Does anybody know if the jacking points in the center, at the front and back, of the z06 are the same as on the standard c7? i'm going to get some cross beam adapters for my floor jack. Does anybody know the measurements? Thanks in advance.
I won't have the car until next month. The manual doesn't have any dimensions, that I saw, and I am having some cross beam adapters made for my jack. I just wanted to make sure they are the correct size for front and back jacking points.
For the sides you just get a set of 'stay in' jack pucks, they cost $45 ... to lift by the wheels my understanding is that you jack under the aluminum control arm. Again any flat surface jack will do, and you can put some cloth in between for extra protection. Just make sure you get a jack that clears low enough >5" and even lower if you plan to drop her a bit ... mine has 4" clearance.

i'm looking for a way to jack the whole front, or rear, of the car at one time. That way I can set it on wheel cribs to work on it.
The only thing I can find on the manual that refers to jacking points other than the frame ones on the sides are these, but you probably already know this.

Thanks. That was all I could find too. The shop manuals won't be available until may from Helm and my tpw is 3/16 so it may be the first of April before the car gets here. I was hoping I could get some measurements and have the crossbars made before I got the car. I may just wait and see if a 2x4 works as well it doesn't look like there's a lot of space there anyway

As long as GM recommends jacking in the middle of the cradles maybe just do that. I understand wanting to use an adapter, I always have done it that way. The cradles are now beautiful hollow castings that are amazingly thin and it is easy to worry about doing damage. If one uses a large rubber pad on the jack it should be fine. Yes, an adapter naturally lifts the car more solid and puts the pressures closer to the frame mounts.
The problem with the C7 is the cradles are no longer square, flat, and even. Only the rear portion of the front cradle is flat. Even at the ends of the cradle where the a-arms mount the surfaces are different heights or angled. It would be best to have the car on a lift so the adapter contact points could be fitted to to the cradle.
Despite it being below zero I ran out to the shop and snapped a couple pictures. Those who have not been under their car may find them interesting. This is a Z51 but all the structure is the same on a Z06. Here is a side view of the rear. Notice how nothing is flat or level like previous generations. The probable contact point for an adapter is circled. While this is on the rear section, the frame mount is just above. Gm suggests the center of the front section.
This view shows the shape of the rear cradle. If your OCD the contact point is angled.
About 21" outside edge to outside edge.
The front is more complicated. The rear section is flat for the most part and a support across it would be easiest, but a large rubber pad on the jack would be enough. Trying to lift at the outer edges of the rear section gets difficult as there is no simple contact point. It is a long reach from the front to get the jack to the rear section.
Circled in green is a possible spot for an adapter, it is on the front portion of the cradle next to the a-arm and is supported to the frame.
Again, nothing is flat and even. The front ear is lower then the back but should be fine doing the job by itself.
Outside measurements, just inside of the alignment washers is about 26.5 " I would not construct a lifting adapter without having the car there to custom fit. It just is not as simple as it used to be.

Wow! Thanks for the help. I have an AC jack that has the rubber jack saddle so that may work. Thanks again for the measurements.
For the rear this won't work well will it? might just come collapsing down? Can't put it at the hole area but needs the flat surface instead? But the way my jack stand is it can't get a hold of the flat surface well. (and the same for the front? see 2nd pic) Also I am using quickjack so the jack stands are back ups, so do I need to get the jack stands as close to the jacking points like almost touching, or off by 1,2 inches is ok like in the 2nd pic.
