Tyres_-_People_Carrier_Tyres_-_15_inch_R15_inch_-_205_70_15_205_70R15 https://www.camskill.co.uk/m138b0s7998p0/All_Season_-_Four_Season_-_All_Weather_-_Car_MPV_Tyres_-_15_inch_R15_inch_-_205_70_15_205_70R15 The Octavia Mk3 1.5 petrol 150HP 2WD estate with standard ride height used these front springs or something similar, ie.

If you mean size 225/50R17, then Michelin CrossClimate 2 tyres are available in 98V, 94W, and 98Y as shown on the Michelin website. https://www.michelin.co.uk/auto/tyres/michelin-crossclimate-2?tyreSize=17 Blackcircles are listing all three versions. https://www.blackcircles.com/tyres/225-50-17?seasonal=allseason&manufacturer=michelin&delivery=1 The Michelin CrossClimate 2 is winter rated, ie. has the 3PMSF (Three Peak Mountain Snow Flake) symbol. That means that you are allowed to drop the speed rating if you want to. This is often shown in the owner's manual, but not always. You can also check with your insurance company whether they are happy for you to fit tyres that are limited to 150mph. Increasing the load index and/or the speed index will slightly increase the weight of the tyre and it's stiffness. If you did a back to back comparison, you might notice a slightly harder ride although the difference might be very small.
