I have a roll up door in my garage with a 2 post asymetrical arm lift. I have never been sorry for my decision for the 2 post but do see where a 4 post might be ok. I just didnt want to get my car on the lift only to have to jack it up to get at the wheels or suspension. I have a 12' ceiling with a 8' tall door. I had to install a longer track and 2 additional panels so the door went high enough to clear a car when it was on the lift. The local overhead door companies should be able to supply anything you need. A longer door opener track was also required but the local Lowe's had the parts.
