The Born has 2x front brake versions:
PR: 1LA has 330x23 front discs
PR: 1LB has 340x27 front discs
They all have the same rear drum brake!.
Wheels are:
7,5JX18 ET50
7,5JX19 ET50
8JX20 ET50 or 7,5JX20 ET44
If a car has the bigger 340mm discs I can't see 5mm more on radius being enough to worry about a fitment issue?
The Leon Cupra has 340mm discs and 18" wheels as standard. And you can fit 370 discs under some 18" wheels.

Presumably the 340 disk is what is fitted to the e-boost variants ?
On my e-boost I can just get my index finger between the calipers and stock 19" wheels, so around 20mm clearance.
In theory, an 18inch wheel would leave something around 7mm.
I have no idea how much is consider safe, but its close enough that I would want to be certain before buying any !
Interesting you say ET50 on 18 and 19's, I though the 19 and 20's were both ET44 ?

Yep, you are correct
Still no idea if 18's will fit, the brake disks are only 10mm larger diameter, but I think the maybe calipers are bulkier too ?
Larger brakes can cause clearance issues. On my last VW, I replaced the original alloys with a set of genuine VW alloys from their accessories range. They were the correct size and fitment for my car but after the wheel balance weights had been fitted to the barrels of the wheels, there was only a few millimetres clearance between the balance weights and the front brake calipers. Similarly, there was very little space between the reverse side of the wheel spokes and the face of the front brake calipers.
So if 18’s will fit, there’s a fair chance that not all 18’s will; it may well depend on the design of the wheel.
@Vetku; most reputable online alloy wheel retailers‘ websites will have a vehicle look up facility so in theory, if you input details of your car’s make and model, it should take brake size into account when returning the search results. Therefore, you should only be shown alloys that will fit your car. Bear in mind that by fitting different alloys to an EV, if they’re heavier that the OEM wheels and / or if the tyres are less fuel efficient, then your car’s battery range is likely to be worse than it is with OEM wheels and tyres fitted to your car.
The 2x version of brakes are of 'similar' single piston sliding design just one is a little bigger. It's not like having a big Brembo caliper on there with 4x pistons.Yep, you are correct

I would be surprised if they didn't fit! but before spending money maybe a seat part dept can help? Do they sell winter wheels which fit all variants?
