Outer Limits 4x4 Board

Well then, back onto this topic... Who'd have thought the weight of a car would come up again...

Okay - here's the g-o... Still trying to engineer my car (stupid me i know), and one of the hold ups is ADR37 (Emissions)... However, if i am able to get the zook within 112kg of the curb weight of a Cappuccino (725kgs) then I should (in theory) be able to use documentation for the Cap to say that the car meets ADR37 Requirements.

if that didn't make sense - how about this:

If i make the sierra weigh 833kg or less, i don't have to do the emissions test and i am going to save a shed load of money...

1200kgs down to 833kgs - that's a fair amount of weight to loose though i'm thinking (367 kg's in fact).

Note: Curb weight of sierra is 942kgs according to Off-Road.com...

hmmmmm, hows this

loose the tyres for a set of 26in roadies (unless you want it engineered on those tires?)
alloy wheels, as narrow as possible
1 litre of fuel in tank
minimum amount of water in radiator
pull out all the vent system behind dash
remove glovebox
take bulbs outta headlights and tailights (leave only indicators and brakes)
take low range gears outta transfer
glass outta the doors (if you still have it)
lightweight seats
empty car of all junk
give it a hell of a wash underneath and inside
get rid of sound deadening
go on a diet

dunno how much that'd get ya, but it'd be close

remove front driveshaft, take cage out, remove tailgate, smaller battery (Odyssey), get rid of ammo box switch panel thing, remove fire extinguisher, take winch off, get rci plastic seats, let Fel drive it when it gets weighed,

You are very close to what i am thinking there ant.

I don't think the car weight includes the driver, but my 1200kg reading does.

winch
doors
windscreen
roll cage
junk / tools etc
stock tyres, (stock x-fer and diffs to get gearing correct too)

can all be removed... i'll be very interested to see how it close it gets.

surely there cant be more than 30/40kg in the extra bit of roof

and id say my exo is under 40kg so thats what 8okg not much! but yes it would make a difference but i dont reckon much

I don't think there would be more than 15 kilos in the roof,
1/2 kilo in the gutters, 20kilos in the right side and 20kilos in the left, 30kilos in the rear door, throw in some head linning, some bars going across the rear windows and some rear grab handles and it is a shit load of weight

eew .. you can fit all of that in your ... oh never mind ..

some 1 prove me wrong then

redzook wrote:some 1 prove me wrong then

All I saying is, I have a rear door from a hard top here, and I have a rear tailgate from a sotf top, and the weight diferance is staggering, and we are only talking about the rear door
Peter.

Get rid of the Glass .. (at the very least) that when when it falls over .. you wont be leaving broken glass all over the place ..

redzook wrote:some 1 prove me wrong then

I did earlier in this thread

you would be surprised how much heavier they are. Extra weight in the sheetmetal, glass is quite heavy so you have 3 extra windows there. Also having the weight up higher acts like a pendulum. Once you get the weight moving it is harder to stop its swing

i wont be happy till i see the bits of hardtop on a scale

redzook wrote:i wont be happy till i see the bits of hardtop on a scale

Ok well as you have the hardtop and access to a grinder start cutting? Then carry it all into the bathroom (mind you don't hurt your back, better make a few trips). stand on the bathroom scales and note how heavy you are. Then grab first load of stuff write weight and subtract your weight from it. Repeat as neccesary until all the bits have been weighed. Then tell us

Greg if you are taking front tail shalft off you might as well tacke front diff centre axles and CVs out. Theres a couple of KGs.

bringin this back to the top
http://www.pirate4x4.com/forum/showthread.php?t=256544
according to this dude here who has just cut the back off his hardtop zuk (to turn it into a soft top) he reckons it was ver light as in 45 to 60lbs

so IF my calculations are right that is 20 to 27kg plus the 2 LITTLE windows on the side and the top half of the rear door+window

id say my 30 to 40kg is lookin pretty good

Who cares rolling over isn't the end of the world.

Chicks dig body damage remember

Just for RedZook, haven't forgotten my intention to compare bodies (with scales), just had to change plans a bit. Will be weighing Germos h'top against my softtop. just got to wait a little bit till I can get them both up the farm, hanging from a tree..........

30-40 kg thats is well above the COG is a bit different to 30-40kg sitting on the back floor though don't you agree

who cares about 30-40kg when you've got hilux axels

whats ya point 1 only said it was 30/40kg and all u said no it way heaver
nothin bout where it was located

40kg plus another 40kg for your exo (although i reckon that is a bit much) = 80kg or a average sized man sitting above your cog (this is starting to sound very weird) is going to have an effect on the vehicles stabilty. You must agree with this. If this effect that can be nullified then is worth doing, yes. Mind you I couldn't care less about it as I also have a hard top and a exo. But it will perform differently than a soft top

Wahooo!!! The latest challenge has been thrown out there............ looks like Big Steve is taking off where Greg started!!

Is C.I.T.Cold still happening?

On a slightly different note, will a s/top tail gate bolt onto a h/top body? never really bothered to look......

Imagine if you put a s/top tailgate on, early soft top doors (the ones without the regulators or glass) and removed the side glass.......admittantly you might as well have a soft top, but didn't big steve go through this at one stage on his old rig?

this was from the first page

i wasnt tryin to argue that i have a better cog then use
i was sayin the hardtop is bout 30/40kg an most of use said nahhh it is way heavier but now i have proof that if why i brought this thread back to the top.

Ok (I couldn't access the first page properly) Still 30 -80kg is heavier. I think we are arguing for the sake of it. I said a hardtop is heavier and you have also said it is heavier. i never argued about the amount but in my mind 30kg - 8okg is alot of extra weight on a car that starts at only 900kg. Almost 10% of extra weight up high.

I thought we were talking about your hardtop. I can't keep up, we need Greg back to set you straight
