right under the rear seats (towards the front) there are these two metal plates, that are bolted on to the floor for rigidity of the car. Each plate is heavy as fuck. just taking them out will save u like 20 - 30lbs. U can probably build a custom light weigh bracing in the back.
Seats are heavy too, replace them with light weight.
Take out the a/c system if u dont need it.
u'd be better off spending the money to make the car faster, that will make off for the weight.

You're asking this question and have what? Like 5-6 subs?
If you Need to keep some bass, get rid of that crap and buy 1 quality 12" sub. The front seats are nearly 100 pounds a piece too.

Are they under the carpet? I have taken my seats out twice now and didn't see anything...
To add to this post: anything you can lighten up from the car's "un-sprung weight" like lighter brakes, wheels, lug nuts etc... will make a big difference in performance.
RP- have you ever checked out the 3G TL thread known as the "TL diet"? This guy does everything in detail to lighten up his car and ends up with more hp vs weight than if he added a supercharger. Pretty interesting stuff...

Pull the motor and tranny. Thats easily 500-600 pounds.

Next plans are to lighten up the car (if possible).
And find a really low mileage or rebuilt type s heads to mess arround with.
A little more power and a little lighter will be very noticable I'm thinking.

then yes seats are extremely heavy too, but i think the side airbags might be kinda important though, so not totally the best idea
keeping the important things, he has had blowouts before, so i think keeping those are kinda important to him

but anyways richard, there are a couple of dampening weight on the engine cradle near the firewall that you could remove to save some weight, but considering that you have dynomatted the whole car, you might not like the end result though, with increased vibration and noise being transmitted to the cabin
then there is also one on the trunk lid iirc, that could be removed also (pull the liner off), but again noise and vibrations again coming into the cabin
also pulling those spoilers would help save some weight too
also you could get a light weight battery, but you lose capactity though, which would not be good for your subs amp draw, let alone still having to be able to start your car in those

Rear seat and arm rest, liteweight battery,spare tire, jack, trunk spare tire cover, floor mats. Carry a can of fix a flat and a small air compressor instead if you like. There is approx 118 lbs according to my scale. If you never carry more than one passenger you are good to go.A cold air intake saves 8 lbs, headers save 12 lbs and a lite weight crank pulley saves 7. So thats 27 more lbs and about 30 more horsepower too. From there you can do lite weight wheels which will improve acceleration, cornering and braking.

wing is coming off really soon.
My friends going to delete the wing and paint the trunk and the hood. Just talked to him yesterday

but yeah i don't know why i keep thinking that you are a 
anyways, you might be able to get away with a light weight battery then, since it does not get nearly as cold there, but you are still going to be pushing it though, if you are going to keep those subs in, with having enough reserve capacity when those subs hit hard

depends on the weight of the car kinda, with what hp equals as far as weight
losing say 100lbs in a 1800 lb CRX, is alot more drastic then say losing 100 lbs in one of our cars, or even 200 lbs (you might have lose something like 400 lbs to equal that 100 in the CRX, idk, cause the square root thingy, i think it is called, like it takes 4 times as much power to go twice as fast)

Stock weight is 3550 lbs and 260 hp, that is a power to weight ratio of 13.65.
Now take out 150 lbs for a weight of 3400 with 260 hp gives a new lower power to weight ratio of 13.07. Dividing the old weight (3550) by the new ratio (13.07) gives the equivalent hp of 272. So, a 150 lb drop in weight is like adding 12 hp, or to answer your question a ten lb drop adds .8 hp, just less than one hp. If you can lose 150 lbs and do the I/H/P 30 hp gain, your ratio will be about 3400 divided by 290 = 11.72. That is a fun car, believe me. Quarter mile low 14's and close to 100 mph.

those braces/brackets are right in front of the rear bottoms and right under the carpet. Those are the brackets the rear bottoms snap into i think.
also the front seats are about 50 - 60lbs. rsx seats are probably around 20lb

The RSX seats still have the side air-bags in them. Im pretty sure theyre lighter, but I doubt theyre near 20lbs.

Heres the other thread:

Doing the interior plastics and the engine cover is worthless.
I have the hood for sale, but someone is interested in it right now. I also have the trunk for sale (not listed yet though).
The hood and trunk together will save you about 35lbs.
You will not be able to drop the weight of the car down to 2700lbs (S2k and RSX weight) unless youre willing to lose some creature comforts, like seats, door panels, radio, AC, sounds deadening. A new exhaust will save weight, as will a new brake setup. Headers will definately save you a couple pounds because the stock are cast iron. Remove the sunroof and put a CF inlay in there will save you around 15lbs, and thats weight up top. Remove the power window motors and pull all glass out and replace it with lexan. Id pull the stock fuel tank out and put in an aluminum 5 gallon fuel cell. Remove the bumper bars under the bumper covers, those are heavy as hell, but if you crash theres going to be frame damage. Pull out the windshield washer resevoir, the wipers and motor. Ditch the power steering. And replace the battery with a much smaller unit. Dont forget the wheels. You can find 17s as light as 15lbs.
And even that isnt garanteed to get you to 2700lbs.

the 6 speed trans is about 200 lbs less than the auto

, and the hydraulics for the clutch, but yes the entire car is still quite a bit lighter then an auto one will ever be, with the same modsand that 200 lbs is very realistic too, i would probably say 150, but either way quite a bit lighter, where one person can pick up the manual no issue, then an auto two people struggle to put it in the back of a pickup (being so heavy)

Allthou it's not a lot of weight I took off the front tow plates.
They only weigh 3lbs for the pair on the digi.
I can not feel no differance but I'm sure it will help the front suspension since the removed weight is right under the suspension more towards the front of the car.
Their not needed, why not loss the weight.
factory amp and a couple of other things will be coming out tommorrow.

but they do serve as "skid plates" kinda though, instead of hitting thin sheet metal though, mine are all scratched up
(so is the underside of my lip )and factory amp is not much weight wise, but it does add up though, if you remove enough little things
but as said before remove some of your subs would help dramatically (even if you just drop down to say two of them)

Wheels are gone and replaced allready along with alot of new parts.
I am also thinking seats would be a good way to drop weight.
Does anyone know if their are any light weight acura seats that will be I direct drop in?
Or will I have to make custom seat brackets to make any seats work?

People have given you quite a few good ideas to lighten cars. What I have done on my cars as well is take of the factory tow hooks that come on some cars. If you get stuck or need to be pulled out of a ditch, you may have a problem.
Also the other thing is replacing body parts with fiberglass or cardon fiber parts. They will reduce weight as well.

Only thing they make readily available in carbon fiber is the hood and trunk. Anything else is custom. I know some guys dropped in RSX and s2k seats into 6th gens, but probably required custom rails. I'd look into Bride or other aftermarket seats.though of I changed my interior.
Also, are you bipolar or something? You went from ghetto fab to wanting performance. Just like debadging the rear then putting a bunch of Acura insignia crap all over the front. At least your pursuing a better route.
