The stock lug nuts felt about 25% over the recommended torque -- the impact wrench that a neighbor lent couldn't budge them. Then later on in the process after the new wheels were placed, I finger tightened the lug nuts, lowered the car slightly, then torqued all lug nuts to 76ft/lbs, slowly tightening using a star pattern over several passes.
Later that night, I made a half-assed attempt to peel out near Alderwood, and the tires just said NOPE.. *grip*. I'm always amazed with the difference in handling that a set of aftermarket wheels and tires provide.
