ditto...
18's would definately rub and you'd be buying a new set of tires every few days, not to mention the align being so far out of whack that your going to need a set of adjustables just to make it all work, the tokico's are nice, i've been running on those for a while now w/ eibach pro kit, had to get the adjustable ball joint to make it fit perfectly, but i dont burn thru tires and my align isn't that much off.....good luck though
