GO FOR THE +55 ON 18x7.5.
I'm with Dave. Get the 18X8 or 18X7.5 with the +55. While rubbing may not by an issue with the lower offsets, you will defiantely stick out in front if you have 0 degree camber with anything lower than a +48. I base this on my 17 X 7 with +46 rims, With 0 degree front camber, my front rims stick out about 2 mm or so. It is not much, and a very slight .5 degree negetive camber tucks it in nicely, but stil, it will stick out if the conditions are right. And I only have a 7" wide rim with a +46mm offset.
Now keep in mind, my firend actually has a 17 X 7 with a +38 offest. With 0 degree camberm, the front rims used to stick out about 4 mm or so. Also note, his 7" rim has a total width of 200mm, while my 7" rims has a total width of 202mm. With 215/45 ties on his car, lowered about 1.75" with Eibachs and konis on low, and corected camber to about .5-.7 negetive, his front tires are perfectly flush with the outer lip of the fender, and he does not rub at all. So, how you set up your front suspention like camber and ride hieght will determine how low an offset you can get away with. Also the total width of the rim will also play a factor. The 7" designation are all standard for the measurement of where the tire bed is, but the over all width depends on the rim design. Just as my friends 7" rim has a total of 200mm, and offset of +38, and mine has a 202 total and +46, the offsets are only reletive to our own rims. As If he had a 200mm rim with an offset of +46, he would essentially have a more positive offset than I do with my 202mm +46. For example, a +50 on a 200mm rim would have 100mm on each side. A +50 on a 202mm rim would have 101mm on each side. You have an extra 1mm sticking out on each side of the rim, and that 1mm could determine of you just clear, or barely rub.
