If you do your own wheels, 19#-20# foot pounds per bolt is the correct torque. BBS will not give this info out, maybe due to liability, but I verified it with a shop in town and when I tore my wheels down, I used a beam torque wrench, and those were the same numbers.
Keeping this in my back pocket for torque settings...
