There was a very long jackstand thread a while back. Got pretty far afield though...

The short answer is that jackstands with a flat top work better under the jacking pads, if you can find them.

Of course, stands with a concave top work better for front suspension work where you need to support the control arm...

I'm still using the concave ones with a sacrificial block of wood until I get around to fabricating something better.

I got a rubber saddle for my floor jack, which is great. More useful for general purpose use than the metal cup saddles. Hardly ever take it off...
