Also, use anti-sieze on your lug nuts and you wont have to deal with them rusting on.
You can buy a torque extension for your impact. They make them in 65,80,100,110,120 and 145 Lb ft of torque.You simply put them on the end of your impact and attach your socket to them. They limit the amount of torque your impact can apply to the socket. Much faster than a torque wrench.
