Weight Reduction
Well i didn't know what topic to put this in so i just put it in here. Have any of you guys put your Subie on a diet? I want to do a weight reduction on my 00 2.5RS and looking forward in taking out about 200 pounds. What can i do to achieve my goal? I don't want to do anything to the interior or the A/C. I know the A/C weighs alot but i want to keep it. So what can i take out that is not needed to reach my 200 pound goal?

Take off 35 lbs by going to a carbon or aluminum hood.
Take off 35 lbs by going to the light weight front bumper beam. Take off 30 lbs by going to the light weight rear bumper beam. Take off 5lbs by removing the insanely huge piece of steel in your glove compartment. Now lose 90lbs To get even more weight out, you will have to look at removing tar from the interior, or maybe getting an aluminum deck lid... -Danny |

If I'm not mistaken, you already have a stock aluminum hood. The "fake" carbon hoods that are very stiff and fit nice are actually mostly fiberglas with a layer of carbon for looks and are much heavier than what you have. An all carbon hood will be very expensive, somewhat flimsey and might be the same as what you have, maybe a little lighter. You'd want to know the weight ahead of time.

While I do agree most are just as heavy as the aluminum hoods, there is more than just that reason to swap. Also the custom full CF ones used on time attack cars are extremely light, flimsy and dont have a great top finish but at that point you arnt looking for scene points. reason I went to a CF hood (and it weighs less) is because of proper venting and a cleaner look than cutting and adding louvers. It also fits without issues. under rebuild old setup |

Finally installed the Oswald beams and they were a great mod on top of my recent list of weight reduction mods. I'm not sure of the savings, but I've become addicted to losing weight ever since I found this thread. 07 WRX So far: . Seibon CF trunk (wingless) . Seibon CF Hood (I trimmed the internal fiberglass of the hood hoping it wouldn't be heavier than the OEM one) . Oswald F+R beams . Odyssey 680 MJT in the trunk . Grimmspeed Crank pulley . APR side mirrors . Forged pitch stop mount (.5 lb lighter, nothing crazy) . V2 koyo radiator . Custom TBE with an apexi muffler . Coilovers (stance gr) not sure if they are lighter than the OEM setup. . light wheels (ssr comp c's) . Air condition, windshield wiper system, cruise control, spare wheel, front "U" subframe...DELETE Want: . 08+ plastic intake manifold, if compatible . possibly a lighter tmic, aluminum? . MAW Composite TGV's . carbon or aluminum driveshaft . lightweight flywheel . more weight off the front!!!! |

I haven't taken my AC out of my WRX, but the AC in my Miata weighs ~35 lb if that's any help.
Make sure you use lightweight (probably Subaru OEM unless you have tons of cash to burn) wheels as well as some lightweight tires. Lift up all carpet aand remove the all sound deadining padding, then reinstall carpet so as not to look.....you know... Some Miata people are obsessed with "adding lightness." There are some 1800 lb Miatas around. Later, Jeremy |

The easy part was taking out the carpet and seats and little plastic caps to hold everything in place. The hard part was squatting on the floor of my car and chiseling and scraping for horus and hours. I had a flat head screwdriver, a paint scraper and a mallet as my tools. Some sections chipped off in a million little pieces while other sections sorta peeled off. All in all, I estimated that I took out about 20 lbs of tar. Was it worth it? Eh, not really. But keep taking weight off and it'll add up after a while I guess. Other ways I've "added lightness": - removed spare and jack - ripped out trunk liner - removed metal plate from glove box door (not the bar behind the glove box, the metal plate actually inside the door, remove at your passengers risk) - took out intake silencer - removed plastic seat rail covers - took out my rear speakers (they were getting old and sounding muffled anyway) - ripped out heavy rubber pad between rear seat and the trunk - took off rear plastic strut top covers Don't bother removing the rear seat cushions (fabric covered foam) or any interior panels (thick cardboard). With all the stuff I've removed, my car is around 50 lbs. lighter. My plan for lightweight parts: - lightweight battery - aluminum hood - lighter racing seats - lightweight bumper beams |

[quote=DoinkMobb;3092345]Ah...the old sound deadening tar. That was a fun little project.

I did the same exact thing when I had a neon. was not worth it. Eventually I ended up getting my heat gun and would heat up the deadening, the get the paint scraper and scrape it up. I was getting pretty good at it towards the end after days and days and many headaches. |

Cruise was easy to remove on my 04, just pop the cable off the throttle body and unscrew the control box and take off the harness that connects it. Most aftermarket intercoolers are heavier than the stock aluminum unit.

I'm interested to know if anyone has used the plastic intake mani as well. Probably not the place to ask, but I wonder if it yeilds any gains other than weight since it should disipate heat much faster

others to add that haven't been mentioned:
lighter brakes like perrin/wilwood dynalite calipers lighter flywheel not sure what your exhaust is made out of, but if the manifold is cast iron, you can get a stainless steel one if you have a 3rd seatbelt in the middle, you can take out the assembly for it unless you want to keep it on a side note, i'm pretty surprised no one's flamed this post. usually no one takes weight reduction posts seriously |

I thought about putting my RS on a diet for a while. Found a website (the address escapes at the moment) that listed the weights of many "removable" parts of the car. It included tar, interior lining, spare tire, seats, AC, blah, blah, blah... Anyway, I added up some of the stuff and saw that I could dump about 150 lbs. But if I did it, it would be a noisy two seater and not very comfy to ride in.
