Mine is for a 4-door. I'm not sure how high the ceiling is in my garage, but I'd say you need at least 96". Mine is tight with a 2.5" lift and 33's. Again, if you're interested, I can measure everything for you.
Kren - if you're interested, I have a new one of these lifts in the box. I ordered one from these guys back in August. I got an email saying that it had been backordered and then another one saying they were having to find another manufacturer. I decided to buy the same lift from a guy on ebay and thought I had canceled the first. It showed up on my doorstep about 3 weeks ago. I didn't want to pay to ship it back and figured I could find someone who wants it. If you're interested, I can send you photos of mine installed and the one still in the box.
