Has anybody ever tried to make their own trunkbar?

Well i have and i think that i noticed a difference in the cars' behavior. It seems like its more predictable and wants to react faster, but it may just be the placebo effect so it may all be in my head.

Does anybody know what kind of stress these there things experience. If its more like a lateral stress where it wants to stretch then i think that it may work out pretty well. But if it sees any type of vertical stress then i have a feeling that it just bends.
It is pretty stiff on the other hand. I can shake the whole back of the car around without any flex at all.

Here are some pics of it. Its pretty cheap looking but i did make it myself. It also cost me about 6.50 to make the damn thing so i wont be bitter if it really doesnt work

 

what kind of joints did you use to thread through, can you give us a few more specs and a more involved DIY

 

i didnt use any joints

There are holes that are there from the factory

All i did was find bolts that would thread into the factory holes and drilled holes through the pipe. After that i torqued them down pretty well.

Its like i said, pretty cheap and roughly done.

 

Retracted

 

The EVO RS comes with trunk bar and my buddy has one and it makes a big difference in rear stability. The bolts are there for a reason. Cusco sales a trunk bar.

 

This is one rigidity modification that is reported to make a considerable difference...

 

I tihnk its designed to reduce flex in the truck floor pan... since there really is nothing securing the back end of the car together.. Only thing we might have is a rear strut tower brace but that doesn't tie the floor pan together... I know on 240's they have a sort of cross member that bolts behind the driver and passenger to help tie the subframe together and reduce some more flex...

My 2 cents... I tihnk it worksand serves a purpose, but then again it will only work as well as its designed to... so hopefully your bar will work (not trying to say anything negative)

 

lol thats cool

I was just bored one day and tried it out

hasnt done any bad and it weighs less than a pound, i think ill keep it

 

just to add a note.. if it flexing... its not doing anything so make sure its very very solid.

 

its not flexing at all

 

Anyone have this bar and a rear strut tower bar? I'd like to know which bar makes more difference.

 

I installed one made from 1x0.5 aluminum bar stock. After I bolted it down and pulled up on it (I'm a 250lb ape), I noticed that the floor pan would flex (the bolts are just tack welded to the other side of the sheet metal). I can easily see the bolts pulling out, or cracking the sheet metal over time without some backing plates installed on the other side. Some may disagree, but I took mine off until I feel like pulling the bumper to do it right.

 

I think that you will find that the nuts are tacked into the box rails, and they are thicker than you might think at first.

 

I really hope the "box rails" do not have that much give... the whole car would wallow down the road if that were the case. Maybe I'm just "meaner" than I thought.

 

Well I looked under the car and that is where the bolts come out.
