Ansch,
Use 40 profile at the rear because the rear will be lower than the front. Not exactly lower but if you see your first pic, the front fender is higher than the rear fender if you see it horizontally thus making the front "look" higher if you lower it. So you'll need 45 profile to fill up. Keep running 255/40 at the rear. More grip
