Custom Lightweight Bumper Beam. (pictures)
�
�
This mod is intended for individual wanting weight reduction for their cars, this mod does not meet safety standards and will not protect your engine bay as much in you were to have a front end colision.
I have just completed my custom light weight bumper beam for my 2006 WRX. I am trying to reduce as much weight as possible on my WRX, i am not sure how much the stock bumper beam+foam weighs but it felt like it was 50lb, the thing is massive. I went to Home Depot and i bought a 4' long squared hallow iron tube to replace my stock beam, i measured the 4 top holes and i drilled onto the light replacement beam (Home Depot beam must weigh around 7lb max). The only reason i am putting this lightweight beam rather then just riding without anything is to keep the car rigid as much as possible, safety wise is not going to help me much at all but i still keep the stock rigidity. By doing this mod you will reduce weight and you will also get much better air flow to your radiator, when stock beam+foam is removed it frees up alot of space between the radiator and the bumper. It torned out very good and clean, see pictures bellow.
Here is what you need to do this mod:
1) 4 feet long 1 inch wide squared hollow metal/iron tube. You can find that at Home Depot, hardware section.
2) you will need to measure the top four holes on inside of stock bumper then
drill it on to the new bar, measure the hole on the inside of stock bumper and make same size hole, drill one side on the new bar only, the opposite side you need to drill bigger holes so that you can fit a 14mm socket trough in order to tighten the bar to the chase.
3) you will need move the two horns around to accomodate the new beam, not a big deal though, just losen the bolts and move the horn up so that you can fit the new bar.
All of this will make more cense once you have the front bumper out and the front beam out.
Post any question you might have. Good luck

your front end will be completely distroyed if you get in an accident though :(
I also imagine insurance companies wont like this if you get in an accident and they see it going through the damage.
It just seems really risky, but is this the same thing people have to do with FMIC's?

why have one at all? <i read ur post; dno't know if rigidity is affected by a crash protection device... much like the crossbars in the back seat> i figure you should only use one if you have a front mount, otherwise i would keep mine there.

and actually most fmic's come with aftermarket beams... my aps did, the txs one comes with a REALLY flimsy one... that's what the fmic bolts on to.

rigidity for cornering and hard driving not as a "crash protection device". i know if i get into a head on colission i will get more damage than if i had the stock front beam but hopefully i will not get into an accident at all :) .

I was just saying that I thought hte bumper beam had NOTHING to do with body stabilizing and everything to do with crash protection. Have their been results or anything like that to state that the bumper beam is smoewhat of a stabilizer bar?

It's your car to do as you please with, but bear in mind that there is a reason they call them "accidents"- you never plan them.
Having seen firsthand what a minor impact does to the factory beam, I would never consider removing or modifying it. Because of the strength and design of the beam I only needed a new bumper cover and the beam itself, without it things would have been very different.

i am not sertain that it does have anything to do with stability but if you think about it, the bar i put would have kind of the same effect of a strut bar. I understand what you are saying and i think it would only benefit me by putting that bar there for rigidity purpose.

I am completely aware of the consequenses if i was to get into an accident, that is not the point though, this thread is for weight reduction purposes, if you want to go this route is up to you, i stated thes risk on this mod on post #1.

do you know how much the bumper beam effects torsional rigidity? do you know when and why torsional rigidity is important? You are better off with nothing there at all. In any impact over 1000N that thing is going to be bent up badly. so basically don't get in anything over a 5 mph impact or you'll be left with an impretzle.

This thread is intended to give the individual looking to buy a jdm bumper beam or looking to reduce wight another option of doing it themselfs, a much cheaper option.

Once again, i am aware of the consequesces and again i will say that i didnt do this mod thinking of safety. in my mind Most people using front mount intercooler would be just as vonorable as me, they eather buy a JDM bumper, modify the stock beam or they just dont use anything.

this was right there in the beginning of the thread. I am pretty sure that he understands the consequences of not using the oe bumper beam on the roads. but he only made the thread to show how to save some weight not to show you how to make sure you kill yourself next time your in an accident.
by the way balex5884 good idea

These threads are poping up everywhere now! People modifying safety devices and the mass numbers of posts telling them how wrong they are. Its getting pretty out of hand IMO. I have a JDM lightweight bumper beam, I removed the heaping hunk of dead metal in my center console. I'm probably not going to die from these. NEW RULE: IF ITS ALREADY MENTIONED THAT THE CARS STRUCTURAL INTEGRITY IS COMPROMISED DON'T POST AGAIN. Chances are what your about to say has already been said eleventy billion times.

I didn't say he would die... I could care less. People's points are not dying... it's front crash protection. If you get into a 10 mph fender bender, your new bumper beam is your engine... you knock your timing assembly and your valves interfere with each other and possibly your pistons. That's obviously not even worst case because a slightly tap on the cam gears could do that. Anyway, I'm in the same boat cuz I have a front mount. I'm just saying... I see NO point in doing it unless you have a front mount. I do appreciate his write-up, as it's well written, detailed, and he did a good job.

Another thing is that factory JDM bumper beam still utilizes a foam absorber. This means you won't need to replace the bumper cover (and possibly the headlights) in a 5 mph crash. I guess there is some assurance that the Subaru engineers knew what they were doing when they purposefully designed that. So, your beam has nothing to fill the void under the cover whereas even a front mount intercooler would.
What about the rear bumper beam?

I totally agree. I have a Turbo XS FMIC with that flimsy aluminum "bumper beam" that came with the kit, or more like a "FMIC mounting bracket." The point is that FMIC is on there, and it's on there damn good I made sure. That FMIC serves as the bumper beam, well kinda. It's much better than the rod you have. The FMIC will absorb the impact the bumper beam would normally absorb, granted the stocker covers more area of the front end though, but you get my point.
bottom line...go get you a FMIC and then use your bar w/ the FMIC if it will fit...that will offer so-so protection.

A few clarifications I think are needed. The IIHS (insurance company) conducts a low speed test- this is a monetary test not a safety test, the NHTSA does not carry out such a test. The IIHS conducts a low speed bumper crash test that the government does not. While these tests don't really assess safety, they can be of interest to consumers in that ratings are assigned based on the costs to repair the vehicle. In this test, the vehicle is crashed four separate times at 5 mph � both front and rear bumpers into a flat barrier, the front bumper into an angle barrier and the rear bumper into a short pole. Ratings are then given on the usual "Good" to "Poor" scale based on repair costs, which often come in at over $1,000.
Japan does their own safety testing- very similar to the NHTSA testing, don't know if they have a low speed bumper test done by anyone however.
The oe beam doesn't weigh 50 lbs (feels like it though) :)- it weighs ~ 28 lbs, the jdm one 13 lbs.

BTW Japan doesn't use any beam at all in the rear on GD/GG models- the earlier jdm GC/GF's have a lightweight beam.
