    It'll look ghey but it'll be legal.

    Hardly any mods are "legal" including adjustable suspension arms, HIDS, removing AIV/EGR, coilovers, larger intake, most fibreglass parts, pod filter, going too large or too wide with your wheels, lowering the car too much, having those Altia style rear pages in anything but red... You get the picture.

    I've been pulled over a couple of tines for "random" breath tests in the zed and never been hassled about my carbon bonnet.

    Any bonnet that has not come from a car manufacturer and has not been subjected to crash testing will require an engineers certificate to demonstrate that prototype bonnets were tested to meet with ADR rules and designs.

    they are in Queensland at least. Was defected for it, and transport department confirmed that they are illegal. Far less likely to get pulled up for a colour coded Fibreglass front bar than you are a CF bonnet though

    Bodykits are generally fine, so long as you can't see carbon

    Rubbish.

    Aftermarket panels are either legal or they're not.

    Anecdotally speaking just as many people have been defected for fiberglass bars as have been for carbon bonnets.

    I'm speaking realistically. Yet to hear of someone being done in NSW for a glass kit. CF bonnets, sure.

    Agree with Rob...realistic is completely different to legality. If legally speaking its illegal to have glass bars or cf bonnets, then thats the the end of it lol as far as I'm aware they are illegal in VIC aswell

    Can only think of a handful of members (myself, shifter, Steven with the v8, ports) running carbon hoods in NSW. Not aware of any of them being done.

    Remember road safety acts differ state to state.

    maybe legal?

    Are we light vehicles? There doesn't seem to be a reference to light vehicles in the vehicle standards/vehicle categories document http://www.comlaw.gov.au/Details/F2012C00326/Html/Text#_Toc326158540

    This is a good source

    2.7 FIBREGLASS

    2.7.1 Strength and Thickness
    The thickness, of non-intrusion panels, with gel coat removed, must be at least 3.5mm. Bonnets and guards are examples of non-intrusion panels.
    The strength and thickness of structural components such as floorpans and bodies that incorporate seatbelt anchorages, door hinges and latches etc., must be certified by a signatory. The fixings for replacement fibreglass panels should have the same positions and must have at least the same strength as the fixings used for the original panels. A combination of steel and
    neoprene washers of a minimum 20mm diameter should be used with all fixings.
    Seat and seatbelt anchorages, door hinges and latches must only be affixed to fibreglass panels, floorpans or bodies that have been reinforced to take the loads such components are capable of generating both in normal use and in a crash.

    Same document states

    4.3 CUSTOMISED AND REPLACEMENT PANELS
    4.3.1 Customised Metal Panels
    Body panels may be customised (e.g. to fit alternative lamps), provided that the structural integrity of the body is not adversely affected and the vehicle continues to comply with all relevant ADRs.
    4.3.2 Fibreglass and Other Composite Replacement Panels
    Original bolt-on metal bonnets and mudguards for pre 1971 (ADR 10) vehicles may be replaced with fibreglass or other composite panels that comply with sub-section 2.7, providing the modification does not increase the rigidity of the front structure of the vehicle and the collapsibility of the steering column on ADR 10 vehicle is not compromised. The catches and/or the design of the replacement bonnet must prevent it from being propelled through the windscreen into the cabin area in the event of a frontal collision.

    Yes it says pre 1971 but I think the point is made that they don't distinguish between carbon and composite panels. Thoughts?

    Hard to find anything definitive though there are so many documents and revisions

    And does anyone else find this interesting? Or am I just pissing in the wind here? There's always so much heresay and "my mates' brother's cousin..." when these topics arise -I'm interested in what the legislation actually stipulates...
