What's ET AND J for BMW F32. Help me!

Hello! Gentlemen and ladies will be with me for days BMW F32.
I'm in the process of ordering rims.
The choice fell on 20 inches.
The car will be suspended by ISC
Does anyone know how many inches go to the front and back?
And what is the situation with et? I mean more about the front. I wish they were also concave inside. It is known that we will not make such a concave as it is, but that it sounds nice with the back, not the concave back, and the front zero ...
Can anyone help?

ET is offset and J is the width i.e 8.5j et30 is an 8.5 with a 30mm offset.

Not sure about your other questions but you typically need a wider wheel and/or lower offset for concavity (9” wide +)

Need to know the wheel width to provide feedback on offset
