There must be some conversion error here.
I tighten my lugs to about 100Nm, which is what the dealer told
A pound is about 0.45 kg, which amounts to about 4.5 N force.
One foot is approx 0.3 m.
1ft-lb => 4.5 * 0.3 == 1.35 Nm.
80/1.35 equals about 58 ft-lb.
Now 80 Nm sounds a bit low to me, but 80 ft-lb -> approx 110 Nm sounds
