I seem to remember back when I had my 997 that there was a specific order to lifting your wheels to enable the car to be put on 4 jack stands using one floor jack.
In another thread i earned wheels guides are available, making the removal of wheels a lot easier, so I'm going to get the wheels of once the guides arrive and give the calipers etc a good clean.

But how can i get the entire car on 4 jack stands using one floor jack?

Thanks a lot

 

Here's a link to a quick time lapse video of a 996 going up on jack stands. Search youtube for plenty more. Safety first!!!!
I'm sure if you call your Porsche service department and let them know you want to clean your wheels/brakes they will have some advice for you.
