i heard from the shop saying that we can not have a real carbon fiber bonnet in the car, he says that if we crash, it goes in pieces, so the law doesnt allow us to do, is that ture? :confused:
thinking of getting it, but dun know where and how much usually cost.:confused:

Why dont you call up your local road authority and find out rather than rely on third hand forum information?

In regards to carbon fibre, yes it does shatter on impact = not good.

Yeah they can be very dangerous, not to mention voiding your insurance claim if you have an accident.

But apparently there are ADR approved ones you can buy, so have a look around, and contact the RTA

I'm guessing safety comes first... didn't realise it was illegal though.

it is illegal because it is not safe.

correct me if im wrong but i've also heard that there are some carbon fibre bonnets that are so strong they dont crumple, instead they go flying right through ur windscreen on impact which is another reason why it is illegal/unsafe...

It's touchy subject
If a part is properly engineered and manufactured then you will need enormous force to shatter it however its probably still not the best material for street use as its rather hard and doesn't bent like aluminium so pedestrians get owned

When it comes to race use then its great as it has much better force absorption/dissipation properties than that of say aluminum so its safer; also the reason why its used in planes...
When it does break it generally does shatter but it takes a lot more force to break it in the first place

keeping in mind some bonnets are a mix of CF and fiberglass on an oem frame. So who can really say if you're bonnets going to crumple, tare, or come off in chunky missiles.

No point discusing what things are made of and how they react. It comes down to this:

2 things....

Must be ADR approved (Australian Approved).

Must have a Mod Plate (As its a mod to the car).

^^^ Legaly that goes with anything you do to your car.

That is how it is in Qld and I would have thought nation wise.

you can just paint your bonnet black or put carbon fiber wrap on it if your really worried about the legal issues.

depends....
my aluminium bonnet is actually lighter than a full CF bonnet (not CF skin and whatever-material underneath)...
so if i wanted a "function" black bonnet look, will it be a rice crap?

I was referring to the carbon fiber sticker idea.

Is there any real reason to paint your bonnet black other than looks though?

i'm pretty sure 90% of the people out there with cf bonnets only get them for the looks..

At least it's a real CF bonnet. It's a bit wanky, if you don't actually need it. But a CF sticker is pretending to have something that you don't need in the first place! And if you follow the second law of compound wankyness, wank * wank = superwank.

ORLY!? haha.

You would only need C/F Bonnets if youre planning heavy mods on your car.
Or just have alot of money to throw around.

CF hoods = illegal. thats it.

the weight that u save from carbon fibre bonnet doesnt really make much of a difference on the street. so on the street its just for looks. on the track i guess its debatable but used with other weight saving mods it will make a difference.

Perhaps he's talking about cloths? like... Carbon fiber hoodies? I dunno if that'd be comfortable.

Shit who would have known what i was talking about, im so sorry for saying hood instead of bonnet. Who the hell doesnt spell Australia with a capital A. Idiot. Just though i might add a petty comment like yours incase you did'nt get it.

Well that's constructive deon.

But you aren't correct.

CF = Illegal. IS NOT IT.

Particular CF Bonnets are indeed legal, and can be certified so long as they conform to the ADRs.

ADRs are FEDERAL Based.

If your STATE has a law that stipulates explicitly that carbon fibre panels are not legal, then that is the law. However; most, if not all STATE laws do not imply the previous.

If you are in NSW, there is a General Guidelines to NSW Modifications Thread, whilst this can somtimes transfer to some states, you should seek WRITTEN Advice from your local traffic authority.

Fitting a CF bonnet to a car manufactured before 1st July 1995 is not illegal. 95 up models would have to meet the ADR's. "To ensure it remains compliant to the Australian Design Rules"
As the ADR's were not introduced until 1995 all bonnets made for vehicles before this time did not have to meet ADR's

Use this document as evidence if defected

download this document and look at the table on page 4.
:D :beer:

Yes irusti, your right. HOWEVER.

The document only applies to standard equipment. Carbon Fibre panels (hood, bonnet, trunk, fenders, doors, etc) are aftermarket parts and therefore must comply to ADRs.

i don't like/have a habit of typing capital letters if it's not necessary :rolleyes:

I = i
I'm = im
doesn't = doesnt
didn't = did'nt

so who is the idiot now?

to get an ADR approved bonnet (hood :p) it has the be approved for the car its going on. the rules dont just state whether it shatters or not. its more to do with where the bonnet (or pieces) end up in a collision, and the damage it would do to a pedestrian... the same rules apply for bonnets as do for bonnet scoops, if you slap a STI scoop on a silvia itd be illegal (angle of the intake), but on a WRX, its legal, because it meets the standards. you can read hundreds of pages of info on this stuff.

my two cents
