Does anyone know what the standard size is on these cars are? Mine could do with replacing but before I order some I wanted to make sure that I Purchase the correct ones. I have read some posts that mention 340 mm but I have also read comments referring to 370 mm so I just need clarification really. Thanks in advance.

The ones on my 2018 Cupra are 340x30mm ventilated at the front and 310x22mm solid at the rear. Edit - see below, my rears are vented too.

Bigger sizes mentioned are probably big brake kits (or the sub8 option).

When did they change the rears to ventilated? My MY19 has 310mm vented brakes at the back as stock.

Mines an October 2018 car (290), bit of a mixed bag as its a mix of parts from 18 and 19. One of the last cars with the silver badges but it has the 7 speed dsg and GPF.

To be honest I'd not actually checked if they are solid or vented. Just presumed from the spec sheet (which says solid online). Ive just had a look and they are in fact vented.

Can't beat a proper physical check.

Standard are 340 at the front.

The reason you sometimes hear/see 370 is due to some cars having the Sub8/Performance Pack brakes like these:
