Ok, so I was checking out the HKS Evo the other day, the one with a bunch of letters and numbers, and I thought it was really cool. I was wondering what made it so fast and handle so well until I looked at the specs. It only weighs 2200 pounds. WHAT! How do you take a 3300 pound car and get it down to 2200 pounds. I know it has carbon fiber body panels and stuff, but I don't think that would do that much. Where would be some of the major places that weight would be. How light can you get a street Evo and how?

On a side note, is the widebody on that HKS Evo based off another kit by any chance? The front bumper looks like an aftermarket non-widebody bumper.

 

Well carbon fiber everything helps, along with gutting everything. Seats, rugs, sound deadening material, stereo, glass windows, window motors, a/c etc... Anything that is not necessary to driving the car is taken out. You can do it to your car, I am not sure if you will hit 2200 lbs, but it will be lighter. Also be real loud inside in not very enjoyable if it is your daily driver.

a/c, and abs is another big drop in weight

 

Well ac is like 30 pounds, I don't know how much abs weighs, but even with all that stuff you guys said, I can't see 1100 pounds being taken off. 1100 pounds is a LOT of weight for a car. I mean completely stripped interior, no plastic, fabric, sound deadening, light weight seat, light weight wheel, no stereo, ac, etc, would be a huge weight loss, and probably the biggest thing you could do weight reduction wise. However even with a race ready interior, it still will only remove 3-500 pounds (estimate). No where close to 1100. Do Evo body panels weigh that much that a carbon fiber body gets rid of that much weight? Not to mention the added roll-cage, chassis enhancements, fire extinguisher system, heavier engine parts, bigger wheels/tires.

 

i think the street evo wich is stripped down ,also some how good for normal driving will be around 3000 LBS . Anything less then that shouldn't be called street car anymore.

 

im also wondering what we can do to get our evo's lighter...

Things i wont remove:

A/C
Front windows
crash beams
passenger front seat

other than that, im open to all weight reduction

ill even strip the interior to nothing

what can we do to get lightweight?

 

The hks evo also wasn't a stock/street evo chassis-it was a tubalar chasis wich I believe is lighter than a normal evo chasis. Lexan windows(not street legal), carbon fiber evrything, nothing but a steering wheel, stickshift, race seat and a roll cage inside, lighter wheels, among other goodies is how they were able to drop 1100 lbs. off the car.

To drop more weight off of your car get rid of the sound deadening material, evrything that you are willing to take out of the car(spare, tools,dead bodys,etc.), get seibon carbon fiber doors/trunk, ams carbon fiber roof(this is the real deal the seibon roof is fiberglass roof with carbon fiber overlay which is actually heavier than stock roof), real carbon fiber fenders, ditch the stock seats for lighter racing seats(I believe one sparco fighter is lighter then both stock front seats-correct me if I'm wrong RobEvoRs), replace all your strut bars with titanium ones, lightweight racing wheels, and I think thats it but I might have missed something.

 

After ripping my IX GSR apart, I'm amazed they can squeeze that much weight out of the car. Pretty much everything is minimal and lightweight already, besides the obvious stuff.

 

i removed the front crash beam, the rear crash bar,wing,abs,a/c,battery,backseats,all rear carpeting and sound material,and proably more i just cant rember and i can not belief how different the car feal it's like night and day handling,with coilovers the car is so nimble,i drove my boy's evo and it felt like a tank...the *** kicks out pretty easy though...

 

Unfortunately most aftermarket CF parts available for EVO won't cut it.
Those race cars have dry carbons and/or CHC (honeycomb structured carbon)
But regardless of panels, door and windows, even if you strip down the cars to just frames, and remove useless parts (AC, ABS, airbags etc) it would be quite difficult to go below 2500lbs. The race cars usually benefit some weight reduction from aftermarket coilovers, brakes and other suspension bits, even if you get 3 way adjustable coilvers and 6pot/4pot combo for brakes. Also they probably use some custom forged magnesium wheels. Most likely they do the chassis with lighter material with more reinforcements as well.
In order for a person to get something close to HKS evo, it'll cost them well over 500k usd, but of course, if some rich dude blows 20 million and makes his own proto car im sure he can make something that is even faster while still resembling an evo.

 

they may have also stripped the car completely and had it acid dipped.. that removes every possible piece of deadening and and extra rubber or plastic all around the car.

 

no way will you get a street evo to weigh 2200, you need some major weight reduction and that will take some cutting and car will not be safe to drive on the street

 

yes you wrong. Two sparco fighter with sparco sliding rail is lighter then one factory seats with rail.

 

Thanks Buddy, I knew it was some crazy weight difference with the seats

 

Ding ding ding, that must be it. If they did indeed use a tube frame chassis, then that is where all that weight was stripped off. So basically it is just a tube frame chassis with an evo drive-train and evo body parts, that makes much more sense. I don't think 2200 would be possible without a tube-frame.
