    Default Evo 8 and 9 weight reduction thread

    Special thanks has to go out to David Buschur for adding a great deal of info to this weight reduction thread. this is what brings a great community together.

    We all know the evo 8 and 9 weigh a lot. Most of us would like to lighten them up a little bit. So post up your mods you have done to reduce the weight of your evo. Cutting the car up is not allowed here.

    There are many mods we can buy that reduce the weight of the evo. There is also many freebie mods we can do to also reduce the weight of the evo. With that said lets make an official thread with what was done and how much was saved on your evo.


    The Rules:

    1. Post up what you have done for freebie weight reduction with just a little write up on how you did it and I will add your post # next to the mod on the list for others to use as a how to and better searching.

    2. Post up what you have purchased that was either weight reduction related or just a part that was lighter then stock. PLEASE try and get the full weight of the stock part that was replaced for a better comparison

    3. Last and most important how much lighter was your modification whether it was a freebie or a purchased part.


    I have made a list below for all to view as we gather info. I will update it regularly as long as it was a legit mod and something we all can do

    Lots of information here. I question the weight of CBRD rad.because it saves more weight than the half sized and is less money and would cool better.He is also talking about the new half size which will even save more.I know your also interested will have to keep getting on him. If the weights are correct that would be a lot of weight off the front when you combine it with ac removal.

    I have a HUGE list of parts and such we've weighed and compared. I will contribute to this tomorrow Dan. We might add this to a FAQ section later, can I get you to put my weight saving list in with your first post? Just hit with me with a little credit for some of it?

    I'll submit tomorrow.

    LOL! "Secret carbon fiber?" Nice! I'm looking at doing my driveshaft at some point over the winter, probably AWD's aluminum one.

    Why is removing the front and rear bumper support NOT RECOMMENDED???

    The only reason it should not be recommended is for insurance reasons, as insurance companies may deny claims if you dont have one.

    Safety wise, the crash beam is only rated up to 5MPH. They are only on US cars because of insurance companies. JDM and all other market EVOs dont have them.

    The "not recommended" is for safety reasons. On evom posting taking those parts out was always met with multiple comments about "oh my, it's not safe to do that, I'd never consider it, blah, blah blah" Probably not needed to list it as not recommended here

    Yeah probably dont need to list it here.

    EDIT - Also great thread. I loved your weight reduction page on BR, and this is like an expanded edition.

    I already have about 125 off of my 04 RS and car is still complete interior (except for headliner, as it was missing when I bought the car and is hard to find/ get shipped to me. Any one got a RS headliner there willing to ship??)

    Using a BR cat-back. I love the light weight, maximized flow design.

    I have a question which i searched bt haven't found the answer.

    The Evos have door beams right? Somewhere I read that on the 03-05 cars the door beams weight a total of 40 lbs.

    What about the 06 evo ix? Do we have a definite answer? Do they weight the same?

    And the second part of my question: are they bolted on the doors or welded? In other words, can someone remove them easily or does it require cutting wheels, etc?

    Rear speakers drops 8.8 lbs
    Are you guys sure about this? I weighed the stock speakers over the summer. The ones in my IX (paper w/wizzler cone) were ~1.5lbs each, IIRC. I can check again....

    Door beams are very hard to remove without messing up the door. I would not take them out of an EVO again unless it was a flat our race car of some type and then I'd probably do a carbon fiber door instead. They are spot welded and glued in.

    The speakers, those are not on my weight list that I added.

    Thanks David.

    I read somewhere that there are plastc OEM doors, not carbon fiber. Much cheaper than the cf doors and definitely lighter than the oem...
    Do we know anyone that uses them?

    Awesome thread, i have been thinking about fabbing a tubular front cradle but i dont believe it would be cost effective, or maybe some tubular control arms even tho the stockers are aluminum. We just started selling tubular rear crash beams for cars with JDM rear bumpers that shaves i believe 13lbs off the back. If anyone is interested i can post some pics

    The front k-member that houses the steering rack isn't worth producing in tubular, we attempted it. By the time it was done the weight savings didn't justify the cost. I believe the entire front K member is only 27 pounds. Control arms, same deal, stock ones are aluminum and light.

    I've been considering working it into my next round of mods. I like the idea of nothing but an alternator to be ran by the motor. Then at WOT, you could pretty much disable everything for very short bursts...
    BMW does this on the new M3. Even the alternator voltage gets dropped.

    Toyota MR2 has an electric power steering pump...
    I think the some of the vettes do to, as well as the BMW as mentioned.

    I've just been unsure of what would be required to make it controlled. Unless the power steering pump just moves fluids and the rack controls everything mechanically...

    Great thread though. According to the list, my car is down 300 pounds from stock and still looks full interior.
