IIRC you need 38mm caliper clearance for the Cupra R Brembos and the standard Cupra alloys give ~26mm so unless you want to run silly spacers it's not happening.
The HiSpec R114-4 (4 pot) calipers fit under standard Cupra alloys and come as a 2-piece disc kit (310x28mm) so that gives you another option. I've got these fitted on mine.
