Jack Stand Support Locations, etc.

Well done Liam22. Works like a dream.

Before this method I used a piece of wood along the underneath of the sill. The plastic is bolted to the subframe. However I had to Jack the car up 4 times at each corner. The above method is much quicker. The price was for a 3m length that I had cut in half. It’s also a perfect size. I’ll post some photos the next time I have m6 Z up.

Nobody else hangs a front wheel out over a ditch and jumps up and down on the bonnet? :?

 

[Bombardino]

Excuse my ignorance, I assume when you said lift from the middle you was lifting either the 2 front or the 2 back wheels, I’m totally onboard now.
Ironically I only watched this video the other day : https://youtu.be/LV_HdyFuc64

That’s what gave me the idea. Simply joins the jack pads.

So does it stay in place ok?
Would it be worth a mod (add a lump at the ends) so it locates firmly in the jacking points?
And taking that a step further, maybe a way to locate the axle stands more securely underneath the bar?
Probably over engineering, but..................

Depending on whether you use a piece of wood or steel it needs to be small enough to fit between the 2 jacking points as the video shows.

Ah, ok, can't watch the video at work.
I misread and thought it fitted at both jacking pads and put the load through them, hence me wondering if it could be more firmly located in them.

I'm not liking the idea of lifting on the sill even with a spreader on a seam per the video, you can clearly see the spreader bow leaving the weight on a relatively small spot, not worth the risk IMHO.

Which is why I was thinking you locate the bar in the jack points to take the weight.
Then make sure the axle stands locate securely under the bar.

The thing that throws me off about the picture showing the front centre jack point is that it's a non M in the picture, there's only a single exit exhaust.

 

[Woodrow]

Yes. I don’t touch the sill with the bar. The bar connects to the Jacking points.

 

[z4pilot]

Yes. I don’t touch the sill with the bar. The bar connects to the Jacking points.

Does that not crush the plastic jacking point guides?

 

[enuff_zed]

Yes. I don’t touch the sill with the bar. The bar connects to the Jacking points.

Does that not crush the plastic jacking point guides?

Which brings me back around (yes, again) to my theory of creating a bar that has the equivalent of the jacking pad adaptors somehow recreated on top of it, to make sure the load is correctly applied as intended by BMW.

Now I’m really confused, how can you possibly lift the car using the jacking points & use the same jacking point for the axle stands.

I don't think he does? (Waits to be corrected...............)
By my understanding, the bar stays in place and the axle stands go under that?
Which is why I thought it would be a good idea to put something under the bar, in line with the jacking points, to locate the axle stands.
In principle the creation of a bespoke bar like this sounds a cunning plan.
Wish I had the facilities to produce them.
I guess the next question is, are the jacking points the same distance apart on E85 and E89?

That makes more sense, if so wouldn’t be to hard to fabricate & would work

Busy day at work, so had a play with my idea.
Apologies to Woodrow, not intending to steal your idea, just thinking on an improved version.

Looks good, how much you charging

Well done enuf. I was just about to draw that on a wall before I painted it.
