Wheel chocks...

[DYL]

I searched, and didn't find any threads on this already. I'm looking for some wheel chocks, to stay safe when I am working on a jacked up car. Ideally they wouldn't take up much space (stackable or collapsible). There's some foldable wheel chocks at harbor freight, but they need constant force on them, otherwise they're so easy to collapse that they scare me. I don't trust them. Right now, I'm thinking some stackable, one piece steel wheel chocks will fit the bill. I'd probably get 4 so that I can properly secure 2 tires. These are the ones I am thinking of getting: http://www.walmart.com/ip/Steel-Whee...nd-RV/29407175 .

Not sure if they're high enough, though. What do you use, and how many?

I get a blank page when clicking on your link.

Older ('80's) BMWs came with yellow metal wheel chocks - they were excellent, had teeth that bit into pavement. You could likely get one by looking in an old Bimmer's trunk in a junk yard.

Or, I've been known to use any handy rock.

One will do, diagonally opposite the wheel you're jacking.

That would be pretty freaking awesome to have a set of wheel chocks harvested from '80s BMWs. I might go look in a junkyard first

+1 up thru the E-46's had them. Once BMW went to the "run stupid" tires, they took them and the jacks out of the car.

Execptions: The E-46 M3 doesn't have either so don't bother looking in them.
