Weight reduction

[benm]

I wouldn't go removing too much. I took out easily 40kg from my boot when I was at the drags abit over a month ago and its the only time I have got axle tramp since fitting my tyres over 6mths ago.

Removing too much weight could be more bad than good.

20-30kw more power from losing 100kg's? i really dont think it would be that much? When i have 3 passengers in the car, lets say they weigh 70-80kgs each thats an extra 210-240kg in my car.

It does feel more sluggish and the difference is noticable, but i dont think its big enough as what people are quoting. Unless your seriously into drag racing i wouldnt worry too much about weight reduction.

hicas steering rack on r33 weighs 5kg

a lock bar weighs 1kg

sorry to dig up the old thread - just better to keep all the same info in the one place

on repeated g techs one person at 70kg made my old car .3 seconds slower, the next person so three in the car now made it a .8 seconds slower....MJ i think you are under estimating how small .3 or .8 of a second is, but its alot in writing on your timeslip...

stock gtr carpet wieghs 7.3 kg replaced it with unbacked marine carpet from clarke rubber wieghs 2.1 kilos...

all the stuff in the boot i mean everything trims the lot was 26.4 kilos including wheel.

oh but if your modding your car all the weight you usually gain goes back into performance...

eg lost that wieght but added oil cooler, remote oil filter, surge tanks and two pumps, 125 mm thick intercooler, front diffuser, gauges,...

probably back to stock weight...dammit

Nah, its all good ! keep it going. I have updated it occasionally with things i have pulled out.

Its fairly complete now..

I'm trying to do the numbers & the cost to lose 100kg=*20-30kw gain doesn't add up when compared to common performance upgrades eg: Exhaust' date=' cam gears, ECU, bleed valves...etc A True Carbon bonnets must be worth around $2K+ fake fibreglass ones around $1K.

QUOTE']

those are dry carbon, my friend bought a Nismo one R34GTR for a$4000 plus. we can't say 1K one is fake as that was FRP with a layer of true carbon fibre on top. The different as not as hard, yellow color and small crack after years (heat of engine) . But weight are pretty much same.

You can get a good quality carbon bonnet made in Bris for $1300 to $1700 depending on what extra venting you get on it. Wgt for the street version between 4 and 5Kg and plenty strong enough so you don't have to worry about people leaning on it

You are adding weight when putting mods on, but then your removing to get it bcak to what it was.

So you could count that as a win situation.

More mods = more power/Better delivery at the same car weight...

As opposed to a heavier car with the same mods would probably be slower.

all too technical this stuff

What about the battery?  Lead acid batts are fairly heavy...  Perhaps a sealed odyssey style gel battery may save some kgs...

I got a sealed odyssey and that baby weighs shitloads!!

13kg or something like that

- dont bother removing the rear seats to save weight, my rear seats definately dont weigh 18kg, both parts together maybe 5kg tops

Easiest and heaviest part to take out is the space saver

Also, most aftermarket manufacturers realise that reducing weight in their components such as coil-overs, exhausts, wheels, etc is not a bad thing. Sometimes it probably intentional on their behalf, other times it just happens due to different materials, construction, etc. Often just changing a factory for aftermarket can lose a few kg here, few kg there. All adds up overtime.

So far I have tried to lighten my car as much as possible without going crazy

Quantum Coilovers - saved well over half the weight of the others that where on

16x7 Buddy Club P1 rims, extremely light compared to what I had

GTR bonnet and grill - big weight differance plus more airflow to radiator

GTR Seats, surprislingly lighter than 32 GTS ones by a fair bit

Makes a noticable differance, under brakes especially

I only ever burn 1 song to a CD when im out driving my car. The additional weight of those extra 19 songs is astonishing.  

Oh and use the blank CD's from Strathfields too. . . they are made from a thinner plastic.

bah you fool... burning a song onto a cd actually etches the information into the cd there by REDUCING its weight, if you only burnt one sone your carrying a few micro grams of unwanted plastic

[R31Nismoid]

:Owned:

lol

[Chris32]

also - the 65odd CD's that where in my car - now 4cds of MP3's

BIG weight saving there
