Not being a civil engineer, I recommend you check with the manufacturer to see what they recommend for footings. Local building codes may also come into play. (I don't like gov. getting into my life either, but the codes can save a life.) Many times the soil under the concrete settles leaving a hollow area that can often be heard if you hit the concrete with a 2x4. Again, as I mentioned earlier with regard to welds, you certainly don't want a weld or the floor failing when you or an expensive car is under the lift!!
Bend Pak states that for a 9,000 lb four post lift to have a minimum thickness of 3-1/2", 2500 psi concrete. Note the word minimum. The XL-9 (9,000 lb twin post) and PR-12F (12,000 lb twin post) require 4 inches and 6 inches, respectively, of 3000 psi concrete, as a minimum.
Just my opinion. Think of this as never, ever, getting under a car with only a jack. The welds and concrete are the "jack stands".

The other is I think I only have a 3" concrete floor in my shop. Is there a downside to using an asymmetric lift for storage/parking? I wouldn't think it would be good to let the suspension hang on all the bushings. Also, for unibody cars, if you don't hit the jacking points exactly, would it bend the body over time?
