Thread: half cage and side intrusion bars question?

hey guys

im a bit lost on what iv been told and this will decide wether i buy this car or not

it is certed for half cage and side intrusion bars, but iv heard that i cant do events with them, example, superlap etc etc witch is what i want to get into hence why i wana buy this car, and i can drive to events and back seeing its certed for it, what are my limitations with having only a half cage and side intrusion bars?

any information will be muchly apreaciated guys

cheers kieran

Yeah you're in a tricky situation with certain events where you'll either need a MANZ approved cage or no cage at all. To some it might seem backwards but those are the rules.

I know Slash was declined for Superlap because he had a certed half/bolt in cage.

I've seen speedway club guys turn up to MANZ hill climbs and get declined because their cage isn't MANZ approved, yet others are allowed to race with no cage and no safety equipment beyond what it came with from the factory.

thats so dumb! this car wouldv been the perfect start for what i want to do! and super lap will be a must! would it be hard to take a half cage and intrusion bars out? if its welded in?

A half-cage is essentially as good as no cage, in terms of event entry... with the exception of convertibles. Side-intrusion bars on a half-cage are really only good for peace-of-mind, from what I understand (Leon could confirm - I don't have my rule-book on me here at work).

You can do clubsport events (bar rally/hillclimb where it's specified in the entry requirements) without a cage, or with an approved half-cage. Just not national grade events like Superlap and SS2000.

You can get the cage extended. Would be a waste to just bin it.

so i would still be able to do a few events, but superlap is my one main event i wana attempt, but doing some events would be still waaaaayy better than nothing i guess so got a lil up there, would be nice to do hillclimbs but unless i have up and get a cage done properly that not gna happen

would i be able to do just plain old track days??

Yeah plain private track days are sweet.

Leon will have alot of good advice for you on this topic.

Take a look here at the diagram on page 45. A roll bar (half cage) is essentially as useful as a none in a closed-top car.

A half-cage with side intrusion protection is pretty much an easy way to get "relatively" full protection, without the requirement for a MSNZ authority card.

the cage was built by STR fab down the concorse that is no longer open.
the cage would not be homoligated as it was built before the rule about the main hoop sizing that came in this year

Hard to know from the pictures. The way its mounted to the floor/base plates etc are important.

To be honest when it comes to half cages like that its usually easier and you end up with a much better (and safer cage) cutting it out and starting from scratch - if a full cage is on the cards in the future to step up to some bigger events.

More than likely, the cage would need to be homologated (with a log book), then if you wish to extend to a full cage, you need to get approval from original cage builder (if you know who that is). Get as much info as possible about the cage, you`ll need build photos etc. Good luck.

so for that half cage, even though its certed for the half cage id still need a log book?

log book is only needed for homoligation.

so because it was done before that rule/law came in it wont need one? i think im getting the hang of this lol

because of the new rule it would not pass homoligation. with homoligated cage you are required to have a log book witch is stamped at events. you need to do 2 events a year to get a wof afaik. you also need a race licence to get an authority card witch lets you drive it on the road......... i 90% sure

so i wouldnt be able to drive it on the road because i dont have race licence yet?

there is no issue because its certed.

you need a race licence to apply for an authority card when homoilgated

sorry got myself confused there! because its certed i can drive it on the road not having a race licence and log book? can still do track days etc but just cant do some events?

you got it

would it pass cert again if i go for a recert for a bigger motor etc with that same cage?

unless you are going to get into and do manz events homoilgation is a waste of money as race licence and authorty card need to be updated yearly and cost around $100 each

dont see why not it was only certed mid this year
