I have a friend that also coffered his ceiling so he could use his 2 post rack. Only problem was that one time he didn't have the Cobra parked on the correct spot so when he raised the car, he produced a little more "coffering". I didn't tease him.... too much.....Tom's "tray" was much safer.
When I was young and agile, I worked under a lift. When I retired and was old and creaky, I was rolling around on the floor. Not good. Hence, garage addition, with 13' ceiling and a four post lift. Life is good.
