get a Cf hood,um take out any sound dampening,and subs or watnot...

>



if you dont have any money to spend on CF hood, or things like that and you really want to lighten your car, take out the back seat and all the carpet, that will help a lot.

upgrading to a CF hood is the best weight reduction mod i can think of..
then there's the spare tire and A/C next on the list

lets see, in track form i would do this to my celi for the 1/4:

"Stage 1" hahaha
Remove all trunk trim/spare/carpet
Remove back seat
Remove car audio if you have amp/sub

"Stage 2" (time permitting)
Remove a/c components and switch to small belt
Remove strut bars
Remove your crash bar
Remove your high beams while your there

The biggest change would be carbon hood and hatch but these cost money.

Another thing i did was scrap the airbag sensors and the acual passenger side airbag as it was really heavy. but if you fear for your safety (i didn't have a problem with it, to each their own) leave it in....

small car battery, remove power steering and all the bracket/hoses.
Door pannels speakers and sound system.

All that plus everything mentions above would probably reduce the weight of the celica by 200-300 pounds? Would it be worth it? not really. It makes the celica one unpleasent car to drive in.

Get yourself on a diet and only fill up the tank with 2 gallons.

It depends if you want it to be a comfortable car to drive day to day or turn it into a track car. You could consider the GT4 bonnet, it's aluminium so lighter than the steel ST bonnet but a lot cheaper than a new carbon one.
If you don't carry more than 1 passenger, lose the seats.
If you don't care about a lot of road noise, lose every single bit of carpet and trim.
Don't listen to music? Lose the speakers and player
Don't mind calling out the RAC / AA, loose the spare tyre.
Replace side windows with plastic..

It's really all about what you can do without.

Things i've done/in process of doing

a) no interior plastic trim
b) no rear seats, get ltw racing front seats (Recaro, Sparco, Bride)
c) cut out the spare tire well, replace with flat panel
d) no jack/spare
e) remove door glass/motor/rails
f) remove rear side windows, replace w/lexan
g) remove sunroof (30lbs) (replace with ltw composite plug)
h) remove heater/ac unit from under the dash
i) remove sound deadening matterial from the floor
j) custom F/G hood and VIS CF hatch to come
k) LTW battery
l) Fiberglass doors *eeps*




m) remove engine

buy a 5th gen...lol I donno how much weight reduction is gonna do in an ST. I remember at DWG Daftboy went and hit the drag strip fully loaded, came back, took out all of the stuff in his trunk, subs, jack and tools, tire, rear seats, passanger seat, and every thing that could come out easily and ran like 0.12 seconds faster or somethin along thouse lines. If i were u, unless your gonna b running your car as a pure track car, dont go crazy with it like removing your a/c. Ive been in Ottawa in the summer and it can get pretty warm up there. But if you do want a good idea of how to go with full weight reduction...check out this link.....

GT-Force

As for going with aftermarket seats for lightening. If you do, go with a single peice seat. Any of the reclinable seats come with an extra amount of weight for all of the peices that allow it to recline. I have 3 sets of seats that i can put into my celica right now..my sparco torino's, my stocks and 1 momo RSGT seat that my girl friend bought for her old celica. the lightest of them all is the RSGT single peice seat, then the second lightest seat is the stock. then the sparcos. The momo holds the best, then the sparcos then the stock, but if your gonna go for lightening, either spend the $ on a good single peice light weight seat, or stick with stock.

get rid of backseats, interior plastics,spare tire, carpet, interior plastics, interior panels, audio system, fiber hood, no body kits, small size of rims, no windows washers system,no shield over exhaust header, ac, replace seat by ligther seats,
remove the kind of asphalt in hte interior of the car for insonorisation(usualy under carpets, its called "blaxon" here in france, i dont know the translation)
and the extreme mod replace glasses by plexiglass,remove airbag system,maybe oem bumpers fiber prints <----i wouldnt recoment those 3 steps if you're on the streets

