Default Does A Upper Strut Bar Make Difference?

There's an upper strut bar that is for sale dirt cheap around here, I was wondering if they even make difference. What are your inputs on them? Should I go for it?

Thanks

Honestly, I think the stock Integra/99-00Si ones work the best for the front. In general though, they do work.

They keep the suspension geometry in check under hard cornering load and provide better response out of the front of the car. The same goes for the rear also.


I say do it!

Yes any bar pretty much will help.... think about it.... its holding the two towers together so that during turning it wont flex therfore keeping the chassis stiffer.

So would one fit over the D16y7 intake? I just went outside and it looks the intake is a bit high. :S Would I have to swap in a Si manifold?

Rear upper strut bars have a extremely more noticable difference than front upper bars.

strut bars really help cornering. i would look into them i picked up one from a friend for around 30 bucks and i really noticed a difference.

Rumor is that Comptech says that a rear upper does nothing for a Civic. I don't know how I feel about it personally. I will say that strut tower braces make a whole world more difference on mcpherson strut cars than they do on the 4th - 6th gen Civic's double wishbone suspension. If you're serious about chassis stiffness, get an autopower partial roll cage and add on to it later.

Exactly right. The rear attachment points for the so-called "strut bars" aren't strut towers. They are just mounting points for the shocks. There's no contol arm there that take the load from turning.

The fronts however can benefit from a strut bar since you have the upper control arms attached there.

YES IT WILL FIT. You dont need to swap manifolds etc..

I've had a Neuspeed bar on my car for years. It fit over the Y7 vertical intake manifold. It was pretty cheap and *seemed* to make the car more stable at highway speeds. I have no idea if this was all in my mind or what, but that's just how I see it.

exaclty. the Autopower partial cage is going to stiff your chassis so much it won't even be funny(lol). they aren't terribly expensive either and they can be added onto at any time.

Jacking up the car will unload the chassis, and make it easier to put the bar on.

-- I have been trying to put it on, and yes it is the right way. I have tried putting it on while the car is on the ground and also while the car is jacked up. I have no clue why it is not fitting properly? Any other suggestions?

It will go on, just keep at it. Jack up just one side if you have to. Set it down perfectly flat and push down on both sides evenly. Some idiots here will actually tell you that the Civic chassis is stiff. I don't know who started such an idiotic rumor but the fact that your chassis flexes so much that when you remove a strut bar, it wont fit back on is proof enough.

I have the autopower, a front upper, a rear lower. But despite what Comptech is rumored to say, I've tried the removing my skunk2 rear upper and then reattaching it and I swear I can feel a difference. I really would like to remove it for weight and then sell it, but I can't bring myself to since I swear it's doing something even with the partial roll cage. Maybe more so because of the rollcage. Then I take a look at rally cars and I notice that they have a strut bar incorporated into the cage.

There is in fact cornering load placed on the rear upper strut towers. If not, then please explain to me what is compressing the strut and spring? Wishful thinking? If this area is flexible, then there will be a slight delay before the strut and spring take effect.

Can anyone direct me to Comptech's statement or test results for Civic Integra regarding the rear upper strut bar? They haven't published anything, right?

A rear strut bar will do a great deal for 7th gen and newer Civics and the RSX, since these cars utilize the inferior mcpherson strut design which does in fact rely on the strut towers as a load bearing suspension mounting point.
