The fact that BMWs own factory repair manuals show it as a safe lifting point means more to me than hearsay on the internet. You'll notice its very explicit about having to remove the metal under tray from the rear before using the rear diff as a lifting point. No such qualifications made about anything at the front.

That's a fair point, can see the arguments on both sides

Obviously just do what you're comfortable with, as I said I've used the centre point multiple times with zero issues, albeit I don't have a jack that can reach it without lifting the front wheels a bit anyway... massive pain!

Typically use the side jack points to lift the front wheels and putting a block of wood under the wheel, dropping down and swapping sides before finally getting to the front centre point and stands under the side pads. Used to be able to use a ramp, but the splitter on the car has done away with them plans

To solve this issue entirely could always invest in a quickjack. Used mine for the first time last week wish I would've gotten it a long time ago.

Take care the document you linked to is NOT a BMW factory repair manual at all!, on the home page it says "newTIS.info is not an official source of information and is not affiliated with BMW in any way". Its wrong and is showing a schematic of of the ///M which has jacking point access, the rest of the range don't. If you check any manual supplied with a non-M car the front point is not a safe jacking point because it's a light alloy honeycomb brace that will crush and will lose it's structural integrity.

Firstly, I am not saying you are wrong Ewazix however the car shown underneath has only two exhausts so can’t be an M however I totally agree with what you are saying reference jacking points and crushing things, just too risky in my book. I’ll stick to the side jacking points and awkward it may be but it’s safe.

Could an M brace be fitted to a non M car to facilitate a jacking point?

TIS (Technical Information System) is BMW's official factory repair manuals. This website is merely an unofficial hosting of it as BMW don't officially release it to anyone outside the dealer chain, hence the website stating they are not affiliated.

I can open up the official BMW TIS software on my pc and it's the exact same. Unfortunately I can't very well link the software on here for every question.

Please do some research before jumping on people's comments and preaching "hearsay" as factual information. Do you honestly believe the subframe of a steel chassis car is lightweight honeycomb aluminium?

Never mind 'research' or 'preachy hearsay' you cheeky sod, I happen to believe it's hollow alloy because I've removed it!

The part we are beefing about is called a front suspension reinforcing plate (the clue to its function is in the name) it's there to add lateral rigidity to the front suspension (stop it slopping about) and people who have driven without it report the car feeling strangely wallowy on the front end. It's part number 51717028433 (shared with the E46 and E86) and is made of hollow, reinforced aluminium alloy. Because it's there to provide lateral stiffness only, and is light alloy hollow section with some lattice reinforcement inside, crushing it or deforming it's lateral strength or dimensions will risk unwanted suspension 'slop'. It's not designed to be used as a jacking point, if you remove it, then yes you will have a jacking point underneath per the ///M, which may explain why some diagrams show it.

In fairness members say they have used it and found that crushing this member hasn't caused there car to collapse or crash in a ball of flames, so maybe crack on

Seems we have a misunderstanding here. I was not advocating using the aluminium plate as a lifting point, bit the cutout on them fits a jacking adaptor perfectly and is positioned directly against the structural cross member behind. Perhaps you missed my earlier point about it not doing any damage or bending anything using the correct jacking pad.

So this part is lightweight hollow aluminium and I wasn't trotting out 'hearsay' then?

The area under the indent is still a cavity, pad or no pad I can't see how it will not crush. People who have done it report it crushing even with a pad, which is why I didn't try. It sounds like you have actually done this? If you get a chance a video of how you use a pad on the alloy member would be a really useful for members thinking of using what would be a great facility.

related question to this thread,

my reinforcement plate does NOT have the rubber jack pad, and I cannot find the part number on Real OEM (maybe I'm just not seeing it).
Does anyone know that part number?

2006 E85 3.0si

Here is a pic of what I am referencing...

Because it's only fitted to the M you won't find it if you're looking at realoem under a 3.0si

Migizi · Post by **Migizi** » Sat Apr 13, 2019 2:20 pm

would the rubber jack pad for the M fit on a non-M?

No, the front axle assembly including the alloy reinforcing plate are different part numbers on the M. The reinforcing plate of the M is a different construction and also has a cut-out for the jack pad. You can see the assembly and part numbers on real oem, unfortunately the non-M cars don't have the cut out through the hollow section for a pad.

But looking at the two they both are fitted with 8 x M10x35mm bolts so wonder if the complete M reinforcing plate with it's cut-out and pad can be fitted to other models?
