[QUOTE="ANGREY, post: 16040613, member: 188865"] This is one area where Ford Engineers dropped the ball. The reasons for not overtorquing are numerous, but the biggest being warped rotors and sheering off lugs. Ford eliminated the first concern with the 2 piece rotors, but if the loads were such that they're concerned about material deflection and vibrations, they should have gone with a 6 lug configuration or even more. Even hitting a tractor trailer with an air gun hard probably doesn't equate to 150 ft-lbs torque wrech and instead of asking for some ridiculous torque load on 5 lugs, they increase the amount of lugs accordingly. I get that weight is always a concern, but they didn't seem too concerned about wheel weight/rotational mass when putting 33 lb wheels on the regular 350 (outward where it hurts way more than at the central hub). They should have just gone with more lugs. This isn't NASCAR or Le Mans where you're worried about Pit times either. [/QUOTE]
