Apparently Cupra has original 19x8 ET50 CT57.1
19x8 ET40 is the lowest I would go in the front and ET38 in the back.
Therefore, keeping my same original tire profile of 235/35 R19 the OZ Ultraleggera 19x8 ET47 will fit perfect (can also go ET38 but that will poke a lot more), or the JR wheels with ET40.
Hope I'm right
