Think about a 3/4 drive breakerbar and socket for lugnuts, it really,really stings when you over torque that 1/2" breakerbar and it dies in your hands/feet, being superman"stronger than sreel is not all that it is cracked up to be in my humble opinion.
Look around, truck parts and farm supply stores, I have seen large 4way wrenches with a hole in the X that will accept the round end of a 6' Johnson bar, start with the 4way paralell to the ground put the bar in the hole, step on the 4way and pull on the bar and use it to help turn and control the 4way.
