I have 12' ceilings. I had to cut my lift down 8" to fit it in. It will still lift to max lift, but not if I have a tall car on there. I can't stand up under the bus, but I can stand up under the 911 and most other cars. I'm 6'3". I need to move my garage door opener to the wall when I put a new door on and move some lights around for more clearance. Pardon the mess... I had just put it in and moved some things around.
