I got 14" steelies with Blizzaks last year for my 98 SE. I didn't think they would fit at all without grinding the heck outta the calipers on my NX, but they fit without a hitch!!!

So if anyone worries about 14 inch rims for Nissans with 4x100 lug pattern from Tire Rack fitting over NX brakes, you are in the clear. :)
