I am getting close to purchasing a set of track wheels and will be doing monthly tire/wheel changes for autocross events. I have a 1/2" torque wrench, but I would like to use an impact wrench to remove and partially re-tighten the lug bolts. Which would be better for my use, an electric wrench or an air wrench? I currently own a compressor that is capable of operating an air wrench. I realize that the air wrench is much more powerful, but in this case, that might be a detriment. I certainly do not want to accidentally over-tighten the lug bolts.
