DSM Weight Reduction [merged] diet weight loss strip light

[98TsiAWD]

I personally am looking to do some weight reduction while retaining the quiet/smooth ride, and still having a spare so I can go on the highway without getting flatbedded home.

heres some of my ideas, just normal of course.

CF hood
Ditch all of my stereo and just get upgraded 6x9, 5.25, and 3.5's hooked to the factory amp/deck.
CF Hatch<<<Anyone make one for us?
CF Spoiler<<Anyone make it?
Dimple Drilled/Slotted Rotors


What else is there? I dont wanna tear out all the sound deadening or the spare tire.

Remove all the sound deadening tar.

Dry Ice + Chisel.

Get lighter weight wheels.

Polk Performance sells suspension parts for the 1g. You should hit them up. Great guys to work with. Shep runs a few of their parts. Polk Performance

I'm in the process of buying a turbo'd 97 Eclipse . What I want to do is reduce the cars overall weight, are there any companies that make weight reduction kits for the 2g Eclipse?If so how much do they typically cost? I know there are ways to do it, but I want to do it right so I won't have problems in the long run with the car.

I've never heard of that sorta kit for any car.... I mean... if ya wanna take out weight, your car is gonna have to end up looking a little meh!!.... take out whatever you dont use.. carpets, seats, AC, spare tire, etc.... but I rather be a little slower than having a car that looks like shyt with no inner body panels.

You can do two things at once tho here, start buying light weight engine parts, which will save you a lot of weight and give you better performance, such as radiator, oil pan, exhaust, etc..... all these will be made outa light wieght matieral, and give you improved power.

 

[Defiant]

Uh... yeah. Lightweight engine, that's the ticket.

Meanwhile, somewhat more adjacent Earth, you could go for a carbon fiber hood, fiberglass fenders and bumpers, and if you're nuts, lightweight glass replacements and a carbon fiber hatch. Which will all add up to about half-again the cost of the car, and save you about 400 pounds.

If you want a light car, a DSM isn't really the best platform to start with.

weight reduction kit? what is this gran turismo?

unlike video games its rather inexpensive to remove weight from one's car. it all depends on how much you are willing to give up, and if you have 10/12/14mm sockets.

Stock radiator ways 6 lbs. You can't beat that. see link below. And also from experience the fluidyne is way heaier than stock. You can get lighter more effecient fans though, spal, slimline, etc....

I'm not new to cars what so ever but this is only my second DSM and the other cars (non-DSM) I owned had weight reduction kits, though they were extremely hard to find.

 

[cait sith]

Ok, Mr. JDM.

Weight reduction kits.

 

[DSM_JDM4Life]

ok so they're not actually called "weight reduction" kits I call them that so it's easier for me to remember. I was thinking since last time I posted that I could replace the stock pieces with CF or FG instead of the heavier sheet metal and other materials. Anyone think that won't work for a Turbo'd 97 Eclipse?

I would think that the FG fenders would actually be heavier than the steel fenders due to the multiple coats necessary to build up the same strength. Personally I prefer to keep my steel fenders as I'd rather have the steel fender in case of an accident, and have it bend with the forces rather than an FG rip, crack, or shatter.
The other thing would be fitment, paint and bodyshop time. Plus do you want z3 or m3 or whatever vents... Personally I prefer to keep my steel fenders as I'd rather have the steel fender in case of an accident.

I have seen that the CF hoods weigh several pounds less that the steel ones, but I would drop the weight off the rims or driveline first if you are interested in acceleration more so than just max g on the skidpad. (constant speed) If going for a roadcourse or Autox type of car check the rule book to make sure that the mods you are considering will not push you to a different or high class.

You can easily lose 20-30 pounds by going to a lighter wieght wheel, and because of rotational inertial it will actaully accelerate as if you had dropped a lot more sprung weight.

97 GSX wheels are listed as weighing 25LBs. You can get 17- 19 pound wheels not too expensively.

Dropping 10 lbs from the driveshaft on an AWD is pretty much the same thing as from the wheels, but I see you have a FWD.

