lifts
I read the discussion on 2 vs 4 post lifts, but still have a couple of questions. Can you park a car under the 2 post lift if its up in the air.,with a car on it. It looks like the distance between posts is about 8'6" so it looks to be enough room to park a car under .
. Can you leave a car in the air for an extended period. I was on ebay , and they show a car parked underneath the 2 post. If I have
a 4" slab , what would I have to do . Have a mason cut out where the columns are, and put in thicker concrete. I ordered a 4 post at Carlisle, but have to get the door tracks raised, so lift is on hold. so I may change my mind and get the 2 post. Thanks in advance, JIm.

Yes, you can park a car under the lifted car on a 2 post lift.
Two post lifts usually have safety stops you can use to take the strain off the hydraulics if you're going to leave it under load for extended periods.
Some people are hesitant to leave a car supported by only it's frame for extended periods because it may cause problems with the fully extended suspension or because it may put unwanted torque on the frame. I don't know if these concerns are valid for the C5 or not.
If you have a 4" slab of 3,000# concrete you're probably good to go with a concrete drill and some drive in anchors. Good Luck with your installation, and get somebody to help you, those things are heavy.

A friend and I have a 2-post Rotary asymmetrical lift.
As for leaving a car suspended on top of a 2-post lift for any length of time, Last C5's answer above is as good as mine, so I'll leave it at that.
Installation requirements will vary depending on the type and size of lift. If you go to the Rotary web site, http://www.rotarylift.com/, then click on Service and Support, then on Frequently Asked Questions, you will find a lot of information on installation requirements for each of the different type/sizes of Rotary lifts to include concrete, electrical, and height requirements, recommended bay sizes, etc. etc. Rotary was the only brand we considered, so I don't know if some of the other brands of lifts have this type information at their web site or not.
Should you decide to go with a 2-post, be sure check out the 2-post asymmetrical lifts as well as the symmetrical. With the asymmetrical lifts, the center of gravity is further back from the lift posts allowing the doors of most vehicles to open wider. We're extremely pleased with ours.
Hope this helps and good luck choosing the right lift.
