    The one i linked is a heavy duty, 300 ft-lb 1/2" impact driver that's on par with a lot of air powered impacts. This is built for real "impact" work, like automobiles.
    I am sure it would work fine to remove lug nuts since 90ft-lb is the spec! Not saying the 300ft-lb wouldn't be handy

    It's not... i have it.

    When you properly torque the lug nuts to 90 ft-lb you need over 100 ft-lb to remove them due to the difference in static vs kinetic friction.

    That impact driver is 110 ft-lb "max"... If you want to use it to remove lug nuts, you'll need to break the torque yourself first with a lug wrench. After that it does a great job of removing them.

    Yup I have to break mine loose first with that impact. I also measured the lugs after using the impact to put them back on at they were torqued to 50 ft-LB which I thought was pretty good.

    Yeah, there's a lot of torque loss in the socket connections too so 50 ft-lbs is pretty good.

    The impact already broke my 18mm socket. It wasn't an impact socket but I didn't think it would break with this
