no, but it's getting to the point that NOTHING is legal nowadays
It seems to me that a lot of your rules are designed specifically to discriminate against non-aus manufactured cars, so are probably back-scratcher laws. Unfortunately NZ takes its cue from Australia a lot of the time, so its starting to get that way here too.

Any idea how much the FRP ones would weigh?

3 x as much, ie: 21kg
Not necessarily. Looking at the CF doors in the picture they look like they are only for show, so they have a layer of fibreglass on the inside of the door already (opaque white looking layer on the inside). In my view they should weigh less than 21kg. I'd guess at about 13-16kg from what I've seen on other doors. Or is there something that I missed?

Safety? *SIDE INTRUSION* I'd love to see figures on crash tests of the various doors. Stock vs CF vs RFP.
I'm all for cutting weight....as much as possible. But there?...the doors? (well maybe the passenger) It would be like cutting the arse out of your best pair of jeans, putting on a Gay Pride T Shirt & watching the Mardi Gras with you hands tied to your ankles, you could get....""hit"" from any angle

Ive always found the best way to lighten a Soarer is to remove the engine/trans/ecu, and slip it into a S13.
That way all the good stuff you'd waste time removing from your soarer, uis already done for you, because Nissans have no l;uxuries to start with!
And you solve the problem of crappy nissan engineering.
2 for 1
HIGH FIVE!!!
No but seriously, start with something else if you want light. Soarers just arent light cars, thats how they are, and surely, for the love of god, would you really want you or your girlfriend to be involved in an accident with CF doors for the sake of saving a few kgs??
If your planning on a roll cage, then maybe, MAYBE it might provide some protection.

There is probably a reason these things are illegal or will be illegal soon. They are not safe on the road. If it is a drift or drag car on the other hand then yes it is good too lose as much weight as possible and these doors and similar bonnets are good ideas.
But with so many trees and power poles on the street it is not the best idea.
I have heard that the carbon fiber bonnets will chop a pedestrian in half (well not exactly but will damage them).

Wouldn't do them much good if you hit them over 40mph either, I don't disagree that they might offer less protection, but it can't be that much carbon fibre after all is a very strong naterial(just try cutting some)

I have the impression that carbon fibre can shatter under impact creating nasty shards and slivers that would do terrible things to occupants. In a military situation I have been in where carbon fibre has shattered from impact it had to be cleaned up in much the manner of a toxic fragment such as asbestos.

Having a close look at the CF door pics, I don’t think it will save much weight. It appears all they have done is cut away the outer skin of the original door and replaced it with CF. The inner door remains.
That would only save a few Kgs. When you put back the speaker box and speakers, door locks, window winder, mirror, door panel, wiring, and switches etc etc it will get back to almost original weight.
I don’t think CF panels are illegal as long as the integrity of the structure remains. However they have removed the side intrusion bar, so it is definitely illegal.
The CF bonnet ($2000) is your best value $ per Kg weight saving.
I believe the average buyer of this door isnt going to put the accessories back into the door, hence why they also sell acrylic windows to replace the glass ones + winder. I'm guessing they would expect you to just put a plain flat cover on the inside, with maybe a simple grab-handle and thats it.
I would say this will only be useful for those building track-only drift/race cars. If you are doing it for show, it would be cheaper, safer and look just the same, to put a layer of CF over the original doors.
ooh, look at me, i am playing the safety card here. Must be getting old ;)

Hey Dominik, how have you been? Yep, long time between threads. I was only trying to say that it would only be for looks as there would be not much saving in weight. If it was for track only, just remove all the parts on the door and replace glass with the acrylic windows. Then use the money towards to a supercharger from Neil. Then you don't have to worry about the weight.

FWIW re carbon fibre doors
I was looking at a new Porsche racing car the other day fitted with carbon doors. The doors weighted something 200 grams, really. The windows were made of lexan and were fixed to the door to form a single unit.
Structural contribution by the doors was however nil...zip, nada.
The roll cage expanded out towards the door opening and performed the function of anti intrusion structure.
The carbon doors albiet sexy as, were little more fairings.
