Here are three standard Fabia MK4 rim sizes.

A 8J rim is a bit wide for a 235/45R18 winter tyre, because there's not much rim protection from kerbing damage. Imagine driving in deep snow where you can't see the kerb. Even a gentle nudge could see the exposed alloy rim easily scraped. 225/50R17 is a non-standard tyre size on the Octavia MK4, but very popular on the Octavia MK3 Scout and Yeti...and could be a good alternative to the standard 205/55R17 tyre size on the Octavia MK4. The 10.1kg claimed weight of the below 17" alloy rim is considerably lighter than most 18" alloy rims. For comparison, the 18" COMET alloy rim on the Octavia MK4 is claimed to be a whopping 14.9kg...almost 50% heavier than the lightweight 17" rim. 7Jx17 ET45 5/112 57.1 alloy rim RATIKON (from Karoq) (claimed weight 10.1kg) https://eshop.skoda-auto.cz/cs_CZ/alu-kolo-ratikon-17-karoq/p/57A071497C+8Z8 7.5Jx18 ET48 5/112 57.1 alloy rim COMET (from Octavia MK4) (claimed weight 14.9kg) https://eshop.skoda-auto.cz/cs_CZ/alu-kolo-comet-18-octavia-iv/p/5E3071498C+8Z8 Another option on a 7Jx17 ET45 alloy rim, is 235/50R17. There's not much availability of winter rated tyres in this size, but there's Hankook's latest H750 all-season tyre. Compared to 225/50R17, 235/50R17 would provide a little more rim protection from kerbing damage.

You can see on the link below to "skoda eshop cz" that there are two different foam and jack kits for the Superb MK3. One for all models except the 272HP/280HP 4x4, and one for the 272HP/280HP. 2,149CZK is about £76.18 and includes everything except the actual spare wheel. Remember though, a spare wheel that has an actual width of more than 215mm will raise the carpet on the Superb MK3. Perhaps ask for a quote (using the OEM part number 3V0093860D) from a Skoda/VAG parts department. This might work out cheaper than purchasing one online. Make sure they confirm that this part is correct for your car, before making any purchase.

Secondhand calipers on ebay are about £25. I would strip it down, clean it up, perhaps fit a cheap rebuild kit, and hand it to the mechanic for fitting. However, you could just visually check it to make sure the rubber seals aren't damaged/split and take a chance that the piston slides in and out easily and doesn't leak.

You can get a good secondhand rear left or rear right brake caliper for about £25. You can get new Bosch rear 272x10mm brake discs for about £30 each, and a set of new Ferodo rear brake pads for about £25. Total parts cost about £80 plus shipping. Then perhaps about 1 hour's labour at about £85 including VAT. Let's say under £200 total cost including labour.

The spare tyre would have to be completely flat, or it would raise the carpet. Some Superb MK3 owners have already found a way to support the floor (by using 20mm thick packing material) so that they could use a 235/45R18 or 235/40R19 spare tyre. See the various previous threads on the subject, as the spare wheel for the Superb MK3 has already been covered extensively. If you are going to use a 215/55R17 fitted to a 7J rim, you would only need 10mm thick packing material.

Search for 3V0601025C and 3V0071497D if you are interested in those two rims. 8Z8 is the associated 3-digit colour code and means diamond silver. It's not necessary and usually not helpful to use the 3-digit colour code in the search. 3V0601025C and 3V0071497D is specific enough.

If you are using different tyre sizes on the same axle, then you need to treat it as a space saver, ie. limited to 50mph. Maybe you could store a 215/55R17 fitted to a 7Jx17 ET40 rim uninflated. I once stored a punctured tyre (ie. uninflated tyre) in the spare wheel well for over one year, and then got it repaired and it seemed ok. However, I doubt the tyre industry would recommend storing a spare wheel uninflated in the spare wheel well for a long period of time. I suspect storing a spare tyre in the spare wheel well that lifts the carpet could damage something if a heavy load was carried in the boot. I would much rather use a 215/60R16 and 215/55R17 on the same axle, than a 125/70R18 and 215/55R17. Although if I was using a skinny space saver on the Superb MK3, I would use a 135/80R18 rather than the Skoda supplied 125/70R18. This is because the outside diameter of a 125/70R18 is about 5% smaller than the standard tyre sizes on the Superb MK3, whereas the 135/80R18 is a close match to the outside diameter of the standard Superb MK3 tyre sizes.

