The Weight Reduction Thread!

[NEEDforSPEED]

As many of you realize are cars are quite a bit heavy, so in my quest for lighter 3rdgen, I decided to just play around with a few parts and a scale probably not the most accurate one, but good enough to get a rough estaminet "give or take 0.5 lbs." I'll begin with the most basic stuff. as my cars pretty much all disassembled im going to ditch some weight by trading the heavier parts for lighter ones, I hope this will help out some other 3rdgeners in the quest to ditch the extra non-needed pounds, Feel absolutely free to add to the list! Heres some of the stuff i did, 1. "083 casting 5.7 tpi head" 2. "iron exhaust manifolds" 3. "iroc hood" 4. "hatch no spoiler" 5. "aluminum drive shaft" 6. "radiator"

[NEEDforSPEED]

Heres the hole iroc front clip!

[onebinky]

We've got about 3 cars in our basement, if I get bored tomorrow I can weigh a bunch of stuff and add to the thread

[nape]

Front bumper support = 37lbs
Air bag sensors combined (3 pcs) = 2lbs
Nose = 16lbs
36mm sway bar with brackets/bushings = 15lbs
AC compressor = 15lbs
AIR pump = 7lbs
AIR diverter valve + lines = 4lbs
Stock LCAs = 10lbs/pair
Pro-fab tubular poly/poly LCAs = 8lbs/pair
Stock torque arm = 10lbs
BMR Adj torque arm = 16lbs
Formula wheel with bald 225/50/16 tire = 40lbs
Formula wheel with 245/50/16 tire = 50lbs

[Spdfrk1990]

Anyone know the weight of the stock seats they seem pretty light.

[NEEDforSPEED]

if someone dosnt beat me too it, i have leather - leather power - and regler camaro ones - i'll hit them all.... 4thgens are much lighter then are 3rdgens by more then half! just a fyi

PS. im not pulling thos out to see how much they are
lol

[mw66nova]

fourth gen seats + third gen sliders = instant lightweight seats! i didn't weight mine, but by carrying them around, i have to say that they dropped about 8-10lbs. a piece. and look NICE too!

[Spdfrk1990]

Thats a good idea if I was that big into weight reduction.

[Pablo]

1 peice rear seat with seat bottoms 27 lbs

the seatbelts for those seats are easily more than 3 lbs though i didnt weigh them

GTA crosslace wheels are 45 lbs less all together than the 16" "turbo fin" wheels

[mw66nova]

*update* went to the track today and weighed the car, official results:

3045lbs.

[Spdfrk1990]

Thats light

What all have you done for weight reduction? Is that with you in it?

[83 Crossfire TA]

How much do you weigh and is that included in that weight?

[AutoX86Z28]

i havent weighed my sportcoupe yet but i think its close to mw66nova's, no power windows, no power locks, no power hatch, no ac, no smog.

o yea and the GFX are about 100 pounds IIRC

[NEEDforSPEED]

Fyl wheel 4.5lbs
rear bumper 11lbs
fender 12lbs
t-top 16.5lbs -- i got 32.5lbs as a set
t-top bag 4.5lbs
iroc tail lights 7lbs

[Spdfrk1990]

Whats the fyl wheel thats 4.5 lbs???
Only thing i can think of is fly wheel and its no where near 4.5 lbs.

[NEEDforSPEED]

what do you mean?
i put both the fly wheel and drive shaft on the scale and i got 20.5lbs and i weigh them sperate too, drive shaft 16.5 flywheel 4.5

[Spdfrk1990]

there is a fly wheel about 16lbs and one that is 25 lbs. You must be talking about a auto and there usually not called fly wheels.

[onebinky]

auto=flexplate
manual=flywheel

[305q_ta86]

That must be what he meant..

[NEEDforSPEED]

ya i did, :slaps head:

[mw66nova]

3045 is without me. it's 3300 with driver in race trim.

no front sway bar
manual door/locks/windows
only accesories are wp/alt/ps
fiberglass hood
fourth gen seats with thirdgen sliders
no sound deadening material
headers/dual exhaust which i know weighs less than stock
aftermarket front carpet
no subs, but stereo is in tact
no back seat
can't think of anything else

fatties and skinnies would put me under 3000 w/o driver.

[onebinky]

Interesting.

I have P/S delete, A/C delete, smog delete, AIR delete, headers, 3" hooker exhaust without cat, stereo delete, fiberglass hood, T5 trans swap, no sound deadening, rear seat delete, front sway bar delete, and a pruned engine and dash harness. I wonder if I'd be under 3000 pounds yet? I do have power hatch, windows, locks, and GFX still though. Power hatch will be coming off soon in favor of the old slam and close Oh yeah, I also have paint deleted...

EDIT: Does anyone know if rt66 raceway has a scale? Do they charge to use it?

