theyre 18x7.5 ET50. Just another one of VW’s OEM 18x7.5 ET50 designs like Canyons, Austin’s, Dallas, Detroit’s, Serrons, etc etc etc lolThe ET is stamped to the inside of the wheel.
You could probably do the standard 15mm rear, 10mm front spacers.
Are those factory wheels?
They are 19x7.5 ET51, I would do 15mm front 20mm rear with longer bolts of course(M14x1.5 spherical).
