Gtr R32 Weight

[tacker]

guys,

what a light R32 weight?

mine is down to 1280kg but wondering how much more i can get out of it

[bnr#@]

What have you done to get it down there if you dont mind me asking?

[tacker]

removed everything down to the sound proofing muck on the floor, 4w steer long gone, all unused brackets bolts heat shields.

fuel tank when today and put a fuel cell in and that alone will be the best part of 15kg i think.

[babyskyline]

start replacing everything with light weight carbon fibre

[funkymonkey]

if rules allow for it maybe remove the rad support and front and rear reinforcement bars and replace with chromolly tubing. also maybe start drilling holes in flat non structural body panels and dimple die'ing it.

[tacker]

Yes carbon fibre panels would have to be next. Is it possible to get them down to 1200kgs

[Angus Smart]

I've gotta put my fat boy on a diet soon.

four wheel steer pumps etc to go,

but i think i'm only going to end up somewhere around the 1300kg mark

[Sinful]

if you havent already stripped out behind the dash the heatercore, ac evaporator, fan etc etc all adds up.

Our car weighs 1220 and there is still a bit more that can come out if need be.

[tacker]

Yes that all long gone.

door windows winders motors etc are gone door trims too still need to take the hole saw to the door frames though.

I do have a substancial cage in the car though so there would be 30 odd kgs in that.

Looks like some gram light wheels and carbon fibre bonnet and boot are next

[bnr#@]

Go carbon doors...

[Risking]

a few other things you may or may not have taken out,

rear wiper and motor.

In mine I stripped back the entire wiring loom and removed all the excess wiring that is now not used. There was a substancial ammount of "free" weight there. You can halve the wiring under the dash easily.

ABS been removed and the assosiated wiring??

Running a full exhaust still or side pipe??

What engine bay parts have you guys removed apart from ABS?

[Risking]

There is not a great deal you can do without besides the ABS, air conditioning etc its more about saving weight.

Besides the obvious, you can strip the loom and rewire with the bare essentials. you'd be suprised how much wiring is unused once you remove the HICAS, ABS etc.

Single turbo conversions are lighter than typical twins.

Stick with alloy piping if possible.

Carbon canisters can be removed as well as the piping

Heater hoses and other water lines if you have stripped the inside out

Washer bottle and hoses.

Smaller battery

You can pretty much take anything out thats not needed if your building a circuit car.

our car still weigh's 1380!

carbon boot

carbon doors

Just out of curiosity roughly how much weight would come out of the car from only removing HICAS and its related pumps etc ?

[Roy]

If its a track car then i think you would be silly to remove ABS.

Thats only my 2c...along with the fact that everbody seems to be obsessed with removing weight, which is fair enough. But no one ever seems to consider that you can do a hell of a lot with relocating where the weight is located. ie moving it lower in the car or into the cabin/centre of the car

[giant]

i think about 10 kilo, roughly including all the lines, maybe a little more

[Risking]

you have a pretty comprehensive cage in it though.

Mine only had a rear jap half when it was last weighed. besides the carbon pannels mine is as stripped as your car.

There is always the chance of errors on the scales behalf as well I guess (public weigh bridge in my last case)

[Roy]

Dont weigh bridges only have a 60kg resolution though? The rounding error could be considerable???
