car lifts
5”-5-1/2” thick 4,000 psi concrete with rebar for the base. Each post has six 3/4” concrete anchors set 5” deep and torqued to 140 ft lbs. Hole locations are not a worry, you set the posts in place and simply drill through the base plate holes on the posts. Don’t waste your time with your 1/2” Chuck hammer drill, go rent a true impact hammer drill. It took me 1 days to drill 6 holes with my 1/2” drill and about 10 minutes to drill the other 6 with the rental.
The lift itself doesn’t have to be expensive. I got mine used from a dealership that was upgrading to 10,000 lb lifts. I had to replace the cables because I was changing the width & height of the lift, but I was still into it for less than a grand. And it is built like a battleship.
And wow, what a game changer for a guy like me. Before, I would get so tired from all the up & down, you know, roll out from under the car, get to your feet, go to the toolbox, get back down on the creeper, roll back under, then repeat because you have the wrong size. It just wore me out and made it not fun to work on my cars.
Now, if you have to go to the tool box, no prob, just duck your head a bit and walk over to the tool box.
Get the full size lift!





I found that the concrete varied from 3 1/2” thick to a little less than 3” thick.
Before I would install any 2 or 4 post lift I would cut out 14” square sections of the garage floor, dig at least 12” deep footings, add rebar and place good anchors as you pour about a six bag mix of high strength concrete.
But I’m known to over engineer and over build everything because we live in earthquake country.

I looked into a quick jack and set up takes just as long as a jack with jack stands from storage. If you leave them set up on the floor, it goes faster. Also not sure if it would even work with my C3 with side pipes. They hang pretty low. Also when I jack up my C3, I support the front closer to the engine mounts to reduce flexing of the body. Maybe that is not a huge concern since most of you are lifting from the standard point behind the front wheels. I guess for now I will stick with the hassle of jack and jack stands. But one of these days, a 2 or 4 post lift would be awesome.
Now this old fart uses Race Ramps. They have some pretty innovative designs. Recently did a trans swap with them, plenty of height.
Low approach and they seperate after car is raised to allow plenty of room to work.

Also, there are many thousands of 2-post lifts correctly installed around the world that don’t tip over. It’s the poor installs you need to worry about.

You could damage the front crossmember if you don’t protect it.
I jack the front first by placing my two jacks at the front frame jacking points, one on each side and jacking a little side to side, then place jack stands right next to the jacks.
I do the rear both sides together at the rear jacking points on the frame then place the jack stands.
Chock all four wheels before you start and place the transmission in first or park.
What I do is put the front on RaceRamps. Then lift by the diff (or a straddle-bar on the rear spring, across the exhaust), and get the rear on jackstands. Then, if I need all 4 wheels in the air, I lift by the front crossmember, only a little bit, to get the front on jackstands. Removal is the reverse.
This way, the car is never tilted, lifted by a corner, or pivoted more than a few degrees on jackstands. Below is step 1. The 2x8s under the rear wheels give me the clearance I need for the spreader bar and cheap floor jack.
