Here's a pic of my new setup. I am only parking the Cobra in this garage for now, so I have not gone to the trouble to relocate the garage door opener to the side to get more overhead clearance. The ceiling is 10'3", the door casing is 7' tall by 9' wide. I had them replace the 7' door with a 9' door to get the tracks up as high as possible.
In this pic you can see I can't raise the car high enough to drive another one underneath. I am just using this thing for maintaining the Cobra right now. I can get it a foot or so higher if I shut the garage door.
If I want to park another car, I need to move the garage door opener, or just remove it and lift the door by hand. I can also back the Cobra in so that it's rollbar and windshield are to the rear of the raised door and get to the max extent of the lift.
