Why add bolt ons and upgrade pullies when you can do weight reduction?
Or why not do both :twisted:

Well this thread will be dedicated towards my weight reduction plan. This mr2 is going to be annorexic. thats for sure.
The plan is to build many body panals out of carbon fibre and fibreglass. I'm a helicopter structural technican and im applying everything ive learned from my trade into this mr2.
It will be expensive to do, im estimating 2000 dollars (canadian) on materials and a rediculous amount of time.

So far i have dissasembled the front section of the car. I decided on only getting the front dissasembled first and not the whole car so i can keep track of what goes where and not get confused.

What i have here is an 86 hardtop, basemodel, manual everything :D
I think that was a decent start by itself:D

The only really rusty spot, sigh.

Plan on rebuilding that cross beam out of aluminum, looks hefty

All the loot.


The lights weight ALOT! the motor and the metal brackets are rediculous, so ill have to rebuild those. I think ill have them popped up all the time and make a manual lever should i want them down, or vice versa.
The hood was pretty heavy, i was quite amazed by that. The fenders weren't very heavy though, a bit of a disappointment. However rebuilding them out of a composite material will prevent rust on them, so no worries about that one.

The bumper was heavy aswell. that will be a good rebuild.
The towing brackets were removed aswell, i really hope i dont regret that one later on.

dont suppose you could weigh things and post up the weights as you remove everything? could then use the thread as a reference point for estimating how much is lost from our own cars

Sound deadening and seats are obvious ones - Check my V6 build thread.

There's a definitive weights and measurements thread kicking about, could post that info up in there :thumbsup:

Here we go : Definitive Weights/Measurements thread (http://forums.twobrutal.com/showthread.php?t=7099&highlight=definitive)

Post your findings up in there and i'll add it to the original post.

Bit of an update.
http://www.twobrutal.co.uk/forum/images/recovered/2008/01/19.jpg

Doors are off and heavy as hell, 60lbs each
Interior is stripped, i havent checked the weight though but its alot.
and i got rid of all the sound deadening, that toook a long, long long time. ( not shown in picture). all for about 7kg

Front suspension is totally disassembled.

On jan 12th i buy myself an aircompressor(it goes on sale that day :D) to make things moving more quickly

What's your target weight for the car? Or is it just as light as you can?

interior is very heavy, ive got mine completely stripped at present and i reckon theres a minimum of 30kg in there, excluding seats. if you exchange the 2 standard seats for a single lightweight bucket seat, i think you could make a total loss on the interior of 40kg+

centre console and dash are staying. Door trim is a maybe.

Goal is under 1000kg with a v6.
which i think is easilly doable
So i think ill bring it down to 900kg

Same here.

Altho carpets are staying, I've ripped the backing off them, all soundproofinghas gone, hope to get doorcards done in carbon to house the switches. Perspex windows, apart from the windscreen.

Fully removable stereo system (I like my music so gotta have something)

Carbon bonnet, bootlid, engine lid, frontwings, t-tops, and anything else I can think of :)

bought a horrible scale today and did some measurements again, sorry that its in lbs

door 70lbs each
sub woofer 3lbs
side vent 3lbs
fender 7lbs each
lights 10 lbs each
bumper 33.5 lbs
hood 34 lbs
front cross member 3.0lbs
seat with seat rail 31lbs each
stock triangles wheels with rubber 37lbs each
towing points 2lbs for both
interior (minus dash, and seat belts) 42lbs
horns 1.5lbs
seatbelt mechanism and latches 4lbs each


oh, and they arent that accurate, id save +/- 1 lbs

awesome thats what im doing!
do you have any background experience with composite material?

Paff

I don't know a massive lot personally but am working alongside someone who does. I'm learning from him and picking up bits and pieces every day.

Everything will be tested and proofed on our own cars before released to every other bugger on the world.

Its all going well so far and will mean us peeps in the UK get better solutions to what we currently have, Obviously the TB crew will get special treatment (especially Johnny, as he needs it)