Notice that the OEM part number for the below rim has a xxx601xxx format. This is different from the accessory catalogue, which uses a xxx071xxx format. The xxx601xxx format is a factory supplied rim. The rims from the accessory catalogue tend to be a lot cheaper to purchase new, than a factory replacement rim...even though they are sometimes the same rim, except for the OEM part number. Most secondhand rims listed for sale on ebay will have the factory format, as they will have originally been factory fitted to a new car. 7Jx17 ET40 5/112 57.1 alloy rim STRATOS (not from the accessory catalogue) 2 3V0601025C Aluminium rim 7Jx17 ET40 4 PR-C6U 3V0601025C 8Z8 Diamond silver STRATOS https://www.lllparts.co.uk/catalogs/skoda/CZ/SUP/851/6/601/601070

17" Stratos alloy rims for the Superb MK3 have a specification of 7Jx17 ET40 5/112 57.1 which you can see on the below link. https://eshop.skoda-auto.cz/cs_CZ/alu-kolo-stratos-17-superb-iii/p/3V0071497D+8Z8 If you are looking for a full size spare wheel, 215/55R17 fitted to a 7J rim won't fit flush in the spare wheel well without lifting the carpet. Perhaps look at 215/60R16 fitted to a 6Jx16 ET43 5/112 57.1 steel rim from the Karoq. This has an actual inflated width of about 215mm, which is about as wide as you can go without lifting the carpet. For comparison, a 215/55R17 fitted to a 7J rim has an actual inflated width of about 226mm. Notice that the "215" in 215/55R17 is just the nominal width. The actual inflated tyre width always depends on the rim width to which it is fitted. If you fitted a 215/55R17 to a 6.5J rim it would have an actual inflated width of about 220mm, and if you fitted a 215/55R17 to a 6J rim it would have an actual inflated width of about 214mm. Alcar 6665 6Jx16 ET43 5/112 57.1 steel rim (from Karoq) https://www.mytyres.co.uk/rims/details?vehicleId=1388704626380403824&rimCode=ALCAR6665 Bear in mind, that a 16" rim won't clear the 340x30mm front brake discs that are fitted on the powerful Superb MK3 272HP/280HP 4x4 cars. These cars need at least a 17" rim to fit on the front, although you could fit a 16" spare wheel on the rear and swap the 17"/18"/19" rear wheel to the front. Another option could be a 205/60R17 fitted to a 6.5Jx17 ET38 5/112 57.1 steel rim from the Kodiaq. A 205/60R17 fitted to a 6.5J rim has an actual inflated width of about 215mm. So again, this should fit in the spare wheel well without lifting the carpet. Bear in mind that the spare wheel well on the 4x4 models, might be smaller than the spare wheel well on the front wheel drive cars. So this point is worth checking if you have a 4x4.

Alcar 9490 6Jx16 ET40 5/112 57.1 steel rim (from Superb MK1) https://www.mytyres.co.uk/rims/details?vehicleId=180617324850582640&rimCode=ALCAR9490

The rear brakes on the Fabia MK1 VRS are a TRW brake system, so it makes sense to use TRW rear brake pads. These shouldn't be noisy as they will have had a lot of R&D. TRW GDB1330 rear brake pads (for Fabia MK1 VRS) https://www.autodoc.co.uk/trw/2191943

Try Bilstein B6 shock absorbers. You would have to use the standard ride height ones, but I doubt the extra 15mm of ride height would cause the Bilstein B6 shock absorbers any problems. This is because if you have ever jacked up your car to change a wheel, you will know that standard ride height shock absorbers extend quite a bit before the wheel lifts off the ground. Perhaps try changing the rear shock absorbers first. This is because they are cheaper than the front and the labour involved is a lot less than the front. If you are happy with the change, then go ahead and change the front. Another option is to use standard ride height springs with the Bilstein B6 shock absorbers. However, I think in keeping with the style of the Scout, keeping the increased ride height would be more appropriate. The Bilstein B6 shock absorbers should give the suspension excellent control, so I doubt you will need to lower the car to standard ride height. However, keep in mind Bilstein B6 shock absorbers combined with standard ride height springs if the shock absorbers on their own don't provide the desired effect. Many Superb MK3 owners aren't happy with the car's standard shock absorbers, so the Scout version with its 15mm increased ride height might simply make things worse.

There's three OEM part numbers shown in the Skoda parts catalogue for the left front brake caliper on the Fabia MK1 with 288x25mm front brakes. They are all the same except for the colour. The VRS model uses either green or red depending on the car's build code. Build code 1LP is green, and build code 1ZD is red. If you search for new or remanufactured green or red calipers, most brands simply supply the standard grey colour. On autodoc, there's no green ones shown in stock, but there are a couple of red ones shown in stock including remanufactured red TRW ones. However, autodoc does show some new grey TRW ones in stock. In the three links below, I've only shown the left front brake caliper. So check that a matching right front brake caliper is also available. The corresponding right front brake caliper has OEM part number 6Q0615124 (grey), 6Y0615124 (green), 6Q0615124A (red) respectively.

