WRX wagon what max wheel offset
 

I wonder what is the maximum offset of the wheels that can be put on wrx wagon and don't rub stock rear fenders.
I know this depends on many factors, I am interested in your experiences. Please provide your setup and spec of wheels that fit or didn't fit your wagon.
From my experience, apart from stock wrx wheels:

FIT:
- 17x7 et 48 + 225/45 - fit with no problem, some room left;

DONT'T FIT:
- 17x7,5 et 35 + 225/45- they looked great, but it was a bit too much; they cut my tires a bit during corners and under load;

From these experiences it seems that offset of 40-45 on 7-7,5 rim and 225 tire seem to be the top.
