School me on Strut Braces. Hard cornering or hard parking?

My ZX2SR showed no noticeable difference,  however since I had the chassis mounting holes slotted, I looked at is as a security from  slippage.

On some cars, a lower brace might be more helpfull to prevent toe change.

 Then again,  The idea that ,"I did it so it has to make a difference."     Sort of like the Butt Dyno.

Simple strut braces are not configured to resist chassis deflections from a strut suspension. Forces on the chassis are mainly vertical and a horizontal bar does nothing to resolve them. 

 

I believe we had this discussion in the earlier thread.

Yes,the song is the same and so are the facts.

I don't sell tower brace bars, so I have no reason to be other than truthful.

I also don't sell brace bars, but that doesn't mean I have special insight into how effective they are. Have you done any measurements? All we have is your blanket statements with nothing to back them up.

The Elantra and Forte made no difference. Most of that due to the strut towers being part of the firewall so theres not movement there. I did multiple tests and could never find a difference in actual lap times.  With both of those, there is a complete boxed subframe that the engine and suspension bolt to making it really stiff right out of the box. 

The swift needed every brace I could find. That chassis (And maybe it was just mine) was so floppy. steering improved with both upper and lower braces, upper mounted in 3 points. 

So basically there's no one answer for all vehicles.

In my 924s. There was a noticeable improvement on turn in and consistency of how the front suspension worked. However the one I have is custom made and triangulated off the frame rails on both sides of the motor as well as being bolted to the top of the strut towers. So it is mounted in four locations.

Not to mention insulting a well-respected vendor who provides plenty of data and testing for the parts they sell.

At this point i think the big key is what chassis it's applied to. But with that being said, as long as the weight of the bar isnt an issue (they are usually no more then a few pounds), then a strut tower bar in any form, hinged or solid, isnt going to make a car worse. so if you are compelled to get one, i say go for it.

My guess is the most important thing a strut bar does is resists the tension force created when the outside wheel in a corner pushes the bottom of the strut in and the top out. The strut bar allows the inside wheel strut top (that wheel is not forcing on its strut quite as much) to help resist the rolling of the outside tire to worse camber angles. I'd further guess that the biggest improvement from a strut bar comes on cars with poor camber curves, low static camber alignments, and not much castor. It's biggest benefit being just keeping the dang outside front tire from folding all the way over.

I had once tried to work out the stresses on a strut bar and concluded most of them would likely have been loaded in tension when cornering, and generally would not be loaded in compression unless there was something very odd going on. (This assumes it's just tied to the strut towers and not the firewall.)

That's all you have from anyone. Have you any measurements? Post 'em up. If you look at what Porsche and BMW and some others have on their factory race cars you might get a clue, or maybe not.

Sure, but who TF are you? Keith is known as a thoughtful, intelligent person in these parts that does good - no - great work and his opinions hold weight. You stroll in and say, "this is how it is, and you're a shill that's only claiming otherwise because you make money off this." Can you see how that might be offputting? And how there's absolutely no way I or most people would take your input as valuable if it's phrased that way?

Keith provides opinion backed by experience. You provide opinion without any backing info and with a side dose of rudeness.

aaaaand its gone - that thing is cool!
