Do not put Loctite on the area of threads where the Pin Drive nuts mate.
Standard torque for the BMW 12mmX1.5 lugnuts is 70-80ft lbs. For me 70-80 felt a bit high as internal wrenching lug nuts (tuner lugnuts as some call them) are notorious for stripping in the Allen key area (I have experience on that). I went snug star pattern and approx 30 ftlbs and then 60 ftlbs. There is not concentric locator hub and my concern was more a off-center walk that could cause a vibration.
