4 post in my 2 car garage. A 2 post wouldn’t have worked well in my space. 95% of the time I just have 2 cars stacked for storage, which leaves enough room along the side of my garage for my workbench, tool chest, and a parking spot for my motorcycle. I use a bottle jack for wheel work. I also bought an under hoist jack stand link below. I can set this up under the car while its up on the lift, lower the lift to raise one end of the car, then place jack stands between the car and the ramps. I’ve found that with my race car which is very low, I can’t fit a bottle jack under it that has enough extension to get the wheels in the air. The under hoist jack stand has been a great companion tool.
