So, made myself some wooden wheel cribs. Got about 7.5 inches height on it.
What is the best way to jack the C7 up and put cribs under? I do have 2 jacks.
I prefer not to jack car with a single jack from Front or Rear cradles. Seem like I'll break the aluminum points.
1. Jack 1 side up at a time and place cribs on front and back of same side of car . Then go over and jack the other side up and place cribs on front and rear.
2. Jack 1 wheel up at a time and place cribs
3. Or jack up Rear up using 2 jacks on each side and place a crib on rear wheel, then repeat for front tires with jacks on each side of car.
I guess we should never jack Front up FIRST? since E-brakes hold the rear tires in place. I the car might roll, when you jack the rear up after the front is already up in air.
My method may be frowned upon. When I change tires, I jack up from the front side. The chassis is stiff so the rear comes up too. I place jack stands and change the tires.
In my opinion, it would normally be ideal to jack up the front (or rear) of the car, and then drop it down on the front (or rear) wheel cribs. But, I'm concerned about the car rolling when doing that....especially the front wheels. So, I don't do it that way.
When I jack up the side of the car, both the front & the rear wheels come off of the ground.....although, one is maybe 3 inches higher than the other. I simply jack it up high enough to get the cribs under both wheels; then drop it down. I then do the other side.
As Maxposers stated above, the chassis is extremely stiff. It doesn't seem to flex at all when jacking up the car. So, I'm not worried about doing one side, then the other. With that being said, I have 16" wide Race Ramps wheel cribs; and tires stay firmly planted on the cribs while I'm jacking it up & down. They're also 2 peice cribs.....so, I can go half-way up at time, if I want to be extra cautious.

True that on rigid chassis. This is confirmed that when you jack it up the doors open and close easily. Different than the old days. If you are worried about the car rolling (which wont happen on a flat surface), put wheel chocks on the opposite side.

KISS.
chock the wheel of the opposite corner you're jacking. jack up car. set on stand or crib. done.
I jack up the front first, because as noted, the rears arent going anywhere with the e-brake on. Then I do the rear. My cribs have stops on the front and rear and I have never had an issue with the front wanting to roll. Coming down its the reverse, rear first, front last.

This is my main concern of jacking up the car front end up first then rear end up afterwards. So, ill try lifting from sides first then the other side.

Yes, this is how I originally would have lifted it up as well. But, after watching that video of the failed race ramp lift. I'm paranoid now of lifting front end up first then back end up.

Using the lift points, I simply jack the car up one wheel at a time, place a ramp under that wheel then move to the opposite side and do the same. Seldom have a need to do all four wheels, but when I do, the back is done just like the front.
