we've done sumthing like that...
rear strut bar then from each strut goes to the back wall...
thats more usefully
there sumbody just went to HD and screwed it in
i am goin to do htat to mine... my cousing has his own shop where very little techinical things can be done... so i will let u guys know how it works
looks like crap

Erm. What's that bracing exactly? What is it preventing from flexing?

yeah that wont do crap. its just another honda product that dosnt do anything.

u want real bracing? get a full roll cage.

haha people are stupid, they think anything u just bolt in helps. And im sure everyone will tell u it makes a dif, just to justify them doing it. Like strut tower bars dont even do much, but people sware that they help a ton. like lagos said, u want somthign that will really work, get a roll cage.
i have seen it on an integra type r, but can't figure out what it's really bracing?
but until u have tried it u can't really say.
Didn't you guys see the first one? How it was smashed up from the flex? You don't have to put in a full cage to get results. Little things like that all over the place do help. If things like that (ex. strut tower bars) didn't help, then they wouldn't be a stock item on the higher end sports cars. My point is, any were you get the opportunity to add a brace from something to something in your car, it's going to make it stiffer, it's just a matter of practicality.

Actually bulldog, our cars are unibodie frame, there is no point to these "trunk braces" or whatever the hell it is. I went and talked to my performance guy about them just to see if he's ran into it before.

And for the rest of you, that bar that goes through the floor might actually be bolted onto something under there, but, more than likly, not.

I disagree with what you've said your performance guy said. If he knows what he's talking about, he'd tell you it did something. But, he might know it would do some, but that something is minimal so he just told you it wouldn't do anything. Sometimes the benefits are some minimal that there's no point in saying that there is any, but that doesn't change the fact that it does work. With a combination of a lot of little things such as these to help stiffen the car, you will eventually see results.

I’m not trying to argue with what your performance guy said, I’m just trying to explain why he said it.

Ok theres a big dif between some random bar on the floor where nothing is going to flew to a strut tower bar. Im not saying a strut tower bar will do much, but there is nothing bracing between the up-built structures. Therefor ur going to recive a slit bit of flexing. Where that integra did it, there is nothing that is going to flex. If maybe its holding somthing down underneth, it might help, but i doubt it. U can try it, but im teling u, it will do nothing.
So your saying that bracing does nothing unless it's a cage? I'm not sitting here and saying that that bar is going to make a big difference. I'm saying that it with a combination of other support bars will make a difference. If you want to agrue, at least know were I and you stand.

Bigmeanbulldog55, you cant keep defending an idea that you have no proof about. Its pointless argueing. Yes we understand that bracing in a car will help stiffen the unibody, and in the end will help the suspention geometry stay the same during heavy turning. But that doesnt mean that if i put a big metal pipe in my car, that connects the trunk to the one of the bolts on the passanger side seat will help. i quote "Erm. What's that bracing exactly? What is it preventing from flexing?"
The body does flex. Race cars are commonly spot welded and reinforced throughout the entire "BODY" to reduce flex and weak points in the design. As for the picture... it all depends on the car. You can't really make an argument for or against anything unless you know what car you're talking about. When directly reffering to a Celica body, that brace isn't anything dramatic because there aren't any stress points under it. It's really not bracing a place of significance in terms of body flex... Also, it's not a matter of simply bolting a bar to the floor, as the picture demonstartes, but then again, it heavily depends on the car.

Also... roll cages don't neccesarily reduce body/chassis flex. They aren't called "Roll cages" because they're designed to reduce body flex during hard cornering. That's just silly. Roll cages are to support the body when EXTREME weight reduction is done. It helps reinforce the cockpit so the car doesn't crush like a can during a roll-over. It heavily depends on the cage's design, it's mounting points, etc... Increased rigidity is sorta like a nice side-effect.

Just don't assume anything... and bigmeanbulldog makes perfect sense... so those of you who are bringing up things such as "unibody frames" and "random floor bars" are only following the bandwagon. You can't make such an argument unless you know what those bolts are going. Oh... and don't try to simply blame Hondas either. What's the car got to do with anything?

Kwanza they should change ur name on this site to --- "the truuthh" yes with two uu and hh ...

but yea like he said... it really depends on the car... way back when i had my A4 ... my dad welded a bar in the trunkbed that had bolts sticking down to under the car.... really don't know what the hell that was for.. but he said don't worry about that.. it's will give u more girp to the RW ... when i finish the rest of it...

Which is why I asked what it's supposed to be bracing.

And as for rear tower braces......
i took mine out for a short trip to get a large load in the trunk fo my '4' and i could feel what it was for, it went straght bad.....

Life is for living, and you don't get a second chanceTake care now !!
well... i don't think that's useful and not really a nice looking bar... i'll post a pic of my Jspeed rear strut brace that i installed yesterday nite. works really well for me >biggrin.gif>
