Hi, guys I'm from 318ti. org

I just got 1999 Audi A4 2.8 Avant quattro wagon.
now just looking for rims but I really don't know about right offset for my car.

Just need you guys help.
I don't want to get rub on the suspension or fenders.

18 x7.5 offset 35 or 45?
18x 8.0 offset 35 or 45?

will drop 3" soon
Thanks
