E70 strut brace.
 

Does anyone know where I can find a strut brace for an e70?

Thanks:thumbup:

Why? Underhood jewelery?

or is there some demonstrated need for this?

Not styling, performance.

The X5 frame is very stiff, so any performance benefit would be minimal, even on a track. Even the X5 M doesn't have a strut tower brace.

To answer your question, I don't know of any.

i hear Neon cuts two seconds a lap too. :rofl:

@ X5X, what kit do you have on your avatar?

G-Power

Thanks.

The X5 already has two shock tower braces. They are connected to the firewall. You won't get any better 'performance' connecting the towers to each other.

Anyone?

Given the comments above, why would anyone even make one to offer for sale?

^ hmm, even I have a strut brace in my 3.0si... why isn't this available from the parts dept?

you can also see it in this video: http://www.youtube.com/watch?v=H7FVdXpCz5I

Am I misunderstanding something?

Yes. The E70 doesn't use McPherson struts, but rather a double wishbone front suspension. All a brace would do is tie together the shocks, not the front suspension mounting points, so there is simply no benefit.

Thanks:thumbup:

If there is no added structural benefit, I would not install one if I were you. All you're doing is increasing the potential damage to your X if you get hit in one front fender since the energy would be transmitted to the strut tower on the opposite side.

hmm, what is that bar there for then?

What bar? All I see is a gasket sealing the engine compartment.

Maybe that bar? It's a lot more apparent in the 3.0 engine bay.

I just noticed that my X5 has a chrome strut brace like in the picture above, and one at the front of the engine.

Aluminum. They stopped the black painting about a year ago. Looks better, Nescafe?

The front bar is called the cross car connection (ZB Querverbindung)

The two rear ones are called dome to dash panel struts (dom Stirnwand Strebe)

^ so they are strut braces/bars no?

At great risk to myself in waking my kid when grabbing the keys, I ran out to take these pics:

Thats exactly how my engine bay looks like.

No, they are not strut braces in the traditional sense, because you don't have any struts to brace on an E70. The 'strut' being referred to in strut braces is a McPherson strut, and the top of it (under the dome) locates the suspension. A strut brace running across the vehicle transversely ties the two of them together to maintain front end alignment under extreme cornering loads.

The two short braces are struts in the generic sense of a strut being a horizontal or vertical support member, in the same sense that you have struts holding up the hatchback, but these struts appear to be strengthening the dash panel torsionally, since they are called 'dome to dash panel struts' as Viperfreak posted.

^ thanks, what about the front bar if that is not "maintaining front end alignment" either?

I can see pics of strut/stress bars on a Z4 here: http://www.bavauto.com/lview.asp?img..._99_85_011.jpg ... mounting points are obviously different. Just curious what the point of our bars are.

I am not sure what the front brace is doing specifically, but I imagine it helps stiffen up the front end. That could be for crash impact ratings, to mount some component (like the air duct shown), to stop rattles, or any number of things. Thinking about it, the E70 fenders are totally prefabricated by an outside supplier with the outer and inner fender, lights, etc, before BMW assembles the vehicle, so perhaps this brace just ties together the two fender modules.

The photo you linked shows a silver coloured strut bar. The Z4 actually has struts under those domes, so it makes sense that someone might want to add one. Those triangulated bars look like the X5 dash panel braces, so they are likely doing the same thing, bracing the dash panel.
