Never torqued a wheel nut before, so I can’t speak on that subject. I have used both the Ridgid and Milwaukee 18v 1/4 drive cordless impacts for wheels on a regular basis and never had one come loose, although lately I’ve been just doing them by hand.
As a side note, I use a cordless impact for kart stand assembly every single day, and the Milwaukee 18V with the Lithium battery is the best one I’ve ever seen and its quite inexpensive.
