The only time I use an impact wrench is during pit stops in a competitive environment. I don't use an impact wrench any other time because it can knock the crap out of your wheels, your lug nuts, and it strips the threads on your wheel studs. Use a breaker bar to break them loose while the car is on the ground, then lift car and use a battery powered driver to spin them off carefully. I have no problem breaking loose by hand from 150 ft. lbs. on my GT350.
