It works fine until it doesn't. A tire shop in Houston bought my dad new studs when it didn't.

 

Get the torque :limiting: bars for the impact wrench. They have them at harborfreight for pretty cheap.

 

i even had some 'more expensive' lugs that were like 50$ muteki or some crap on my srt-4 and i torqued them quite a bit and the finish never came off after a bunch of removal/installs..



moral of the story, don't buy expensive lugs, no point.. and if you did have expensive lugs that chipped/flaked, you made some company VERY happy by putting lots of money in their pockets.
