Thread: half cage and side intrusion bars question?

so they wont make me get a log book etc now that the rule has been brought in.

no because it is not homoiliged<---------is only needed if

i understand now!!

thanks for being patient with the learner and thanks for all the info guys

You can LVV certify half cages (a regular cert), so they do not need to meet homologation standards. You can use them with regular safety belts and seats, and do not require an authority card. However, it is my understanding that unless it is homologated, it cannot be used in any events other than Clubsport Basic ones (and of course your regular open days like NIMM, etc)... events you could enter without a cage .

A full cage requires homologation, and the use of harnesses. For use on the road they therefore require an authority card.

Road worthy = Half cage, certed.

Clubsport events and higher with a cage requirement = Full cage with homologation and logbook (Authority card as well if you want it road legal). That car would potentially fail on homologation with the changes to the main hoop and thickness of bars regulations and unless the homologation paperwork was started BEFORE the changes, current rules apply. Talk to a scrutineer/MSNZ because if you plan on making a full cage out of that half, you may end up having to cut the entire thing out and start again.

With a half cage, you also must legally use seatbelts on the road, whereas with a full cage you have to have a logbook, authority card and you have to remove seatbelts entirely and use harnesses

90% sure is not good enough

To clarify.

The logbook has a picture of your cage, info on car, engine size, chassis etc. This has a copy of your homologation paperwork in it, which links to the cars cage, showing a scrutineer that the cage and car, are the originals that were looked at and are the same design
The homologation is a one off thing that says the cage is safe in its design, workmanship etc.
The LVV cert says that if you have a half cage, it is road worthy. (You can NOT cert a full cage)
The authority card has information on changes to the OE safety equipment. I.E seats, harnesses, cage, airbag removal, etc. This has your name, brands/shapes/designs of parts and THIS is what is required to drive a fully caged car on the road. You apply for it annually and have to have attended 2 MSNZ scrutineered events and have the stamps in your logbook in order to renew it.
The WoF is the thing that the dumbass at VTNZ gives you to say he checked over half of the shit on the checksheet and the car is probably safe.
Your motorsport license is required to get an authority card, and enter events. You need to join a registered car club to get a license

now i understand the full cage side of it, if i want to get a full cage there a HIGH chance it will have to be all cut out and started again from scratch..... im right? i hope. does anyone know why you can have no cage and race at certain evens but if you have a certed half cage you cant race at those same events??

Because they are a safety hazard in an accident.

look for a different car and put a full cage in it. Would work out cheaper i would imagine as opposed to paying more for that car and having to rip the cage out

My car has a half cage, it was MANZ approved, and has a log book. Plan on doing some club sport stuff.

The new rules state you must have a thicker main hoop than before.

The plan is to extend it in the future to a 6 point cage.

You might run into problems if extending as you'll have to re-homologate.... which you won't be able to do with the old-thickness main-hoop.... which means you might have no option but to hack it out and start from scratch

I already talked to Julian about this (MSNZ). He said I would be able to extend mine without using the thicker main hoop as the cage has been homologated before the effective date of the new rule.

Thats why I went ahead and got it all done.
