Garage floor
Dumb question for the day. Moving to Indiana. The garage has high ceilings perfect for a lift. How can I figure out the thickness of the floor without drilling a pilot hole?

You could get a four post lift and not worry about how thick it is. I love mine.
If you decide to go with a two post and the concrete isn't thick enough you can hammer up two spots and do two 2 foot deep (or deeper) 12" round pylons. A little labor intensive but not an expensive way to do it.

I don't think so. It depends on if you get the optional hydraulic lift arms. Even if you don't and you use aluminum speed jacks just to get the wheel off the lift runner it's way better than laying on the ground. And a lowered C4 rolls up on one no problem.
Different lift designs have their pros and cons. If I was working in a shop where time was money then a heavy duty two post would be the best choice. But for a car guy doing it as a hobby I feel that a four post is better. One big reason is the ability to park a car under the one on the lift for storage. They are also much safer and more stable than a two post. I can really wrench on something with a cheater pipe with the car 7 feet in the air and not have a care in the world.

That and Aplus brand lifts uses the 12"x 24" pylon as a recommendation for their lift. But that is a minimum size for their smaller two post.

Nope. I have a Rotory 4 post lift. I have a piece of channel I put between the ramps on the side rails. I can use a bottle jack anywhere along the car on either side. I've replaced brake lines, pads, rotors, shocks etc with ease. Welcome to Indiana!

Another big perk to a four post lift is the fact they can be moved. So if you decide down the road you want the lift moved to the other side of the shop you can do it. Mine even came with wheels that pin to the bottom so you can slide it around. Not with a car on it of course.
