16x8 Offset PLEASE HELP!!
 

I have a EJ8, lowered about 2 - 2.5", I am looking into getting new rims for her, but don't know the correct offset to get. I understand the basics of offset but can never measure it right. I want the lip to be flush or poking a little past my fender, I am going to run a pretty small tire so I'm not worried about that. If it helps any I am going to run about -5 degrees of camber on all corners
