Let's see a pic of your car on the 18x18 version.

Built these this weekend 17"x12" screwed together cost me about $45 and took about a 1/2 hr for each one. Which seemed like a long time but it was a lot of screws

Always wondered how you guys get under a car with any confidence when the ground could shake at any time!

I went 16x12 i believe. I went just high enough where my big floor jack could get to the bottom of the housing. Stable as can be. No clue why the pics are upside down.....Buy a Mac they said.....

I made mine 16" long x 14" wide. I also made them so each corner is actually 2 cribs stacked since my jack wouldn't lift my car high enough in one shot.

As far as strength goes, we used to stack 20k lb roof sections on 36" high cribs (one at each corner) built the same way.

Glad you asked the question as I need to build a set myself. I have a two post lift, but there's some things that require having the weight on the suspension.

Lance I was under the Firebird many moons ago
with it sitting on jackstands when we had a 5.0 quake
I was out from under that car in no time

It does make you think about it
My new shop has t-bar ceilings with 2x4 drop-in
lights.. I don't think the lights have the extra wires
and there are no compression posts on the ceiling grid
that we normally do on new ceilings...(I am a contractor)
The building is metal and will flex but I am sure lights and ceiling may not
be good bouncing off the cars

I made mine 16"x16", 6" tall. I also made them where I could interlock them together and get additional heights at 6" each. Best money I've ever spent. Although, (and it takes a little work) find where someone is building a house and ask if you can go through their scrap 2x4's. I'm betting you could probably get enough free wood to build them.
