Wheel on b5.5

With that high offset front wheel will foul inboard suspension .

Spaces required hubcentric with longer bolts plus at rear too , go extra 5mm at the back .

All assuming B8 have same PCD .

I've ET 47 7.5"J B6 wheels and offset perfection is achieved with 15mm front and 20mm rear spacers , so my suggestion to the OP is 20mm front and 25mm rear .
