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.

loose the back seats, lighter weight rims, light weight racing seats up front, and if you go 4 or 5 point harness you can loose all the seatbelt mechinisims... loose your A/C... and your power steering... if you have power windows, or door locks you could convert those... or just go to snap out lexan windows and gut the door...


but... you sound like you want to make your car weigh less without loosing anything... hummm... I guess you could fill your tires with Helium... or COMPLETELY seal your cab... and fill that with helium too... ;-)

Spare tire, Jack, Tools, AC, steel bumpers, exhaust heat shield, gas tank shield, rear seats, all seatbelts (replace fronts with 5 point harnesses), cruise control, battery (replace with lightweight battery), Power steering system (repalce with manual rack), gas tank (replace with fuel cell), stock seats (replace with lightweight seats), Glass (replace with lexan), etc...

Good luck,

If you have ABS ditch that (trust me it's pretty heavy), glovebox, ALL sound deadner, rear wiper and motor, cut all the bracing off of underneath the hood, and peel all of the insulation from the underside of the carpet. All of that stuff adds up to around 100.00 pounds!

As mentioned, ABS is definately worth pulling. 34lbs (on a 1g) not to mention it takes up a ton of room in the engine compartment. Also, changing to lighter wheels would be smart, rotational weight reduction is always good.

damn, thats a gsx.. i have an rs.. i always thought rs's were in the 3000 plus.. so the stock gsx is just a little over 3k then i wonder how much a stock rs would be..

i did remove passenger and rear seats w rear seatbelts. i kinda felt a difference when i drove it.. my friends said it was all in my head..

im gonna try to remove the rear and front bumpers, i didnt think they were THAT heavy..

i dont think its worth it, out of all of the turbo'd 4cyl imports out there dsms are actually unique cause they have a/c, cause when most people turbo other imports like that thye usally have to take out the ac or it wont work with a motor swap

I just pulled the AC from my second 1G DSM and while it is a fairly large PITA, I do think it is well worth it. Both times I have done it, it was noticeable in the seat. I agree that it is nice to have AC and still have decent power and be able to do things the honduhs can't do, but at the same time, they arn't the only competition. On occasion another DSM wants to play too and I want every advantage over them as well. Guess it all depends on your goals.

For my 1G, it was a couple busy hours to get it all out. I am not sure how different the 2G's are. You have to make a small spacer on the 1G when you take off the compressor bracket, I am not sure if that is the case with the 2G either.

i would of thought it was just a matter of removing bolts, i imagine we had to take appart some other things to get to the entire setup.. im grr8 at taking shiet apart but i can never remember how to put it back together.. if i take it out and some day i want to put it back in im #### out of luck..

what about power steering? those extra reservoirs under the hood that make the bay look cluttered as hell..

does anyone have any ideas on how much stock rs wheels weigh? i had roush wheels last time i went to the track and i didnt think about how much heavier then my stockers they are.. thy must weigh like 30+..

Has anybody removes the SRS computer from the center console? Is there any danger in just unplugging and removing it?
