S3 wheel upgrade

[Karbb1]

Hi, Im new and thanks for letting me join. I drive an S3 2014 8v which I've owned for 2 years, done a few mods over the last year and now looking to upgrade my wheels.
I like the Bola B1's but un sure of what offset to go.
Has anyone got any experience they would like to share. I currently have 18" factory wheels and was going to replace with 18" B1's but not sure of the offset.

i dont know anything about your rim set.
audi makes a lot of different versions.

what i do recommend is that you look up the spec online. another way is to take off one of the wheels and look in the back of the rim.
that will help give you the ET number.
