When you get into a crash, the carbon can shatter and do more damage if u hit someone.
I think there are a couple carbon fibre bonnets that are ADR'd which might involve them being laminated so when an object hits them they don't fragment into little ninja stars
cf gets nasty. when have a head-on it splinters into little javelins travelling a squillion k's an hour in every direction. bad.

Not sure where you guys are getting your information from, but carbon fibre is not a mythical fabric weave that all of sudden destroys anything in its path when it breaks. The actual carbon fibre itself does not do any damage, its more often the clear coat on top that has stuck to the carbon which will cause minor splintoring. Depending on the construction type (I'm assuming wet lay-up which most carbon items like hoods and bootlids are made from) will have the same properties as fibreglass when it's crushed or hit with force. You also need to consider that almost all hoods on today's market are not really made entirely of carbon fibre. They are a fibreglass skeleton with only a single layer of carbon on the top. You should also remember that all of the top motorsport categories like F1 and high end sports cars use carbon fibre (or a carbon/kevlar mix) to construct their chassis.

and this means....... it still shatters and stabs you like a gazillion javlins lol..... and that they are still defectable???? also don't trust that something is ADR approved, trust me when i say there are heaps of fake ADR shit going around..... especially in bike and race car helmets..... also i have never come across an adr aproved carbon bonnet either..... has anyone actually seen one that is legit????

No it doesn't shatter and turn into little tiny javelins. Having broken carbon items myself I can tell you that this really is a myth.

Also helmets come under the Australian Standard (AS/NZS1698) not ADR.

this shattering flying shards thing is not really accurate. the main problem with most carbon bonnets not meeting ADRs is to do with pedestrian safety. normal bonnets are designed to absorb the impact of a pedestrian you hit. carbon or fibreglass bonnets wont behave in the same way under those conditions. yes another small danger is it can brake at the mounts and end up like a flying disk, or it can break into sharp pieces but the big one is the pedestrian safety.

I think Blits bodykits in QLD make ADR approved ones.

      High temp brake fluid?

      By Komdotkom · Posted

      Reasonably hard, although I haven't run it with the new Endless setup yet. The old brakes were F50's on 335mm rotors and the car did a 1:40.6 at Phillip Island which is a reasonable time, I'm seeing high 600s on the temperature paint. A guy I know ran the Endless fluid at WTAC without issues and he was doing 1:33's I think (Evo) with a 355/332 setup. I don't get out to the track as much as I'd like but we put the car on the hoist and spanner check every bolt and re-paint mark everything, bleed the brakes, change the fuel, check the coolant system and re-bleed blah blah blah before every event. Motorsport is expensive, RB's are expensive so a couple of hours before an event is time well spent. It's also a net time saving because if you can keep your RB from self destructing it saves you time in the long term!

      Hello! I'm new here, I have an R33 GTST that is currently being finished up! Last year was pretty rough, blew two stock turbos so I decided to build the car. Has been down since November, but I get it back next weekend!

      Hello, I believe my car was imported to America in the 2000s by Kaizo Industries. Would anyone be able to help me find more info on them? I've only found all the basic stuff like that paul walker bnr34, them being shutdown by feds, just stuff like that. Any help would be much appreciated, thanks!

      HKS Vcam Step Pro Issues

      By believer · Posted

      I am using Motec M150.  I am not working on the car myself actually.  My workshop is giving all these info, they are quite reputable in the industry and are very familiar with Motec and RBs and have done a few big setups with VCam and single turbo on RBs.  In fact, they built and tuned my engine from day one.  But they are stumped with my engine at the moment and cannot work out how come the compression is so low with the VCam. They told me that they have now swapped in some Kelford cams (without the VCam) and can achieve around 130psi compression and the low end torque is better, but now the engine is doughy as.  It boosts and peaks at more than 1000rpm slower, with twin HKS GTIII RS, it doesn't get full boost until over 5000rpm. I have always thought the VCam was a bit disappointing at the low rpm. To a point I had to ride the clutch a fair bit to get up a small hill from stand still.  That was when I had a clutch.  Now changing to a 8HP, I don't have that luxury and this problem has become a major issue. I am beginning to think the VCam never work since the day it was installed.  Maybe it was just sitting at the most advanced point, that is why it went good at top end but very ordinary at the bottom.  Therefore, with the help of the Holinger 6 speed and paddle shift, as long as it was moving, it drove pretty good.
