I've got a jack stand that allows you to jack up the car with a standard floor jack using the factory jacking location, place the jack stand in the same location, and then remove the jack. The car ends up resting on the factory jack pad on a fixed jack stand. Works very nice!

fnckr - You can't see it in the picture but the center of the puck is NOT supported - what is under the puck is the typical "V" shape. The pucks are held in place by the weight of the car - I suppose you could call it Gravity Attached. I might attach them using a countersunk nut/bolt and threading them into the jack stands.
Regarding the safety of the ratchet mechanism - I'm with Pcarhombre, I specifically purchased the "High Lift" version of these jack stands so that I don't have to use the ratchet mechanism at all. The car sits at between 14 and 15 inches. High enough for most applications.
I take safety very seriously - am I missing something here? My biggest concern is that this is earthquake country and the car could slip during a seismic event so I put the removed tire under the car as well as leaving the jack in an upright, closed position (but not under any load).
If anyone has any other safety suggestions I honestly welcome them... I just thought spending $400 on jack stands was a bit much - perhaps I'll get them in the future, they are very nice.

Just my 2c and gut/engineering feel....
I'd be a little careful with the hockey pucks since you are not supporting the centers. Here's why....I've see a hockey puck crack from being used under the engine case (on the center seam near the back), when it was used on a jack (to protect the engine and jack). This was a jack with a very flat pad, so good distribution of force. Yes, a lot of force on a small area, however that's what you might end up with since your puck is only supported by the two sides and not the center. My biggest worry would be the puck moving slightly, causing the car to slip.
As an owner of the Esco stands, I will say they really are awesome. I never liked the shifting the Pcar will do on the "regular" stands (which are really made for use on an axle or similar and not the flat jack pads we've got), especially raising and lowering.
my 2c, YMMV.

Easy to modify a set of these for jack/axle stands which are very cheap for a perfect fit:

They twist 90 degrees and lock in place into your p-cars factory jack points: http://cgi.ebay.co.uk/JACK-PAD-PORSC...item2305d8744e <-- No affiliation but about the same price as your $50 Hockey puks and made for the job

Thanks all for the feedback. I see the point of a possible crack - that does concern me. So, let's assume the puck fails (cracks and breaks). What would happen? My biggest concern would be a sideways slippage, followed by a downward slip, repositioning of the jack stands off the jack point and YIKES!
What do you all think about putting the solid aluminum style jack pads on the top of the "V" instead of the hockey pucks? I could even cut slots into those and bolt them onto the stands. There would still be the issue of the center not being supported but the whole thing would be stronger.
Also, with the ESCO and AC Hydl. stands what is to stop horizontal slippage? Like in an earthquake?

I've been using the pucks on the jack stands (ratchet type) and they work great. However, this whole dialogue was terrific!! I think I'm going to secure the puck with the countersunk screw/bolt idea--shoud make it more solid.
You guys are great--thanks.

Hockey pucks are amazing little things. The rubber is very dense, and machines beautifully. I have made all sorts of things out of hockey pucks: suspension bushings, vibration dampers for surface-mount assemblies, etc.

I posted this a few years ago on the 964 forum, works like a charm, and very inexpensive.
