iownme, the 215/45R18's will fit on your car with no problems from what I can tell. Even if you look at worst case, you are looking at a tire that is just slightly bigger than what is factory (0.7" in diameter). This will result in an error of 3% (so, when you are indicating 60 mph, you are actually doing 61.8 MPH). Not that big of a deal. This will not affect the car. Worst case, you will notice that the car will shift a little bit oddly when in a hilly area.
As for clearance, they will fit no problems as long as the offset is correct. You get that right and you will be in.
As for the rims that you are listing in your second posting, I would avoid those. those are RWD rim from what I can tell. Best case, you can put them on, but you are going to have some serious rubbing issues. You are going to be rubbing the tops of the wheel wells and the backs of the front wheel wells. All the additional rim width on those rims is towards the outside of the rim (as compared to your factory rims). So, imagine your current tires sticking out an additional 1.5". It may be possibly more because of the offset. I haven't done the detailed analysis of exactly how far the tire would move out.
