There would be a difference between a car falling off a lift (or the =

post lift. I don=E2=80=99t think the issue is the two post lift =

transmissions on a daily basis sure they make sense. Maybe it is just my =

twice the rated capacity. I think as long as the Tiger isn't shaken off =
the lift then it's a pretty good bet that the lift won't collapse.=20
