I am thinking about picking up a cordless impact wrench for tightening of wheel stud nuts at the track. I don't know much about impact wrenches, however, and I am wondering how the level or torque is controlled on them. For example, if I want the nuts to be torqued to 75 ft. lbs, can this be set on the impact wrench exactly? Does this function vary by wrench? Anybody used one that they can recommend? I see guys at the track using them often but I never it is the winter and there are no track days so any help would be appreciated.

I don't mind using the trusty manual torque wrench, but those impact ones look pretty sweet.
