Well, this dude is not an engineer - clearly.
IF you brace an area that was previously PLAIN AIR - you WILL have an effect. It's just a question of how much & if you will notice it as a driver.

Don't listen to fools.
I don't really understand what you're saying here. :?

From what I understand, the quoted statement is that BMW have provided the required bracing with the standard diagonal brace set up. We know the chassis is already very stiff.

So I don't know the answer to this but I'm reading into this that BMW M Engineers felt the level of bracing was correct for the cars application. Now of course you can continue to stiffen, but the question would be would that improve things or actually detract from the handling set up?

I would think a strut brace would be a low cost item for BMW to fit if they thought they needed it, but then would it the case that the standard set up is fine for road use but if you are tracking the car regularly or want the extra bracing to sharpen the front even more at the expense of some compliance then you add a brace aftermarket etc?

The plain air being over the top of the engine. As a result the turrets will be braced more now they are connected together and back to the firewall.

Correct.
And, BMW themselves sold the brace as OEM accessory.
It just wasn't vital enough to put on every car they made, they saved that cost (not negligable).

BMW also considered Contisport M3 tyres suitable for the Z4M as they’d been fine on the M3.
But they never seemed to work as well on the Z4.

They also signed off the terrible suspension.

Shows they don’t know everything.
Agreed! moreover, everything is a compromise between cost and benefit: I am inclined to think that sorting out the suspension set up was going to cost a lot of money and would have driven the price of the Z4M up too far.

I was following this thread with interest. Here’s the one I’ve invested in :)
I’ve yet to drive it, but I can see how it will be stiffer than the tubular ones. I reserve judgement on the handling improvement until I’ve driven it, but I do like the look of it if nothing else 😂

Of course, the coupe is stiffer overall but the front end is the same as the roadster :thumbsup:
