Wheel Offsets??

Ok I need some advise from the gurus here, I have my eibach lowering springs on the way, however I am looking at two sets of wheels, but I think the offsets are too low on wheels. I know very little other what I have learned here.

The first set of wheels I am looking at are 18x8 with a 30mm offset. Using an offset calculator its tells me the wheel will stick out further by 15mm, the other set of wheels I am looking at is 18x8.5 with a 33mm offset, and an offset calculator is telling me that the wheels will stick out 18 mm more, then the stock. This sounds like it shouldn't rub, and my measurements seem to say they will be fine, however, I am not sure if I am missing something.

Will this cause rubbing with the eibachs??

If this is going to rub, what what is the offset range I should keep the wheels at with 8 or 8.5" wheels?
