Wow, that's a lot of calculating! Your prospective fronts are about stock. I would add a 10 or 15 mm spacer to push them out a bit. Don't go overboard as this could cause handling problems. You need 18 mm to bring your rears out to stock. Again add on 10 to 15 mm to push them out a bit, so roughly 30mm should do the trick for the rears.
