talked to a bloke out at spoilerfactoy today ,

and he was telling me that any skyline that was produced before 1995 was alright to have a carbon fiber bonnet the only issue was the holes ponting to the windscreen ,if they are closed it is legal

is this bullshit or what ?

cause i would love to get a carb bonnet, but not if the cops are gonna pull me over and see all the other shit under the hood

#######sorry about the double post, accidently pressed the post button then tried to change and ended up with 2 post.

reason to put carbon fibre bonnet beside reduced weight is to put to asssist cooling with the vents. something that factory bonnet is lacking. no point getting a carbon fibre bonnet if u have to seal the holes again. with such lightweight bonnet u need to make sure its secured properly and wont pop up on the freeway because it's "floating" against the wind pressure inside ur engine bay. having vent will reduce that lift effect. u can have have secondary bonnet restraint like in race cars, but u can get hassled having it on your road car as they can argue its a sharp pointing object that may cause injury if say... u hit a pedestrian (touch wood) and he/she slides over the bonnet and got cuts from ur vents or bonnet pins. laying low is the best defense. i'd rather have a wolf in sheep's clothing but its up to you mate. everyone is different.

I posted this in your out thread.

Please try and not doubble post topics.

In my opinion, According to the Eastern States Laws.

This is Pure and Utter Bullshit.

However, In your state Carbon Fibre bonnets, Maybe legal.

However the Bottom line is..

All bonnets must meet ADR standards, This means All bonnets must Crumple on Impact.

A carbon Fibre bonnet does not, It splits and Shatters.

Therefore Rending the Bonnet Not Legal.

The Smarter thing to do will be to contact the correct authorities, to check if mine or 'This Spolier Guy's" comments are correct.

Thanks,

Essential.  

     

I have a question though, bonnet pins may harm a pedestrian... then is it legal to have those...i dunno...scoop like things you see on old fords and holdens...dont know the technical term, but they stick up right out of the middle of the bonnet... if small pins are illegal then how do they justify those things? (hope someone knows what im talking about :P)

It sucks, these car manufacturers can pump out pieces of ****ing shit because they suck off the government ministers, while we make SAFER mods and get raped for it????? Anyway, pssst, go get yourself some 'carbon fibre' contact, get a AIIIIIGHT shop to put it on for you, looks like carbon fibre but the weight of a normal bonnet, and VERY VERY CHEAP if you just want the look and no hassle from piggas (piggas are niggas who never could handle da hood)

its to do with the age of the vehicle.

I had an old 79 ZJ with a big scoop... but it cant be touched as it relates to a different set of ADR's :)

same as older cars dont need to run Cat converters...

older cars are allowed a higher DB limit on thier exhaust.

All sorts of things like that. You cant expect a 30 year old car to match currecnt ADR's

As for bonnet, it wont be legal in any state, as ADR's... are Aust wide.

Before they started having to crash test vehicles, you could do almost anything you liked, within reason.....

These days to comply with ADRs the manufacturer needs to do front impact testing to prove that the design of the bonnet and hinges will not cause the bonnet to come through the windscreen and cut your head off.

If you change the design, or fit non factory parts to your bonnet, catch, or hinges, the modifications would almost certainly be seen as illegal.

Yeah, there is a scoop.

Thats what has me totaly dumbfounded.

"apparently" its allowed to be a hold of a certain size... if you drill down into the law a bit more. Not 100% sure how Subie still got away with it though as the STi scoop is quite sizeable

I tried to get an answer to this very question from the RTA (in NSW) and was referred on to some engineers, who all disagreed with each other :)

The answer seems to be that nobody has a clue.

A few answers I got:

Hi,

This depends on the year and model of the vehicle as to whether it has been

subjected to ADR69 being full frontal impact protection and in particular if

an airbag is fitted.  Without testing (that can be very costly), one can not

continue to claim compliance with this rule once the material of the vehicle

strcuture has changed.

Regards,

Morry.

And (read from bottom)...

The material in itself is structurally sound but the application of it has

to be structurally sound.

Hi,

Thank you kindly for the prompt response.

The material is structurally sound, however it has been suggested to me that

because carbon fibre has a tendency to shatter rather than bend, that this

could

be a problem in respect to the ADRs?

Thanks again for you time.

Lucien.

    • Hello!  i just finished manual swaping my r34 skyline with a r33 rb20de box(RB71C)box  When the car is running it squeaks crazy loud and it was smoking from the gearbox area. The gearbox is fine it was tested. The clutch slave cylinder seems like it doesn't fully releases the clutch. I want to ask if this noise is from the throw out bearing or could it be the clutch assembly or disk att.xFliq87Gzw6kImKBVqDebXkj0fBqymk0JaYeP3_3SlM.mp4
    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always!
