I've often seen pictures posted by CZCC members where their Z is perched up on axle stands, front and rear. Getting a car up on stands at either the front or the rear is easy. I'm curious to know what the accepted wisdom is for getting the other end elevated and then getting the stands extended to full lift. Can it be done safely in one step, or is it better to start with the axle stands at minimum extension and then go back and forth in steps from front to rear until both ends are up all the way (i.e. the axle stands at maximum extension)?

Good topic. My thinking is that it's better to go in a few incremental steps, going front to back. This method minimizes subjecting the jack stands to axial (horizontal) loads. The rating on jack stands in only for pure vertical loads.

It is safer to go back and forth; setting one end low before jacking the other end high and going back to raise the lower.

Does anyone know of / recommend stands that support the car on the lug studs with the wheels off?

I've used common jackstands for years. )n the 280ZX in both front and rear there are obvious places which can support jackstands. In the rear, I slide a floor jack under the differential, lift on it and place jackstands under the places in front of the axle where the suspension bolts to the underbody. it's not hard to find stout places that can support the stands. What the factory manual says aren't the only places you can support the car if you're thoughtful about it.

In front on my 280ZX, I slide the floor jack under the cross beam beneath the engine, then position the jackstands under the stoutest place in the frame rails with a chunk of 2x4 on top of each jackstand to spread the weight out.

On my 280ZX I jack up the front first, then the back. It's low enough that getting much of an angle on either end makes it hard to access the other end. you may have to slide the jack in from the side, not the front or back.

Lift carefully. Push on the car and make sure it's stable. Push on it after the jackstands are in place, and double-confirm that it's stable. Patience and thought will yield a safe result.
