The lug nuts on my Focus are turned to 90 LB-FT by specification. I easily do it with one arm. I always use a torque wrench so as not to over-tighten. Hitting a spinner with a 5 LB hammer easily exceeds 90 LP-FT. Most Cobra owners over tighten the spinners which then get even tighter with age leading to broken spinners during removal. To install a wheel, get the spinner very snug and then a couple of firm hits. That's it.
Just for the record, torque is measured in "LP-FT" while work is measuerd in "FT-LBS".