Audi made some lightweight forged alloy rims with a specification of 7Jx16 ET45 5/112 57.1 for the A4 (around the year 2000) that weighed only 7.3kg. So changing to those could offset the extra weight of 312x25mm discs. 7.3kg rims would probably save between 2kg to 3kg each rim compared to the standard Yeti 7Jx17 ET45 5/112 57.1 alloy rims. From the below chart, changing from 288x25mm to 312x25mm adds 1.3kg to the weight of each brake disc. The carrier is probably also a little heavier. Weight of each front brake disc (according to Brembo) 280x22mm 5.9kg 288x25mm 7.3kg 312x25mm 8.6kg With 7Jx16 ET45 rims, you could fit slightly oversize 225/60R16. This is one of the tyre sizes that the Karoq 4x4 uses. Compared to the standard 215/60R16 it only increases the gearing by 1.8% as shown in the chart below. Outside diameter of tyres 215/60R16 664.4mm 225/60R16 676.4mm (+1.8%) 225/60R16 has 20% more sidewall height than 225/50R17 as shown in the chart below. The improvement in ride comfort of the 20% higher sidewalled tyre should be quite noticeable.

EBC brakes on autodoc thinks that the Yeti 2.0TDI 150HP (2 or 4 wheel drive) uses 288x25mm front brakes. Most of the other brands on autodoc list more than one size for that engine version, which means that they either don't know or that more than one brake size was used. Out of the diesel engined Yetis, it's only the 105HP and 110HP versions that EBC lists as having the smallest 280x22mm front brakes.

The diagram of the ATE 11.0230-0131.1 shows that one of the spacing measurements is 146mm. What is the Mapco spacing and what is the spacing on the wheel bearing housing? If the ATE diagram is correct, the spacing should be 146mm on the wheel bearing housing.

What OEM part number were the carriers that you tried? What was the spacing of the bolt holes? OEM part number of front brake caliper carrier 1ZE 288x25mm 1K0615125D 1ZA 312x25mm 5N0615125 ATE front brake caliper carrier 312x25mm 1ZA 5N0615125

Build codes for front brakes 1ZA 312x25mm front brake discs 1ZE 288x25mm front brake discs 1ZF 280x22mm front brake discs Build code 1ZA and 1ZE use the same wheel bearing housings, as shown in the chart below. The front brake carriers bolt directly to the wheel bearing housings. So if the front brake carriers for the 312x25mm front brakes don't fit, it's because you have 280x22mm front brakes, ie. build code 1ZF.

There's no trace of engine code CRBL. Do you mean CRLB? Kilen list the same 5Q0411105GM front springs and 3Q0511115AK rear springs for the Superb MK3 2.0TDI 150HP estate. It probably best to find out what the car's build codes are, especially considering that there's an ebay seller who can supply them for about 3 Euros. Then you can find out what was factory fitted. The Sportline might have come with lowered suspension. "vin skoda decoder" https://www.ebay.co.uk/sch/i.html?_from=R40&_trksid=p4432023.m570.l1313&_nkw=skoda+vin+decoder&_sacat=0

It depends how badly you need the extra ground clearance. The 1.4 petrol turbo engine should have good low down torque, so maybe try it. First check if you current speedo is over-reading by almost 5%, ie. is 50mph on the speedo actually no more than 48mph?

What Octavia MK3 do you have? For example, Octavia MK3 2.0TDI, 150HP, estate, DSG, front wheel drive, no factory fitted towbar, etc. If you have front wheel drive, you won't be using Scout suspension because that is 4x4. You could fit 15mm increased ride height springs and shock absorbers. Perhaps you could first try oversize tyres. As long as you don't have bigger front brakes discs than 288x25mm you could try 205/70R15 on 6Jx16 ET43 5/112 57.1 steel rims. Compared to 225/40R18, 205/70R15 would raise the gearing by 4.8%. This is quite a big increase, but if you have a 2.0TDI the engine should have enough torque to cope. Just check that your speedo won't over-read by using GPS such as the one on google maps.

What model have you got? eg. Superb MK3 2.0TDI 150HP hatchback, DSG, standard ride height. no factory fitted towbar. For that car Kilen/Lesjofors are suggesting 5Q0411105GM front springs and 3Q0511115AK rear springs.

On the Superb MK3, Bilstein B6 non-DCC are a monotube design, whereas Bilstein B6 with DCC are a twintube design. Monotube is better than twintube, so it's a good job yours is not DCC. However, if you want Bilstein B6 you might have to search using a similar VW Passat B8 model as Bilstein haven't listed them for the Superb MK3. This might just be an oversight on Bilstein's part because those who have fitted Bilstein B6 to their Superb MK3 generally seem pleased with them.

If you want all your car's build codes, there's an ebay seller who can supply them for about 3 Euros. This is useful for many things, including being able to work out what brakes, springs, shock absorbers, etc. were fitted to the car in the factory.
