I cannot speak to the alignment but it should work just fine with the right setup. I have a ACS made in the USA lift bolted to a concrete floor that sits on top of a gravel base. The lift has been in place for 4 years and has had no movement whatsoever. Grated the garage was designed for the lift and it is a beast of a lift. Most mechanical jobs are easier than doing it on the ground but harder than your standard lift. I use a scissor jack mounted on the lift rails to raise the front and a jack plate with a bottle jack and jack stands to raise the rear. Car is completely raised in under 10 mins. From that point most anything is accessible. Just watch your head, you will bump it hard at least a couple of times a year.

A couple times a year? I whacked myself a good one twice today. (yep, I'm smiling but not really joking. Off to the hot tub...)

My pleasure. Also don't forget, put the 2 shiny sides facing each other. They slide much better that way.

A car in the air on greasy plates with nothing to hold them makes me nervous. Gulp

Otto Mechanic

So, shiny side up/down, grease side down/up? I think I have it...

Otto Mechanic

Oh stop whining. Everything in life is a risk

kgorman

Haha!

On a more serious note, we had a 2.9 earthquake here today while my '89 944 S2 was up on the lift with both front wheels off; I'm setting the lower washers and nut on the engine mounts. The top bolts are in but not torqued and the bottom nut & washers are giving me serious grief due to the fact I can't get my bloody hand in to set the nut.

At about 8:30am today we had a 2.9 event. I was (thankfully) not under the car, instead I was enjoying hamburger and eggs with my lovely wife. It wasn't until about 7:00pm PDT that my mother called to let me know about the earthquake.

So for everyone's edification, a 4 post ProPark 9+ carrying a 1989 Porsche 944 S2 on jack stands lifted approximately four feet above grade survived a 2.9 earthquake without blinking.

Just one more anecdote for our collective notebook.

You'll notice the Bend-Pak lifts recess the plates so they can't slip off? You might be able to do the same sort of thing by setting stops (bolts?) around the greased plates (tiles) that allowed them to spin about 90* but kept them from sliding off the lift? Just thinking out loud because I'm seriously considering this too now you and Larry brought it up.

It's really all your fault you know. If you hadn't mentioned the possibility I'd be happily ignorant.
