^^^ Thats not doing it right

the awkward moment when doing it right the first time is not possible for the average hachiroku owner




so the rule is simple: go full carbon, the hard part is going full carbon..so simple yet so hard

on another note

my coupe i bought was claimed to be at 970kg? without driver
it had fiber glass vented bonnet and pair of front guards, no rear seats, 50% sound dening removed, not sure if it was 100% as not bothered to check under the front half of the carpet, no air con as per standard...had power steering setup and 90% of plastic interior, bucket seat for driver and normal for passenger..

for a car claiming to be 970kg, it sure did felt lighter then when i drove a hatchback with very similar weight deduction without power steering on the hatchback too..maybe its just a coupe thing =p

P.S Notch backs are more rigid then hatchbacks, can speak from experience now
just sayin.

I am very unsure about the carbon roof thing, I just don't think there's lots of weight in it and it's a strong structual component of the car

[Delazy]

Strangely I agree, but a lot of evo's run carbon roofs and drop reasonable weight..

If I was to ever do it, it'd purely we wank factor..

[Sam-Q]

well I guess it is the single best place to loose the weight.

Also anyone who has an electric sun-roof should take note- they are 20kg!!

i would only go carbon roof if i had a reputable cage and it had gussets on the a and b pillars

This is what I would do:

Remove all trim
Remove door cards
Top of dash only
Remove heater or air con stuff
Remove sound deadener
Remove glass and replace with lexan
Remove bonnet and replace with fibreglass/carbon fibre
Remove fuel tank and replace wheel well, add small fuel cell
Remove radiator wall and replace with simpler, lighter design

Here was my solution:



Square and angle alloy. I found that only the two bolts on the inside of the headlight enclosures were needed to support the headlights and grill.
