I think there is a reason that GM specified 14mm studs for Camaros, and Ford does the same for Mustangs. These are heavy cars capably of generating serious acceleration forces in all directions, and the 14mm studs allow a higher clamping force which is important to get the proper friction between the wheel and hub face.

Here is a diagram I got from tire rack. Although based on this 140 lbs is over tqed for our 14x1.5???
That diagram is all kinds of jacked up. 14mm and 9/16" are practically the same size but they are calling for wildly different torque values there (and no pitch spec on the 9/16" values). Again, all the vehicles that I've seen with 14mm studs specify 130-150lb/ft of torque.
