Impact guns are not the problem, its the users that are. I can break loose and tighten bolts tighter than any 1/2" impact will do, by hand. Most Japanese makes require less torque to secure the wheels than American brands. Isuzu used to be really problematic. The Rodeos and Troopers required less than 65ft-lbs to tighten the wheels. 80ft-lbs would stretch the studs, and 100 would lead to breakage the next time they came off. That's not much. I can torque most wheels in the air with just one hand holding the wheel. A four-way tire iron would easily surpass that. Poor workmanship is the issue, not the tool.
