do you have a weighbridge nearby? public weigh bridges shouldnt cost too much, and will give you a definate answer rather than a "should be under" answer

[Gts-t]

Yeah i will go get it done there is a few not that far away.

But first we need to speculate

Thought it might be useful for others too

cheers tho

Is your car a r32 gtst coupe?? if so i thought they were 1320kg from factory?, i have heard that the older r32's (1989-1991) were lighter as the newer r32's have extra side intrusion beems or something along those lines which adds weight to them, also factory fitted options like sunroof,abs etc will add more weight to your car.

My old 1989 r32 gtst 4door auto with sunroof and no abs weighed 1330kg on a weight bridge with full standard interior, sounds, coilovers, 17"s, front mount, front and rear strut braces, so your car could possibly already be under 1300kg with the parts that you have removed.

sound deadening stuff... pain in the A to remove, but if you want KG's, its a good place also

plus things like batteries also. is another one

[R31Nismoid]

and going as far as empty washer bottles, they hold a few ltrs so there is a few kg's there

[Gts-t]

Its a 93 coupe with sunroof and abs. I though stock weight was 1360 without the sunroof and abs, hmm.

Good to know a weight someone has actually got from a weighbridge tho, thanks

apparantly using dry ice to freeze the sound deadener then hitting it with a hammer is an easy way to remove it, i'll be testing it out soonish on my torana.

was suggested in Majanal's drift car build up thread in the drift section

Good point about the battery, ill change that when i move it to the boot.

I dont want to go overboard and empty the washer bottles, i really just want to get it under 1300kgs, with half a tank of fuel would be nice too

For now wont be removing anything else except the air con and last of the rear seatbelts.

Just wondering on what people thought of the weights i came up with and weather or not i would be under 1300.

R33 GTS25T coupes are quoted by nissan to weigh 1360kg so i highly doubt a r32 gtst will be the same weight lol, also if your driving by yourself most of the time you could remove the passengers seat as they do weigh a bit, and you could remove other things like both rear seats, parcel tray, aircon if you dont use it, glovebox, remove anything that you dont need and leave the bare essentials if you want to get serious.

[Gts-t]

Mmm interesting figure for the r33 there. Would be nice if that was correct (not saying its not)

I put the rear tray back it was only 1kg and makes it look a bit neater and the stripped back not as noticeable.

No glovebox would be to ugly for me

Do you win some sort of prize if your car's weight is under 1300kg?

[Gts-t]

No but u get the prize for being the first dickhead in this thread

im not sure what my 33 4 door weighs in at, my aim is to get it down to 1100kg, i think ill be pushing my luck but

note, its a race car

ive pulled out everything, literally, the only thing the interior will have left, is two momo seats, a set of harness's, and the dash, with nothing behind it, no air boxes, no fan unit, no plastic trims, no roof lining no nothing.

Saddly, i loose all that, but have picked up about 50-70kg of roll cage..

sound deading is easy to remove as mentioned, use dry ice, lay it about an inche thick on the area you want to remove, give it 5-10 minutes, clear the ice away, and wack it with a hammer, or just lever the side of it with a screw driver, should break up in bits, some will be harder to remove and may need more time witht he ice, but it'll eventually come away..

for anything thats left, grab a die grinder, and hit bunnings for what is effectivly a plastic scourer in a disc form, it'll get rid of what remainds quick as a flash

other stuff ive done is turf the heavy stock bonnet for a fibre glass jun copy bonnet

plexiglass side windows, 3mm thick, removed the rear door window motors, front and rear windscreens are still glass

other stuff to come is a complete reqire of the car, when i get a motec for it, so ill loose probably nearly 50kg of wire that just does not need to be there

also will be going for new fibreglass front and rear bumpers and guards..

there is a lot more i could do, but itd mean no fast glass front windows, and lots of holes carefully cut in various bits of the body, which im not so fond on the idea of..

if your really cashed up, you can get carbon fibre doors for 33 coupes, you'll pick up a good 30kg a door from those alone

and if your really keen, strip the thing to a bare shell, and dunk it in a pot of acid, to thin out the panels, the WRC cars egt this treatment, other people i know grab a belt sander and manually thin out the panels, read floor etc

[R31Nismoid]

also remove the HICAS, if you have not already

[Gts-t]

also remove the HICAS, if you have not already

Fully removed, ive listed whats done in the first few posts....

[Gts-t]

plexiglass side windows, 3mm thick

Id be thinking of this one, where did u get yours from, im thinking of having the sunroof remade from plastic too.

I just made templates of the old windows from floor lino, and texta outlined them onto some plastic sheet, then cut with a saw, bandsaw works best, jig saw will cause it to break very easily

probably a wiser idea to use lexan, as its less likely to crack and break like plexiglass/perspex will

not sure on what lexan is per square meter tho

[Roy]

Did you actually weigh the stuff you removed. Some of those numbers seem high based on the weights i have seen when ripping stuff from my car?>>>

[Gts-t]

Aah roy i was hoping u would post up

Those weights are not perfect by any means, what would u change?
