If you don't mind my asking, how tall is the ceiling inside from the floor? By the pics, it appears similar to mine, but like you, I didn't have the height for a two post. My ceiling is 9' from the floor. The style that you have might be an option for me tho. I'm impressed at the height you can get from it.
I went with a 9' ceiling on mine as well. With my car, I can max out the lift and still have a little space between the roof and the ceiling. The total height of the lift at max height, not including the lift itself, is 48" - if it was not recessed into the floor and you drove over it, total lift is in the 50"+ range
Nice Shop, btw!
