I just talked to the guy who installed a J's Racing Rear Pilar Bar on his DC2 today, and here is a updated review on how he think of the bar.

"I have driven around for around 200km since I installed the rear pillar bar, and I think it definitely worth the money so far. You wouldn't able to feel the difference at all from normal driving around town, similar to the front and rear strut bar. However, when I tried to take some hard corner, I can definitely feel the chassis is stiffer with the bar installed. It is really difficult to describe exactly on how I can feel the difference, but it defintely just feel alot better. I can't wait to see how much difference it will make on the track and auto-x.


The install of the bar was really simple, I think I can do it myself in like 20 mins. The bar just bolted onto the rear seat seatbelt, and the rear seatbelts remain functional after the bar installed.

However, there is also a few downside for this bar. 1) Most obvious is that my car will become a 2 seaters in the future. You can still sit in the back, but it is not very comfortable (ITR rear seats are not that comfortable to begin with), also I don't think it is safe to do so. 2) You will need a day or two to get use to seeing the bar from the rear view mirror, because it is in the way for sure.

But to me, my car usually only carry me and my girlfriend around, so 1) wasn't really a problem, plus it didn't take too long to uninstall the bar if necessary. (probably around 15-20 mins if I do it myself.). "

I just quoted what the guy told me, and I just want to share with the ppl here. Here is the picture of the bar installed again.

I'm sorry but this still sounds like an ad.

If you wanted to make it clear it wasn't an ad, you could have left out the sig.

If anyone wants this J's Racing bar, I recommend buying it from AJ Racing, IPS Racing, or R&D Motorsports.

I find it VERY hard to believe that he could tell a difference by installing this bar alone in an ITR.

 

If anyone wants to get this bar for an awesome price, check my sig.

 

tell us how! tell us how b2ner?!>!?

 

Some ppl told me they can feel the difference when they take out the stock ITR front strut bar and install the Spoon strut bar too.

I am sure it is easier to feel the difference made by the pillar bar, since the stock ITR didn't have one to begin with.

I just quoted what I was told by the guy who have this bar, nothing more and nothing less.

Where's my signature ?

 

This bar I would say does make a minimal difference, but a little here and a little there adds up! Just like how Spoon does a little mod here and a little weight saving here and there just to shave that extra .00001 sec off.
Have had great customer service from BPT before, you can check with Mafay2 to hook you up with deals for sure!

 

What sig. ?

 

If you work at BPT, can you tell them to do something about the website. It is one of the most annoying sites to visit. Flash websites suck most of the time. Too much animation and moving and intros etc etc.

Maybe they could spend more time adding product info and less time on dancing logos. It was cool the first time, but on return visits (and I went back just now hoping to see something new or different) it is horrible.

I would consider purchasing something if I could see some parts and prices. Since we all like to window shop. I hate having to call and ask if you have something and what it costs.

 

my friend has that bar in his eg and he said he could tell right away the body of the car doens't flex anymore. i think i'm gong to pick one up pretty soon. i don't feel like carrying anymore passengers. i already have the seats out. might as well keep it that way huh? ehehe

 

A USDM Civic hatchback and an ITR do not have the same structural integrity so the difference might not be as noticeable.

Also an ITR has more structural braces to begin with, bringing in the law of diminishing returns.

 

get a rollbar,

that is where it's at...

u already dont have ur rear seats...

 

No doubt.

I really gotta wonder too.....where'd this freaky bar get developed....in a race shop or a marketing dept? How can it do anything worthwhile for handling? Is it just me or shouldn't it tie into the suspension in some way, to be of value? A car's suspension is where the forces of nature are fought. The car wants to lean and the suspension fights that. If it wants to flex between those points, the tower bars brace those points. Also, the towers are a point of strength; a good place to mount a bar that gets stressed. And once the bottom is braced, the top just rides up there, as there are no points of stress on the top portion of a car.....unless you roll it I guess.

I dunno, just call me skeptical, but I don't think one needs to be a suspension engineer to think this one through. But hey, if someone has proof otherwise, please give me a clue, otherwise don't get played by the mkting dept.

 

If you take a hard right hander (90 deg or more), the frame of the car twists in the center (passenger compartment) as the inertial load causes the front left tire to dive (body roll) and grip, which lifts the rear right tire. i think the pillar bar smooths out the transition from light understeer to controllable oversteer without allowing as much lift on the rear right wheel by stopping the twist of the frame in the middle of the car. based on that hypothesis, i'd assume those of us with sunroofs would benefit a hell of a lot more from it, as it would compensate for the gaping hole in the roof. A type R already has structural reinforcements, and doesn't have a sunroof, so perhaps the benefit would not be as immediately apparent.

I think what the pillar bar do is to stiffen up the chassis. Does it make a huge difference, I would say NO, but it certainly help stiffen up the chassis. The effectiveness may be difference on difference car, because the structural design of each car is difference.

And for sure, a rollbar would be a better way to stiffen up the chassis, but for those ppl that don't want a rollbar in their daily drive, this would certainly help a little bit.

As for the website thing, I don't think it should be discuss here, but for sure I will let the web-designer know about it. Thanks for the comment.

couldn't have said it better

 

Bullshit - this is placebo effect - nothing more.

To truly determine whether you can feel a difference you would have to do a double-blind statistical test (i.e. driver drives car several times - sometimes with bar - sometimes without - but the driver doesn't know when - you would have to hide the rear of the car from the driver somehow).

For the chassis flex analyzers - your logic is correct but you cannot make assumptions without hard proof. You need to conduct Finite Element Analysis of the chassis to make any concrete statements regarding chassis flex changes.

This bar mounts to one of the most SOLID areas of the unibody. This area (C pillar) is also not directly loaded by the suspension in any way shape or form.

Bullshit I say.

 

Speaking of which...

If someone can give me a model file of the DC2/DC2R chassis I will pay you mucho $. As far as I know this is pretty much unobtainable, and would take FOREVER to start from scratch.

Any info appreciated, I would FEA the **** out of that.

 

I have the J's Pillar bar and I think it makes an excellent camera mount. Does a little for body rigidity.

I would be more interested in getting something like this myself:

 

Now we're talking. How much is this bad boy?

 

WTF is that??

 

Its by a japanese company called Next. Its called the MONSTER CROSS BAR

Interesting...
