There is of course a central structurally sound unapproved jacking location in the middle........but if you get the wrong spot you will potentially damage other stuff.

My car is so low in ride height that I usually jack from the lower control arm hinge near the upright and then get one stand at a time under the rear jacking points. Then go for the central location if needed, to go higher.

I believe I have used the pan toward the edge to support the engine only but I have a Mantis deep sump which is a fairly thick billet aluminum component. If one plans to change transmission mounts is there a recommended support location on the engine / trans.?

...without the use of the support bar?