sale celi
buy elise

wow you guys are pretty freakin crazy lo, but yeah i already had taken out my subs, amp, and wiring, and my jack and spare tire and bolted up a piece of plywood to close the gap in my trunk. but yes losing ur passeneger seat and ur rear seats are a big essential to weight, the same goes with getting the gt4 bonnet hood compared to price of a CF hood and the weight of our stock hoods, and from what i'm reading you guys are goin pretty all out taking out ur dash trims and a/c and power steering (i think is a dumb idea seeing how our cars are like a tank ur gonna have fun steering) but may i suggest taking out your door panels? and taking out ur retractable mirrors and somehow switch to manual rolling windows if you have powered windows.
Also, i dont know how your laws are over where you are but where I am, in Windsor, Ontario--I believe it's legal to drive without a hood. hehehe i just re-did my friend's car from ground up, and he sold his hood, so as of right now he's got no hood = better air induction for the intake and won't have to worry about heating up also that's a good 30lbs probably lost
p.s. take off your mudguards if you have them on.

you do know that that 30lbs you lost in hood weight you gained in screwing up the aerodynamics of the car and creating a TON of drag

lexan glass all around

I know this is going slightly off at a tangent, but if you lighten (by buying / making new ones from aluminium alloy, not drilling holes in your existing ones.) your drive pulley, power steering pulley and alternator pully you are saving an engine load in a slightly differnt way. Also, once you remove your stereo, electric windows and other items, you won't need so much power, so you can get an oversized alternator pully, further reducing engine load.
I wouldn't recommend taking out power steering unless you only want drag strip performance, if you want to do some real racing / track days you'll most likely go faster with the power steering. You could oversize the pully to make it a ligher load on the engine but slightly heaver on your hands.
If you're good with such things you could try lightening your cambelt pulleys (Make new ones from lighter material), but that's beyond me personally.

the celi is not that hard to drive without power steering, my opinion. Does it really make that much of a difference by taking out all the carpet and interior pieces? i agree with the back seats coming off because thers really not much leg room for the people in the back. I dont know i ask because i want to keep all my interior and still go to the track and have a beast. but like everyone says if its strictly race then take everything you can

The st is pretty light, only a couple hundred more than a 88 corolla gts.
I have plenty of silly answers but I DON"T THINK THATS HELPING.
Look for stuff you can live without.

leightweight rims help a lot with moving mass...leightweight pullys and flyweel(if its stick) i know this sounds redicilous but leightweight lug nuts....plexyglass the car...no spairs...all plastics under the car to help with rocks and scratching the underbody....inner wheel well plastics.....that insulation under the hood if it has it? mine doesnt.....headliner....wing...no bodykit....and a hammock you can lounge in

get those 14lb carbon rims, cf hatch and replace glass with lexan. get rid of backseats, carpets. get lightweight seats. put only a couple gallons of gas in instead of a full tank.

race with a quarter tank.
remove the spare tire
remove the back seats and carpet
remove the passenger seat
and you will be running around 2400 lbs in your 95 gt!!

Thread cleaned*

Lets try to actually help this member with some real tips. Personal attacks are not acceptable here.

do what nascar cars do. Fiberglass stuff.

Fiberglass fenders, carbon hood. all uncesseary interior trim off, hatchback glass/door, get one with cf and plexiglass.

remove all seats...

not much improvement but, could help...

Does everyone realize this thread is from January?

so whats your point?

You forgot to add the part about letting rust eat holes out of your exterior n then just throwing vinyl graphics over it so you don't see the holes lol...... but really, yeah, there's tons of stuff you can do and playr158 definitely has the most constructive/organized list.... it all depends on how far you're willing to go n how much street driving you're trying to limit yourself from being able to legally do

Do we have the sound deadening tar under the carpet? We should right?probably 35lb's

yes we do have that stuff, i don't think its quite that heavy though.

>

What size are those 14lb Carbon rims?

RS Limited (same company as American Racing) has a 15" wheel called Concept Pro that is supposedly 13lbs per wheel(prob costs $1000s less too).

FYI, the Seibon OEM style CF hood is only 12lbs lighter than the stock sto hood, hardly worth $300-$500 in my opinion.

We need to band together and find a manfacturer that will make plastic replicas of our gas tanks that can be mounted in the same spot for convenience. Anybody know how much the gas tank weighs? Estimate or guess on how much a plastic replica might weigh?

After finally doing some research, it doesn't sound like plastic tanks would be a good idea (mounted underneath anyways). Read that they will melt and dump the gas in a fire