[83 Crossfire TA]

Seems like some camaros come in really light. I’ve had my ’83 TA and my ’87 Formula stripped down pretty far and I’m nowhere near that. My formula, with basically everything in excess removed under the hood, simplest exhaust everything that could be easily removed, removed, basic stereo (head and 4 speakers), light wheels/tires… still weighs in at 3710 with me (I’m probably about 300#) which is still nowhere near what some of you camaro guys are reporting. I know that the flip up headlights are worth an extra 30-40lbs and looking at your list I see maybe a little over 50# difference, but that still leaves 200some lbs unaccounted for.

[NEEDforSPEED]

the front clip is now 36lbs ... i should probly fab a bar just for more safty if i every where to smash the front of the camaro up

[NEEDforSPEED]

btw, i took off 28lbs to the clip

[vejatabul]

i just found a car in the junkyard with a/c delete and radio delete. i grabed the heater box and controls, and the interior panels that have no sail panels and no speaker holes. i think it was a match made in heaven for me, since i was just looking for a black interior plastics set. i always wondered what i would put over the speaker holes.

[megaracerx]

i vote to make this a sticky!

[Spdfrk1990]

vejatabul lucky find im lookin for somethin just like that but i might just get a custom radio pod made.

Do you have a pic of the sail panels? I don't think I've ever seen those before.

[mw66nova]

anyone got a lighter car than me? looks like right now i have the lightest street driven thirdgen on the boards, i don't know of anyone with a lighter one that is their everyday driver.

[Digital GTA]

My '83 is at 3170 with everything on there.

Tony you Dork

[onebinky]

I do, but I don't have an engine in it at the moment

This spring I will hopefully be weighing it.

[EvilCartman]

Just changed out my water pump tonight to an aluminum one.

Stock replacement water pump: 14.5 lbs
Edelbrock's Victor series aluminum water pump: 8 lbs

I bet mine is lighter

I have to get it weighed though. I wouldnt be surprised if i came in under 3000.


Well now that I think about it, I did add a 9 inch to it and that is a heavy SOB so maybe not... we'll see... but i have more stuff removed than you do, lighter wheels, and a t5 which is 100lbs lighter than the 700r4

[mw66nova]

eventually, i will be doing more weight reduction, to include lighter wheels (fatties/skinnies) and an aluminum ds. i would like to put some more aluminum stuff like waterpump, etc. but funds aren't saying i can do it just yet. i am putting in a 10" torque converter, and that thing weighs alot less than the stock 13incher.

what else do you have removed?

[Pablo]

I removed the front crash beam and everything under the nose, no fog lights, no washer reservior or motor, aluminum water pump, removed the entire left bracket and tensioner for the serpentine setup, just running the right side with my own fabbed up tensioner slider doohicky. No spare, no jack, no carpeting, no evap canister no emissions equipment of any kind, no ac, no ac/heater fan or box or panel of any kind. Corbeau race seat for the driver, no hood insulation. No swaybars front or back.

Probably a bunch of other things here and there. When you open my hood all you see is an engine and basically nothing else.

Before i converted it to a T5 and did basically everything to it i weighed it at 3270 or so.

Doing the AC and crash beam was probably close to 100 lbs alone

[AutoX86Z28]

is anybody running a S-10 manual steering box on here? ive been looking in to them lately, excellant way to shave some weight .

[GTA4ME]

You should trade out your stock hatch for a Notchback! It's a lot lighter and looks sweeeeeeeeeet!

[NEEDforSPEED]

convics me...
thorw up some pics man

[mw66nova]

personally, i think that the notchbacks look hidious

my car was originally a v6 car, so when i swapped, i pulled most everything out. i am running a serp/v-belt combo from an 87 v8 car, hope to get underdrive pulleys for it soon too. but it has no emissions stuff, etc, etc. i do however, have the non ac heater box with blower motor in and operational.

[nape]

Originally posted by Pablo

It's actually probably closer to 70lbs.

[Pablo]

i included the bracketry (the serpentine bracket and tensioner) and ac box and motor, the ac head unit etc

Maybe not quite 100 but more than what people generally quote for weight drop when they remove their ac.

Alright, you were probably close to 100lbs then.

Passanger side bracket bare should weigh 10-12 lbs and an AC delete heater box with no motor weighs ~3 lbs.

I'll get weights on the stock AC coffin when I finish my swap.

[NEEDforSPEED]

it should be 70.7, witch should be right on the money at lest thats what mine came out too, look above in the thread i took off 28lbs off the front clip so 28 -
Air conditioning 41.7 with V-6
Air Conditioning 42.6 with 305 TPI & 700R4
Air conditioning 46.3 with 305 TBI & 700R4
Air Conditioning 42.7 with L98

Here's one.