Dropping weight from the flywheel will also improve accelaration and braking

Definetly agree bon fenders, i Think the steels weigh 7-8 lbs each and the fiberglass weigh 3-4 lbs each. But i am definetly in dropping the weight the weight on the awd dtrivetrrain, what can be done ??

 

[16g-95gsx]

Yea, CF hood and lightweight battery relocated to the trunk are some very nice alternatives on DSMs. Wheels are the first concern however IMO just as people mentioned. The overall look change to the car as well as the performance gain is well worth it. That prostreet weight listing is awesome. We really should have a ton more submissions to that thing, I'd love to find out the various weights of everything, such as aftermarket parts as well as OEM parts such as 2g leather sets. I know my drivers seat is a pig, and I'm also curious how much weight I dropped from my exhaust work. I weighed my car in at 3100 even without me in it and around 3gallons of gas, just for an idea.

Well for one thing you can go with an aluminum driveshft from the driveshaft shop.
Its a bit expensive 750 or so but according to the article on Modified, not only is it lighter by about 10 12 lbs but it is smoother and has less friction as you go from a 3 piece to a 2 piece, thus reducing power loss from the exra carrier bearing and extra u joint.

 

[DSM_JDM4Life]

oh what to do what to do . So much to take in with a cold :thumbdown Oh well dunno if I'm gonna switch fenders yet. After I get everything else all done and taken care of I'll give the car many a look ever to see if differant fenders would match or flow with the overall design of the car.

 

[Mooney]

Have you guys ever thought about spot welding the car to loose weight. I did it on my ae86 and saved around 500 pounds. bassically its were you take out all the useless sheet metal from your car. You cant do it with out a roll cage and probolly dont want to drive it on the street but it works if your looking to make a fully race car.

like I said before what to do what to do I don't want to cut or harm the frame or body, just alter it so the cars even slightly lighter

hello. i drive a BMW e36 M3 as a track car. as with any track car, even weight distribution and low weight is key. I'de like to, as research, convert my 1992 (POS daily driver) eclipse into a car with lower overall weight and better chassis balance. does anyone here know anything about the weights of unnecessary parts? i am willing to take anything out that doesn't affect the mechanical integrity of the car, so i am looking for any known weights of useless components or any suggestions as to what could be taken out. that means air conditioning, carpeting, seats, wiper fluid reservoirs, ANYTHING that will reduce the weight of the car but maintain its street legality and ability to drive. the second part, weight distribution, is the other question i have. are there any vehicle components that could be shifted to the back (or closer to the back) of the car in order to balance the weight over all four wheels? if so, any ideas as to how much these weight? i am a BMW fanatic and have done well to reduce the weight of my M3, but i know very little about the eclipse. i am running skidpad roadholding and accleration/braking trials to get numbers and overall improvments as a function of weight removed and weight distribution change. strangely enough, i am an aerospace engineering student at cal poly san luis obispo and this would be a great supplement to my conrols and dynamics class, in addition to improving the driving characteristics of my poor eclipse
thanks for any help you can provide!!

Here is a link to reference component weights:
http://www.prostreetonline.com/pso/pages/techtips/dsmweights.asp

As for as the reduction side, it sounds like you have experience on your BMW, you should be able to use the same knowledge on the Eclipse.

 

[bmw m3 redwing]

Wow that site is cool. I wish there was an M3 site like that before i started work on that
I know enough about weight reduc to do the job, but since i am looking for really specific relations between performance and how MUCH and WHERE i take weight out, i needed a site like that, so thanks
now i need to find out how i can get more weight to the back of the car so that damn thing doesn't understeer like a bastard!
any ideas about moving heavy components rearwards? engine? tranny? anything?
thanks again,

-Robert

rip out all of the sound deadening material, you will have to basically stip the whole car down to do this though.Then once that is done you can do the typical remove rear seats, passenger seat, A/C, all stero equipment, floor mats, replace battery with an aftermarket lightweight one(braille), and only fill the gas tank up half way.
It won't be a fun daily driver, but it will help a lot at the track, on a 1g GSX you'll gain 1HP for every 15.9 pounds shaved off of the car.

 

[Twizzle]

im sorry, i know this is critical weight savings or w/e but... ripping out your carpet just seems a bit silly... having bare metal just to shave off 2 pounds is ludacris.
