Securing a Two Post Lift

[custom10nut]

I hope this is the correct place to ask.
Within the year, I’m building my new shop at my new Homeplace, and I plan to install a Two Post Lift.
As far as securing the Lift to the shop floor. What is the safest most secure way of mounting it?
J-bolts hooked around rebar in a beefed up footer?
Anchor bolts drilled into 4500 lbs psi concrete?
Is 4500 psi too much, and would the Anchors hold?
I plan to put in a 12k Lift, so that I can safely lift anything I have (P/U, Dually, wife’s car, and my tractor), but I know a Lift is only as safe as the way it’s mounted.
I’m not looking for “should be good enough” advice, but advice from those who currently have aTwo Post llft
Thanks in advance
