I've been meaning to post this thread for a while. I'm sure there are easier and better ways to do this, but I've got a way of getting the E92 on jack stands at all four corners providing you have or can borrow three floor jacks.
Disclaimer: I'm not a pro. If you do things wrong, you could wreck your car or kill yourself (or both). You have to be confident in your own skills and you have to know that your equipment is designed for the job at hand with sufficient capacity to handle the loads. I also might be doing something wrong here. I don't really know. So use this information at your own risk.
First, chock the back wheels, take two jacks, put them under the two forward jack points (the plastic blocks just behind the front wheels) and jack up the front of the car evenly.
Being somewhat paranoid and playing by the book, I located jack stands just in front of the jack points at a spot on the frame that would work if a lift failed. (It might wreck the plastic trim, but it wouldn't wreck me.)
Then get under the front of your car and locate the forward central jack point which is a nicer rubber block projecting through a small rectangle in the plastic underbody shield.
Jack at this point to lift the car off the floor jacks at the sides and move the jack stands to the forward jack points. Pull the side floor jacks well clear and carefully release the front central floor jack to set the car down on the forward jack stands.
Now lower the side floor jacks, put them under the rear side lift blocks, lift evenly, and provide yourself with backup jack stands. Get under the rear of the car and locate the transverse frame beam which is between the gas tank and the differential.
Do not jack on the differential. Using a wooden block, take the third floor jack and jack the rear of the car at this point lifting it off the side floor jacks.
Now pull the side floor jacks clear, position the jack stands, and set the car down on the rear jack stands.
I've done this a few times, and with practice, it doesn't take long at all. Remember that floor jacks have to be able to roll smoothly forward and back as they jack. If you forget this and a jack gets caught, it could pull your car one way or the other which might cause some horrible accident.
