I expect the following parts from the Audi A1 MK2 will fit, so you would have 312x25mm front brake discs. However, when you do these kinds of modifications there's always room for some unexpected problems especially if no one else has done this particular modification before.

 

If you already have 276x24mm front brake discs instead of the smaller 256x22mm front brake discs you will already have "2Q0407621A Wheelhub with bearing" which you should be able to re-use.

 

The parts are the same from the VW Polo MK6 GTI except for the "2Q0407621A Wheelhub with bearing" and the "2Q0615301J Brake disc 312X25" being different. If you use the VW Polo MK6 GTI version of these parts you will increase the front track by about 9mm. I suggest you use the Audi A1 parts which should keep the front track standard.

Hi Carlston

 

i want to do this upgrade too. I got complete wheel bearing houses with all the things you mentioned in your post. So from an accident Polo AW GTI. 
Possible to plug and play?

Btw, does anybody know how it is with rear brakes? I have already disk brake on my 1.5 TSI Scala. Need to change rear axle then?

The master cylinder (23.8mm piston bore) is the same on the Polo MK6 with both 276x24mm and 312x25mm front brake discs, and the Scala with 276x24mm front brake discs. The reason for the master cylinder being the same for both front brake disc sizes might have something to do with the front brake calipers both having pistons that have the same 57mm diameter. By comparison, the 256x22mm front brake discs use front brake calipers with 54mm pistons and a master cylinder with a 22.2mm piston bore.

 

On the Polo MK6, the 276x24mm front brake discs are normally matched to 230x9mm rear brake discs, whereas the 312x25mm front brake discs are normally matched to 272x10mm rear brake discs.

 

Both the 230x9mm and 272x10mm rear brake discs normally use calipers with 38mm diameter pistons.

 

Perhaps fit the 312x25mm front brake discs and see how you get on with the 230x9mm rear brake discs. If you don't normally carry much weight in the back over the rear axle you might be fine with the smaller rear brakes.

 

Weight of Polo MK6 front brake discs

276x24mm 6.5kg

312x25mm 8.3kg (28% heavier than 276x24mm front brake discs)

 

Weight of Polo MK6 rear brake discs

230x9mm 2.6kg

272x10mm 3.7kg (42% heavier than 230x9mm rear brake discs)

Thanks for the detailed answer. 
my rear brakes are completely down after 50K kilometers. Disks and pads. And front brakes i can ride another 30K.

Think it’s because of my setup:

Additional 60-70 kg in trunk due to 5kW Soundsystem. 2 Subwoofers, 2 amplifiers, additional Battery, lot of Bitumen. It’s like always having a passenger ob the Back row. You can see it on The wheel housing, it’s 1.5 cm lower than front. So all in all my car is about 100kg heavier than usual.

My Scala has about 240bhp. Stage 2.

 

So my question was if the holes on the rear axle will fit for the bigger caliper housing. The part numbers don’t match with the Polo‘s. I would need index CN but have BQ CE CG.

@SteffLimitless  Is there any possibility of you doing a Build thread in the Project section?

 

There have been many asking in the past years on remapping 1.5 TSI ACT,s to stage 1.  This is the first i have seen where someone has one with Stage 2.

I totally not recommend Stage 2. It was more than 10K Swiss Franc. Parts are from different bigger VAG cars. Everything is modified. The problem i have is the DQ200 now. Better to change whole Engine (2 Liter) with at least DQ250 transmission.

It will be more cheap.

so in the end i regret it.

for the remapping, you need a professional who does not just use files.

 

@thomasaspin  Has a Build Project thread you might want to read covering that with a Mk2 Fabia vRS.

The 15mm lower rear unladen ride height should be easy to fix.

 

If you have build code 1JA for the rear suspension, you might have 2Q0511121DM or 2Q0511121DN rear springs. If so, a change to 2Q0511121DS rear springs such as Sachs 992227 (matching 2Q0511121DS) should increase the unladen ride height by about 11mm...maybe even the 15mm you are after.

 

Note, that although the uncompressed length of the below Sachs 992227 rear springs are only 2mm longer, because the wire diameter is 0.75mm thicker these rear springs won't compress as much under load. Hence, you should get at least an 11mm increase in unladen ride height compared to the 2Q0511121DN rear springs.

