MG MGF Technical - How about tower strut brace...? Would it be good in MGFs?

Hi, I was wondering, 'what does tower strut brace do?'..
Does it make the car flex not as much as without one? Wouldn't it improve handling on corners..?

I am not too sure on this, but I don't see this would hurt the car if custom installed in the bonnet?

What do you say?

I say this, because maybe adding a strut brace might have less impact on crossmembers -> less cracking..?

I am not too sure, just an idea..

I am sure it won't be too hard to fit other cars braces on MGF.

Please let me know!

Thanks
:)

A good idea on a gravel-spec rally car. Possibly of minor benefit to a circuit race car. On a road car it falls into the same category as a noisy exhausts (with large tailpipes), tinted windows and add-on spoilers.

The MGF cup car has one welded in the rear in the engine compartment, but not, interestingly, between the front suspension towers.

Is this because the subframe takes all the suspension loads? Certainly, the front subframe is substantially stiffened and seam welded...

So I guess not Hanah- except at the rear, the strut brace may be no more than a pleasing aesthetic device as Mike suggests.

but but but.. ;)

you can't even see it without bonnet open! why is it a boy racer item.. i wanna know ^^ (oh that's a smily face by the way)

sure boy racers don't drive it with their bonnet open to show off... :)

Rob, which subframe is that? the cross member that is not welded on properly on mine? :)

But thanks for the msgs!

Hanah, the subframes are sturdy box-section frames to which all the suspension parts are mounted to. There are two- one at the front that also carries (I think) the steering rack and one at the rear that also carries the engine/transmission in addition to providing location to the suspension wishbones.

The equeaky bar on your car is a crossmember that increases the torsional rigidity of the car and improves crash worthiness- not to be mistaken with subframes...

Actually, I had wondered about strut braces as well, but because the suspension design means that very little load (with standard shock absorbers) is transfered to the bodywork upper damper mounts, that I figured it was probably pointless and unnecessary ballast... although some do look rather cool ;o)

Thanks Rob

Explained everything, if you could read my new thread... that would be good thanks!

'cross member update'
Hanah

Hanah - boy racers like to stand around with their bonnets open showing off their strut braces, air filters, colour-coordinated cam covers etc. That's when they're not standing around with the bonnet shut showing off their fake bonnet pins. At least the strut brace might stop bass speaker from shaking the rest of the car to bits...

Not much point in "strut" braces with no struts as suspension components.
