 The 285 is 1.2 inches wider, plus the offset is around .8 inches closer to the fender.  So, at a minimum, that tire will need like 1.5" more fender clearance than your '05 Sti.

 Ah this is not totally true.  You cant say it is 1.2" wider it all depends on the brand tire.  Gus has 285 yes however he came over with a wheel and his tire is significantly narrower then my 275 toyo r888.  they are more like my 265 advans.  Either way he will have a hard time fitting them because the wheel off set not so much the tire size.  I can run a 305 with my widebody with the right offset wheel however i am having troubles running 275 without rubbing because i have a 10.5 +22 wheel.  By the looks of the picture you posted i would get a less tall tire, a "265", loads of camber, and a fender roller.  Or you can do what reid did to his evo and flair the rear fenders.  I think pancho charged him like 500$ and you can fit those 285 no problem with stock camber in the rear and a little more -camber in the front.