Sachs 992227 rear springs (sold to replace 2Q0511121DS)

Length 320mm

Wire diameter 11.25mm

 

Sachs also sell Sachs 992226 which matches 2Q0511121DR, but these are 4mm shorter than Sachs 992227 so won't increase the unladen rear ride height as much.

Thanks Carlston

Unfortunately i ride lowering springs 45/40. Don’t wanted to lose the SCC function. So maybe i will ride 45/30 in future. The main thing is, i need better brakes on the rear too, because of the added weight. 
I noticed first from braking 230 to 130 that the stock brakes aren’t good. Hello German Autobahn.

That‘s why i plan to upgrade at least front brakes.

Do you already know if the 272mm brakes on the rear fit to the 230mm axle?

What is the OEM part number of your current rear axle?

 

I suspect it is 2Q0501053BQ which is also used on the Polo MK6 with 230x9mm rear disc brakes.

 

If it is 2Q0501053BQ, I suspect you will need a rear axle from the Polo MK6 with OEM part number 2Q0501053BF.

 

Perhaps purchase a complete rear axle/rear hubs/rear 272x10mm brakes setup from a Polo MK6 GTI 200HP/207HP.

 

At least if you do currently have rear axle 2Q0501053BQ, you will know that it is shared with the Polo MK6 so the Polo MK6 GTI rear axle should fit.

I got confused now. When i search the web for BF index, it shows without brake disk for 1.0 machine. Is it multi usable rear axle?

In the VW Polo MK6 parts catalogue, the only OEM part numbers shown for rear axles with drum brakes are 2Q0501053BP and 2Q0501053BS.

 

2Q0501053BF is the rear axle listed for build code 1KE (alongside build code 0N2), which are the big 272x10mm rear disc brakes.

 

However, if you find a secondhand axle from a scrapped Polo MK6 GTI, simply ask for the car's VIN number so that you can check that axle's OEM part number...if the seller doesn't know it. The OEM part number should be marked on the axle somewhere, so the seller should be able to find it.

If you get the VIN number of the Polo MK6 GTI that the axle comes from, you can get a list of the car's build codes from a seller on ebay for about 3 Euros. Search "skoda vin decoder" on ebay to find the listing.

Hello. Have you got front set from Audi A1 or VW Polo as mentioned earlier?

SteffLimitless said on 8th May 2024 that he has this (shown in the photo) from a Polo MK6 GTI, ie. 312x25mm front brakes and the associated parts.

 

Edited 15 May, 20242 yr by Carlston

This is from Polo

@SteffLimitless Have you looked at the Racingline big break kit?

 

https://www.racingline.com/performance-brake-kit-polo-gti-aw

 

If you scroll down the page, in the 'Confirmed Applications' list, the Scala 2019+ is listed.

I have many parts from Racingline in my Scala and the quality is second to none.

@Steve8O Thanks for the info. But here in Switzerland it’s too expensive to get this brakes legalized. So better use VAG brakes an nobody will notice. (Hopefully). 
 

@Carlston Does it need a coding for bigger brakes? My friend who leads a coding company meant the ABS Unit has to be flashed with Polo SVM.

I'm no electronics expert, but if you were to just change the front brakes there wouldn't be another VAG model (current Polo MK6 generation) with the 312x25mm front and 230x9mm rear combination.

@Carlston Just read on LLL Parts that my wheel hub Bearing should fit. In case the ones from Polo is too wide. 9mm axle or each side? Anyway, I have PR 1ZE brakes with Wheelhub Bearing 2Q0407621A .

The VAG parts catalogue lists 2Q0407621A for the Scala front hub bearings whereas it's 2Q0407621B for the Polo MK6 GTI.

 

On autodoc, there are plenty of the 2Q0407621A front hub bearings but only two listed for the 2Q0407621B front hub bearings...and those two are out of stock.

 

The Audi A1 is listing the 2Q0407621A front hub bearings for its 312x25mm front brake models, not the 2Q0407621B that the GTI uses...so the 2Q0407621A can be used with the 312x25mm front brakes.

2Q0407621A wheel bearings should fit the 2Q0407255L and 2Q0407256L wheel bearing housings because that's what the Audi A1 uses with its 312x25mm front brakes.
