i have 16x8 +10 offset rota grid offroads with 225/45/16 dunlop z2's and they fit well with my b14. if your doing autox or any sport driving its a really great set up. i did roll the fenders slightly, but if your going for the "tucking" look, i would go with a 25-35 offset depending on if you go 215s or 225s, also depends on tire manufacturer. like my dunlops fit better than my toyo r1r's but same size.
