Corsa Install?

Tomorrow will be the day to install it along with a skip shift eliminator, factory mud guards, and Oil change.
I am planing on lifting the car simutainesly at each end with two floor jacks and then setting it down on four jacks stands at the four outer lift point under Aluminum pucks.
Has anyone ever set their 09 down like this?
It just seems that Steel Jack stands under Aluminum Jacking pucks would be slippery.
The pucks do sit flat in the Jacks Cradle though overlap by about 1/4.
I hate to sound like a Sally, extra precautions sure can't hurt..
