Break the lug-nuts loose by hand and use a 21mm socket on a 3" extension in your hand. I can get wheels off almost as fast as using a powertool. You're not a NASCAR pitcrew that has to get it done in 17 seconds.
I've almost gotten in a fistfight with the dumbass @ NTB that was insisting that he was going to use an impact to loosen/tighten the lugs on my green Z after I explicitly told him not to. I told his manager who came out to put my car back on the ground, I'm out. Idiots.
