Jack up 912
 
Hi,
New, proud owner of a 912. There's quite a lot of work to do and with the limited space i was leaning towards using these to make it easy to put close to the wall when not working on it.

Now, I have done quite a lot of searching for jacking points etc, but, all i find is how to jack it up, one side at a time.

Do anyone know if I can use the below for my 912 and if so, how :-)

It looks fine if you want to elevate the car for some long term work, but it is such a cumbersome device that once you managed to install it under your vehicle you would never want to remove it for a simple enjoyable outing. If your only need is for the ability to move the vehicle sideways for storage, consider wheel dollies.

Yeah, they will solely be used when i am doing work on the suspension and undercarriage. Once drivable, dollies for sure!

Any idea how to lift it securely onto the described stands?

I use one of these.

And when the suspension is off, one of these from Stoddard.

I would be reluctant to put my car on that dolly without the front and rear being solidly connected. Plus the wheels are so small the smallest little pebble will cause the car to resist movement. Ask me how I know. And with the front and rear not connected that could spell disaster.

The assembly your showing is for either the back or front, and the force of the weight does not seem to be centered on the wheels, but is rather offset few inches. So as @cmpski suggested, there will be a lot of rotational force (toque) on those four bolts in the center.

Besides, I never use a single system when stationarily jacking up to e.g. pull the engine, and use triple redundant sets of jacks, in case one or more fail. So using one system may not be safe in your garage, especially after looking at the engineering and rotational forces of the system you showed. You could use those rollers which go under each wheel, but that's not jacking up - but rather moving around freely for storage.
