318ti rear with 15x7 et 20 or et0?

Ive just looked through the whole 5 lug thread and it seems like a bunch of skatterd BS. Havent found anything by searching either.
Anyways. got a late model with 318ti rear setup and e36 front.
Looking at a set of wheels 15x7 et0 or 15x7 et20. what ones would fit better? Meaning a decent size tire like a 205/50/15

Was recently in the same boat. ET0 will poke between 5-10mm all around.

I went with et20 and im just gonna play with spacers to get the fitment I wanted.

So your running a 15x7 et20 on 318ti rear? Just adding spacers to fit?
