[QUOTE="ANGREY, post: 16039862, member: 188865"] I'd be much more concerned about the torsional capacity of the studs. The longitudinal tension capacity of a steel bar the diameter of the studs is quite large (i.e. how much load is pulling on the threads to pull the stud outward) but when tightening, 150 ft-lbs is terrifying because doing it "dry" runs the risk that the threads bite a little too much before it's seated (and friction of the seat to add to the torque resistance) and "snap" there goes a lug. I personally am not tightening to more than 130 unless I go to the track with it. On the street, there's absolutely no reason to torque them that much and for as many times as I yank the wheels on or off, it's not worth the risk of snapping a stud. If I go to the track to beat on it and the wheels feature their max loads, I'll torque them down to spec. [/QUOTE]
