I did some research on the internet, And found the offsets of:

17x8.5 = +58 MM
18x9.5 = +65 MM

I picked up my wheels today, and this is what I found...




Are these the wheel offsets?

A simple yes or no is all I need.

Also, To get my wheels "Flush" with these offsets, Do I need a Final ET of +20 Offset? I have heard this from a few people, I just want to confirm before I drop 400$ on wheel adapters.

Thanks!

 

To be flush I'd say a final offset in the ballpark of +20 up front and +30 outback

 

Thanks man, i'm going to order my adapters with a few extra MM to be safe, i can roll my fenders if need be.
