It is now being mandated in racing to put kevlar over the top of composite parts to stop them shattering as well.

And on the weight issue, most fabricators don't really know what they are doing when it comes to carbon and treat it like fibreglass so you end up with a product heavier than the aluminium parts anyway.

Given the recent threads it would seem the legality of the carbon bonnet seems to remain in a grey area, or at least whether or not you will be booked for it.

the two rules that apply are

ADR 12 Glare reduction in field of view.

ADR 69 Full frontal Impact occupant Protection

DOTARS told me that for the 32's ADR69 does not apply but not 100% on the 33's, they did not mention them.

The other usual rules apply with hinging and latching and scoops.

So that means that on a 32, a fibreglass bonnet, carbon fibre or aluminium bonnet is completely legal as long as there is no excessive glare and hinges and is latched correctly.

I do not see why this would be different for an R33. I would seriously contest any fines that have been issued as this has come from Department of Transport themselves.

May we have copies of this? I am a 32 owner in want of a carbon bonnet after my little hail dance incident. Let's see hail dint that ferker.

Yes, you may all have copies of this....just pay the $70 for a copy of the ADR and it's all there.

Other than that, there is a member who has a copy but I cannot remember who he was. He posted it in a reply to someone once so you might be able to do a search and ask him about it.

yeah, i would suggest that people with GTST's get the CF bonnet resprayed a normal colour so that its not as obvious to the cops?? I would just save so much hassle with the cops!!

Anyone with a GTR & a CF bonnet must really want to save every gram!! as said above the aluminium bonnets are prob .5kg heavier........other than that it sucks because the CF Bonnets look hawt!!!!

this of course excludes squizz, sorry to hear about the hail damage after the storm!!

i would love a copy of the ADRS ^^

I talked about this with Ben at Hardcore Racing today, he is a mechanical engineer and he said that mods should only be defected by accredited persons as he can certify something but any wally with a badge can defect it and then its up to you to defend it, to this end he has a deposition to the police asking to clarify this and he is in a postion to change this FU system by lobbying. As to my bonnet he told me the ADRs for that year of production (1996) apply to my car and what will pass for mine could be different for a 1997 car and so on, and as the years go on the tougher the rules, so a 1988 car will have less restrictions than a 1998 car etc.

If I find out more I will keep you posted.

Also, for bonnets, whats the point? (apart from if you have a cooling problem) as an Aluminium GTR bonnet is probably only .5 to 1kg heavier than most 'carbon' bonnets out there

there is no real point to it on a gtr as probly more then 90% of the so called "carbon fibre" bonnets in australia are fibreglass bonnets with a carbon fibre skin on them making them heavier then the aluminium and illegal,

makes it in the same category pretty much as putting diff bov's on the gtr even though the stock ones are good for more power/boost then most gtr's in qld are making and also have the advantage of being legal. :confused:

I have a wet c/f bonnet (fibreglass/cf overlay) on my z33, it came with an aluminium bonnet too but the c/f is lighter....but i just wanted it for the looks, i haven't checked to see if it's legal but my insurance company has just knocked me back for haveing it, i have a insurance broker seeing who he can find for me.

    • My take on gg2 48mm, 54mm, 58mm, and 62mm compressor map for same size compressor vs gg1 : All gg2 only outflow gg1 above 20 psi. As all g gen 2 surge line at lower left of comp map move to the right, all gg2 sacrifice spool vs same size gg1, surge line move to the right worst for 54mm gg2. So for same size compressor if you want best response, use gg1, if you want max hp at >20psi use gg2 but you will be laggier vs same size gg1. Max compressor efficiency drops to max 75% on all gg2 vs max 76%-80% of same size gg1. Iirc lower efficiency means hotter iat less dense air so lower hp at same operating point of comp map. Also curious why gg2 is mapped to lower max rpm vs same size gg1 (only 48mm size both gg1 gg2 mapped to same rpm) : 54mm gg1 165,000 rpm  vs  gg2 160,000 rpm. 58mm gg1 150,000 rpm vs gg2 140,000rpm. 62mm gg1 145,000 rpm vs gg2 140,000 rpm. If gg2 can safely spin to gg1 rpm then they can flow a bit more than as mapped. Good thing that all gg 2 interchange compressor and turbine housings with same size gg 1. So gg1 owners can buy gg2 chra only if planning to boost >20psi.
    • My stuff is all with Shannon's, granted, I don't really have imports I'm driving on the road, however, I've had multiple cars at the same time with them. Presently we have the Landcruiser on laid up cover, Sarah's Kluger on full cover, and the house insured. About 18 months ago Sarah wrote her Subaru Liberty GTB off, insured with Shannon's, and the payout, and buy back of the wreck was super quick. In 2020 we had the VF Commodore totalled in a major hailstorm. Storm was on the Saturday, I called on the Sunday and lodged it, vehicle was towed on Tuesday night, assessment team called on Wednesday to say it was a total loss and get payout details, money was in the bank on Thursday morning. Have had a few other claims both at fault, and not at fault, over the years, and never had an issue with them.   Funnily enough, they're also the cheapest insurer I find for things like Sarah's Kluger.   I will say I'm less impressed dealing with them lately around "the experience", as a lot of their staff that you deal with aren't car enthusiasts. Shannon's has a much more main stream feel ever since they decided to become "big corporate", laid a heap of staff off, and then hired a bunch of non enthusiasts. At the same time they've been making a push to be less "call us and we'll personally have someone who cares help" to "hey, this computer can do stuff for you" and are trying to get more square pegs to fit round holes. (That's just the vibe I get from them). Again, have had no issues with claims with them, but get a bit of a "less personal" feel from them.
    • A thing I wasn’t happy with with enthusiast was during the initial phone call they told me they’d insure it for 130k but needed photos.   I then sent them photos and they told me $80k as there were other cars either similar modifications available for around that price, I told them to send me the links to said cars so that I can buy them. i then sent the modification list with prices of the parts (no labor) and the price then came to 115k, which is still shy of the 130 that was agreed in the initial phone call 
    • Ask me a bit later this week before payday
    • I agree that delayed payment probably isn't the most suitable solution. It seems a solid complete transaction would be best. As I wouldn't be using this sale as a line of credit that would typically earn interest, we can probably arrange a much cleaner single transaction deal. I can do $92.52 today. Would you prefer EFT, or Cash on Pickup?  😛
