Default 12" x 18" rear wheels, what backspace?

hi, i just ordered some intro wheels in 12" x 18" rear and they ask what backspace i want... im nut sure if 4" is ok or should i have 5"? the car has wide fenders and now its got 15" with 285 tires and 1/2" spacer and the wheel looks really bad its like 2 - 3 inches inside from the fender lip... that why i want wider wheels... what would you recomend?

thanks and happy new year
