rollcage legality

[h8wrxs]

first up, ive done a few searches on here and cant find quite what im after

(i know its not toyota but...) my evo 2 had a half cage in it when i bought it, i pulled it out as it wasnt certed (previous owner had it legal through msnz and car clubs etc)

after i took it out i noticed just how much it stiffened up the body and did improve then handling

anyways ive decided i want to get one put back in, i knwo you can get half cages certed but what about full cages that go right along the roof and down the windscreen, behind the dash etc

can you get them lvv certed or do you have to do it through msnz? and with half cages can they be welded in or do they have to be bolted?

i got really confused reading the msnz site so thoguht id ask here (might have had a few beers in me too)

A full rollcage requires homologation to MSNZ, a LVV MSNZ authority card and a competition vehicle logbook, also race seats and harnesses must be fitted.
A minimum of 2 events a year is required to keep the authority card current. (Authority card is required for warrant of fitness).
Thats the basics of it.

Cages must be welded in, no bolt in cages are legal as far as i know, even for WOF purposes.

[h8wrxs]

i had a feeling that was the case, hoped it wasnt though

was hoping you could just get it certed and not worry about the msnz and havign to compete etc

that was the whole reason i cut the old one out

Cages must be welded in, no bolt in cages are legal as far as i know, even for WOF purposes.

Cages can be bolt in/bolt together they just have to be done the right way. my suggestion would be to PM Leon and he can full you in with the cans and cants

You can have a bolt in half cage or a welded in half cage. You can then go through either LVV or MSNZ.

There are oodles of diagrams and stuff in the MSNZ rule book showing you what joints you can use where.

My personal opinion is that I'd go for a welded in half cage if you're after stiffness and relative ease of use.

Get it done through a MSNZ recognised cage builder, and get him to do the paperwork on the cage. This means if you *want* to, you can then roll up to a trackday or something like that, produce your paperwork, and there's no drama.

Additionally, I think that having the MSNZ paperwork (as compared to having only LVV cert) will likely add value to your car come sale time, as it means that people who race cars will be more likely to want to buy your car.

That is correct for this car, however you can get a full cage certified if you have a full chassis.

its cheaper to get it MSNZ certified. if it had a MSNZ cert before there isnt any reason why it would fail.....

[h8wrxs]

so can you get it msnz certed even if you arent a member of a car club? i was under the impression you had to compete etc to get them certify it

can you recommend any msnz recognized cage builders in chch?

[touge_ae101]

you don't have to 'compete' as such, just complete 2 manz sanctioned events per year. not hard really when you consider toyspeed megameet was msnz sanctioned and other pretty laxed track days are too. so nothing too excessive.

oh and yes you do have to be a member of a car club. but club memberships are really cheap

not sure on half cage but one big draw back of going to a full cage is the need to have fixed back seats and wear harnesses on the road. bit of a PITA for daily driving i'm thinking...

[h8wrxs]

but isnt it illegal to wear harnesses on the road anyway?

[touge_ae101]

not if you have a logbook. just means you have to remove the standard seatbelt

You can have a bolt in half cage or a welded in half cage. You can then go through either LVV or MSNZ.

so does that mean that you can put in a bolt in half cage, and as long as its LVV cert'd you can get wof's without issues?

[Truenotch]

Replace "Logbook" with MSNZ Authority card and that becomes correct.


With a half cage an Authority card isn't required, but it needs to be homologated to be able to compete at events. I'm pretty sure you wont require a cert if it is homologated, and it should be legal to use standard seatbelts too - but the water is quite muddy in these areas.


If you aren't planning on doing events it's a lot harder to keep legal without an LVV cert... To run with an authority card you need to do 2 events per year (easy enough) and this makes it legal to use a race harness, provided it's still current.

It's all very simple, but is hard to explain over the internet (as you may be able to tell).

Anything that is LVV certed will go through a WOF with no issues.



The question is whether a half cage required an LVV cert or not... I've heard arguments both ways. Since the structure is not in front of the drivers head, a half cage should be legal without certification.

Can't be bothered reading the LVV guidelines to see if they demand a cert for a half cage - can anyone else enlighten us?

The story I've heard is that you can have a bolt in cage, if it's a half cage and the rear seats are removed. There's so much stories floating around it gets really confusing.

Don't need a cert for a half cage - bolt in or weld in.

It just has to meet the requirements in the VIRM ie:

1. each seating position is fitted with an effective head restraint

2. the bars are positioned:

-behind, following a plane extending upward, parallel to the back of the backrest on the rear most seat, and

-in such a way that the head restraint would provide protection from head contact with any bar section during a crash

Basically as long as the rollcage is padded in every area that you could potentially smash your head open on and none of the bars extend forward of the front seat backrests (rear seats should be removed - common sense) you'll have no trouble. If any of the above requirements aren't met - you need a cert.

[Truenotch]

That's easy then.


So the best way to go about running a half cage in a road car is to:

1: Build a half cage to both MSNZ and VIRM (Wof) specs

2: Complete MSNZ homologation & get a logbook

3: drive on - get your logbook signed twice a year by a scrutineer and all is well.


You could do it without homologation, but that means it's not usable for any permitted events.

i have a mate that does mint fab work and does MSNZ spec 6 point basic weld in for $1100 homologated, so id imagine a couple hundy cheaper for a half cage if your interested man. let me know and il sort it out

[touge_ae101]

does anybody know someone in lower north island to do a cage?? everyone in palmy is at least 2-3 months away....i want mine done within the next month. would travel to welly to get it done.

[cogent]

octane automotive in palmy did a mint job of my halfcage.
