Where do you place the jack stands?
Under one of the lower front suspension attachment points?
I jacked up the back from the diff and then slid the jacks under the car where the jack points are..so instead of putting the jacks there...I put the jack stands and to not damage the car, I put hockey pucks between the car and the jack stand...hockey pucks are hard enough not to collapse but soft enough not to damage your car....then I proceeded to slowly lower the jack until the jack stands took the weight of the car....then I pumped the jack back up on the diff but just enough to touch the diff just in case the jack stands failed.....then did the same thing to the front and thennnn I took the wheels off.....the car stayed like that for 3 days....with no problems
People might advice you otherwise to what I am saying, and if they are more experienced than I, then you should listen to them. Since you had no replies, I figured I would give you my experience.......take it or leave it at your own risk

Kidding aside, I do the same like bmstyle, put the jack stands then jack it up a bit with the jack for double security
Personally I would never jack up my CL65 by the differential. It may work but why risk it when it is not necessary? I simply put my floor jack with a pad designed to work with the factory jack points under the front jack point on one side and easily lifted the entire side of the car. I put one jack stand under the front lower control arm right below the strut attachment and another jack stand under the rear jack pad/point and lowered it onto them. Then took my floor jack to the other side and did the same thing there. Car is sitting now on 4 stands with all 4 tires & wheels off the ground.
Sitting this way it is very stable and safe with no risk to anything and no lifting from a questionable point. Might be tough if you don't have a good floor jack that can lift 1/2 the car, but if you don't then you shouldn't be getting under the car anyway. I would never condone getting under a car supported only by a hydraulic jack.

Also, I wouldn't put stands half-way along the suspension arm - the car is still still sitting on its suspension (kind-of) AND sitting on the stands. One or the other is OK, but not both.
For reasons of necessity, I think I've had my car on stands more than I driven it, and I always put the stands under a meaty part of the subframe. When you put the second stand in, go back to the first one and lift it briefly again. This helps to make sure it wasn't put under any side-load when the second went it. You want the weight vector on each stand to point vertically downwards, through the middle of the base of the stand, not near the edge or corner of the base.
Putting a car on four stands is potentially dangerous.

+1 Never trust a jack by itself. I'm still trying to figure out the best place to put my jackstands on my w208 CLK 320.
Having said that: I love to see a CL do 10 second 1/4 mi runs. Awesome video! Thanks for sharing.
