s13 rim offset?

[jdms13rhd]

I have a silvia and i dont know lots about rim offset. Im looking for a 17"x7.5 or 8 and i want to know what offset to get so my car dont look like shit. I dont want them to tuck in. Im looking for more of the drift style with a bit of a dish.
Can you help me out. I can only find +40 offset and i think that looks gay.

if you have 4 bolt then its hard to find wide wheels with the right offset.

8" or more you will need 35mm or less.
