Safejacks Rennstands with custom Gen 3 "pinch weld" adapters

This is where it bears:



And even on the back end, when using the scissor jack once (with a flat), it pushed in some.

I've never had the urge to raise one side of the car. I either do the full front or full rear. If I'm rotating tires I do both. Safety stands front or rear I place on locations near those scissor jack points, but much more substantial. I've done this countless times now, with both oil changes and tire swaps twice per year. the points I use, and they're fine with typical safety stand cradles as-is:

 

Maybe not with what you've fab'd, more surface area. I know with the scissor jack, it dimples a bit. Again this was on the rear; the front jack point is maybe 50% heavier.

For the rest, I'll respectively argue the safety stand points I use are very solid. I do jack only at the proscribed front/rear points.

I believe the rear trailing arm hinge point is some distance back from the point I marked. You can see an oval slot both sides, that's for locking pins during shipping. Very solid, heavy guage, and double layers.

The front points I marked are at the leading end of the main beams that run the length of the underside. I believe it was hobbit that identified those points as good with second gen, and I found 3rd gen had similar structure.

 

Those are neat looking stands. I still feel uneasy seeing them used to lift one side of a car instead of one axle. Old habit I guess.

 

I just use some hockey pucks on both the jack and jack stands to protect the jack points. No muss, no fuss...

 

These work too:

 

I think Ray meant "in place of the hockey puck on the jack cup" without any reference to your stands.

At least that's how I read it, and the round contour looks like it would self-center nicely in the dish of most rolling floor jacks.

 

For a counterpoint to Toyota's "skinny knife edge with two notches":

Alll the Honda's I've seen have similar scissor jack locations, BUT the pinch seam material is thicker, and there's an extra, heavier gauge plate reinforcement at the jacking point, about 3" wide. It projects down slightly more than the regular pinched seam, and then has a horizontal leg toeing inward, creating a flange maybe 3/8" wide. Those I have no qualms resting on safety stand cradles.
