I have a set of wheels that I use for track and a set I use for street. I figured I'd buy a cordless torque wrench to try to speed up the process of switching them... So I won a used one on ebay, and tried it out... it did nothing on the lugs, in fact I could hold the socket in my hand and give it full power and it just sat there and made a bunch of noise... So I returned it, I bought a brand new, more powerful one and once again, did nothing.... I'm no mechanic, so am I to assume that the cordless torque wrenches just don't have enough power to remove a lug nut?
