Op, you really need to pay attention to the offsets. For instance, an 18x8 with a +35 offset will be completely flush with the fenders, while an 18x8 with a +48 offset will be sunken in much like the OEM wheels are. The same model of wheel, with just that one change.

I kept the OEM wheels and used spacers to push them out. The OEM wheel is 17x7 +48. I have 20mm spacers on the front and 25mm on the rear. This effectively makes the offset +28 on the front and +23 on the rear. My wheels aren't flush with the fenders, but they're close. I probably could have gone with 25mm in the front and 30mm in the rear.

If I was buying wheels, I would get 18x8 +35 with 225/40-18 tires. This would be flush in the front. Then I would use 5mm or 10mm spacers on the back to push them out to flush. Keep in mind that doing this will require longer wheel studs at the rear. You really shouldn't go longer than 3mm on the OEM studs, or you risk not having enough threads to get a solid engagement with the lug nuts. Once you get to 15mm or so, you can use bolt-on spacers, which let you use the OEM studs.
