Car this is going under was hack minitubbed, going back stock width. Using fifth ave 15x7 steelies all around. Honestly i dont know how much your really gonna get out of a 1/2" offset kit especially with the rim size i got going under there.
15x7 will work great but not much room for if you ever go wider. with just a 1/2 offset You have the possibility of 15x8 or even 15x10” if you pay attention to what tire your running and back spacing. Just a suggestion.
