As I changed the brakes of my VRS 288 to 300mm, what do I need to put these discs and calipers on our 1.2/12v HTP?

I think you mean 310mm/312mm rather than 300mm.

The 288mm front brakes use separate brake caliper carriers, whereas the smaller 256mm front brakes use brake caliper carriers that are built into the wheel bearing housing.

Therefore, when upgrading from 256mm to 288mm front brakes, the wheel bearing housing needs to be changed...as well as the front brake discs, front brake calipers, and front brake caliper carriers.

The Fabia MK2 models that came with the 288mm front brakes that have at least 105PS. So lowered powered models have the smaller 256mm front brakes.

The OEM part numbers can be obtained from a Fabia MK2 parts diagram, such as lllparts.

However, the brake system (and build code) was changed for the 2011 model year and onwards for the Fabia MK2. So up to and including the 2010 model year the Fabia MK2 has build code 1LN for its 288mm front brakes...and from the 2011 model year the build code for the 288mm front brakes became 1ZC or 1ZD. 1ZC and 1ZD are the same except for the colour of the front brake calipers/carriers. 1ZD is painted red. 1ZC/1ZD is an ATE brake system.

According to wikipedia, the Fabia MK2 1.4TSI VRS came out in 2010 (the 2011 model year) and therefore would have the 1ZD 288mm front brakes.

I haven't added the 1ZC/1ZD OEM part numbers below, but I the below OEM part numbers for the 288mm front brake discs and wheel bearing housings would also fit the 1ZC/1ZD 288mm front brakes.

Thank you, a lot of info that my old brain has to work with.

Yes it was a kit I bought for the F2 VRS, from www.4yourdrive.de with 310mm discs, calipers and pads. So I I thought to mount the 288mm discs/calipers on the 1.2/12V. So I only need to buy a pair off steering knuckles/wheel bearing housings to mount on the 1.2.

And the cover plates for the discs.

The 6R0615311 OEM part number that the Fabia MK2 1.4TSI VRS uses for the "left cover plate for 288mm front brake disc", is also listed against the early 256mm front brakes...so "cover plates for 256mm front brake discs" will sometimes (or maybe always) fit the 288mm front brake discs.

The below 275mm outside diameter backing plate is sold to replace 6R0615311 and two other OEM part numbers. 6R0615311 is the only OEM part number listed for the Fabia MK2 1.4TSI VRS front brakes, ie. build code 1ZD.

The below 313mm outside diameter backing plate is sold to replace 6R0615311D and no other OEM part numbers, so should be an exact match.

This demonstrates that the cover plates for the 288mm front brake discs don't always have a bigger outside diameter than the cover plates used for the 256mm front brake discs.

Out of the two below left cover plates, I would probably go for the bigger outside diameter 6R0615311D cover plate because that was the later model, ie. fitted to the the Fabia MK2 cars with 288mm front brakes and build code 1ZC from build date 26.05.2014.
