Dwight,
It's made for 8' ceilings, but higher is better! The post are right about 6' tall, of course you add the height of the car to it and you might end up with a new "sunlight" in your garage!
Since you've seen the shop you know how packed it is. The roller package is a true blessing! We assembeled it in less than 2 hours, (book said 4) and then proceeded to roll it all over the shop just to see how it would work. With only inches to spare between parked cars, two of us "drove it" from end to end without a problem! One guy can move it easily, but two guys definately have more control.
Should have done this years ago!
DV...I'm going to see if I can't get "American Lift" to help sponsor the Fling! Maybe we can ge one to raffle off with the KMP Cobra
