I was pulled over on the way home by an unmarked commonwhore trying to get me to race em and they went over the whole car and thankfully didnt find anything to book me for but they did warn me that although the bonnet isn't illegal, it is a liability in an accident if the carbon fibre shatters and causes damage/injury.

carbon bonnet isn't illegal? i thought it was? :confused:

It is illegal only for the cars that is sold in Australia....like the S14 200SX,REX,Corolla etc....

for import car, police cant do anything with it...just tell them it come with the damn car...

Hmmm...so it is not illegal for our skylines to have a CF bonnet here in queensland? I also heard from people that its illegal to have a CF bonnet here....Pls advice~~

Basically I posted for this reason as I've heard conflicting opinions also and have had bonnet for 4 months now on daily driver.

i dunno still, before i went out and bought a carbon fibre bonnet i would want solid eveidence that proves that its not illegal, because as we all know 1 cop will tell you 1 thing and another will give u a ticket for the same thing and let you deal with going to court and proving it. hence wasting your time and $$ anyhow. thats what i hate, they dont get in shite for handing out defects on car if its not true and u gotta prove it. (e.g the carbon bonnet).

I would also try ringing up your insurance company and ask them if they will cover you if you had a CF bonnet...they should have a fair idea of whats legal and whats not. That said, there has been a handful of ppl that have been defected for CF bonnets in the past so go figure..??

If it's not standard, you can get done for it!

pretty much.....even with mod plates, you can be fined.....what one cop says doesnt speak for the entire force. The majority will fine you for a cf bonnet as they dont meet crumple requirements etc.. You were very lucky not to be fined!

I spoke with two modification certified mechanics and both told me that if they latch and hinge in the correct places, there is nothing wrong with them and no plate is required.

From what i've been told by both RTA and Police is that they dont "shatter" correctly in a crash and that the shards of fiberglass/carbon can be dangerous to the people in the car and around it.

Is it 100% carbon anyway?  Because if not you would be getting done/warned for your mostly fiberglass bonnet with a final layer of carbon on it so it looks pretty.

Mine is 100% CF, but the cop said it would be illegal either way because it affects the crumple zone and the bits of CF will chop pedestrians up into teency pieces, or something to that effect.

someone should start making carbon/kevlar mix parts...

Entire cars are made out of this stuff (Holden Giocattolo most notable car made locally from it) and when it gets smashed, the kevlar holds it all together (well something does, i'm pretty sure its the kevlar) and it smashes, but holds its shape, pieces don't go flying off etc...

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

    • Is there a way to adjust all of the pedals in an R32 GTS-T? they all sit even, but seem to be a little high for my liking.

    • The engine stuff is Greg Autism to the Max. I contacted Tony Mamo previously from AFR who went off to make his own company to further refine AFR heads. He is a wizard in US LS world. Pretty much the best person on earth who will sell you things he's done weird wizard magic to. The cam spec is not too different. I have a 232/234 .600/603 lift, 114LSA cam currently. The new one is 227/233 .638 .634. The 1.8 ratio roller rockers will effectively push this cam into the ~.670 range. These also get Mamo'ified to be drilled out and tapped to use a 10mm bolt over an 8mm for better stability. This is what lead to the cam being specced. The plan is to run it to 6800. (6600 currently). The Johnson lifters are to maintain proper lift at heavy use which is something the LS7's supposedly fail at and lose a bit of pressure, robbing you of lift at higher RPM. Hollow stem valves for better, well everything, Valve train control. I dunno. Hollow is better. The valves are also not on a standard valve angle. Compression ratio is going from 10.6 to 11.3. The cam is smaller, but also not really... The cam was specced when I generated a chart where I counted the frames of a lap video I had and noted how much of the time in % I spent at what RPM while on track at Sandown. The current cam/heads are a bit mismatched, the standard LS1 heads are the restriction to power, which is why everyone CNC's them to get a pretty solid improvement. Most of the difference between LS1->LS2->LS3 is really just better stock heads. The current cam is falling over about 600rpm earlier than it 'should' given the rest of my current setup. CNC'ing heads closes the gap with regards to heads. Aftermarket heads eliminate the gap and go further. The MMS heads go even further than that, and the heads I have in the box could quite easily be bolted to a 7.0 427ci or 454 and not be any restriction at all. Tony Mamo previously worked with AFR, designed new heads from scratch then eventually founded his own business. There he takes the AFR items and performs further wizardry, CNC'ing them and then manually porting the result. He also ports the FAST102 composite manifold: Before and after There's also an improved racing crank scraper and windage tray. Helps to keep oil in the pan. Supposedly gains 2% power. Tony also ports Melling oil pumps, so you get more oil pressure down low at idle, and the same as what you want up top thanks to a suitable relief spring. There's also the timing chain kit with a Torrington bearing to make sure the cam doesn't have any thrust. Yes I'll post a before and after when it all eventually goes together. It'll probably make 2kw more than a setup that would be $15,000 cheaper :p
    • Because the cars wheels are on blocks, you slide under the car.   Pretty much all the bolts you touched should have been put in, but not fully torque up.   Back them off a turn or two, and then tighten them up from under the car with the wheels sitting on the blocks holding car up in the air.
