half cage

[bluemaumau]

if built by a professional,

good or bad,

will naver be as good as a full cage, but is it worth it?

not for me btw

[Distrb]

for what purpose?

[postfach]

Better than nothing if you roll, at least the roof won't completely crush in, probably gives a little extra side impact protection, but wouldn't be a heck of a lot I don't think

[bluemaumau]

street/mild mottorsport, i think hwe shouldnt bother , as its not like hed be attending 5+ events a year.

someone on here seemed to think they were pointless, cant rememeber who, did a search but didnt find much

[bluemaumau]

sorry itll only ever see drift/circuit(this mainly)/drag racing + street

[Caveman]

What car is it for matey?

[d1 mule]

cant hurt. extra safety+stiffer chassis+not a paain like full cage if used on the street gotta be good.
i had one in my ae85 was good

[strx7]

price of half cage vs price of neck/spinal chord/possibly life.........

[Mr Revhead]

half cage does squat for stiffness.
you have a roll hoop, and 2 backstays. how will that stiffen the car?
it may stiffen a part of some cars if it attatched to the roof


what car will it be in? a full cage doesnt have to be a pita to get in and out of.
but if he is realisticly only going to be doing 2-3 events a year he may not need to go that far depending on what those events are.
if drifting is something itll doing be lots of, then id go full cage.

This one of those things that can be debated from many sides.

I've got a half cage in my 14 and yes its street driven. Now the thing is how cheap is the half cage?? Is it a bolt in or weld in?? Is he just after it for the "look"??

If its well priced/cheap and its a bolt in and its more for safety than "looks" why not??

How ever if its a weld in or he just wants it for looks and or its expensive then no I wouldn't bother.

The other question is has he looked at other mods instead of the half cage ie: other suspension parts??

[Infinite]

why waste money on a bolt in when motorsport will tell u to go get a weld'd cage......... im street driving my curren with full cage and its gona be a &#*@ to get in and out of but oh well thats life....

Personally.

If you're going to do any motorsport in earnest I would get some form of cage. It's cheap insurance considering it could reduce an otherwise serious prang into bad prang. Sure it won't help in all situations, but it will help in some, and doing motorsport exposes you to a who heap of situations you wouldn't normally be exposed to.

I run one in my AE85 as it was to allow me to do some more events than no cage (although it seems now that this might not really be the case). As far as stiffness goes. I'm not sure about other people, but it was defintely noticable in my car. The whole back end was much improved in feel when I had the cage in there. I won't go as far to say that it makes a remakable worthwhile improvement. But it does make a difference.
My cage is the main hoop, back stays and side intrusions. I would expect that the longitudinal stiffness has improved, but couldn't honestly say.

Considering all the paperwork, WOF hassles (if you can't find a nice knowledgable WOF man), insurance considerations, cost, and incovenience, I wouldn't install one in somethat that was a daily with the "odd" event. But if you're planning to try and go to a few events (more than two or three a year) and at least one of them is a circuit event I would recommend a cage.

Things to consider. If the front half of the cage can be made as bolt in. If done correctly, this will give you a full cage for events where one is needed, but allows you to run half on the street for convenience and certing issues.
The thing I don't know. Is the log book and authority card requirements for a bolt in front. If they're the same as fixed full cage, then you might as well go fixed full cage.

Bolt in half or full cage is ok for MotorSport, if you do it right. The reality is that they're such a hassle to remove and refit, that basically nobody ever takes their roll protection out more than twice anyway

A half cage is a lot better for your safety than no cage if you're playing in cars.

If you're going to keep driving the car on the road, a half cage is in my mind a good compromise, as you don't have to go to using full harness belts when you're using it on the road. Which means also, no requirement for a MSNZ authority card.

If you're going to get a half cage, you will need to get it homologated, and also get a logbook ($103.50 total cost currently)

That's what I have seen on Porsches that come from overseas for targa, I always wandered how come they get away with bolt-on cage...

[bluemaumau]

i think its a bad idea also.

itd be a welded in half cage into a c33 laurel

[Trls250s]

I use to have a A31 cefiro and had/have a lot of mates with C33 laurels.

They tried to take there C33's to puke but werent allowed cause they have no door pillers. I'm not 100% but they were told they cant do any track time without atleast a half cage.

Something else to consider...

[Caveman]

Bolt in cages are just as good as welded if done properly. Agree with leon major pita to remove. Quite a few guys with miatas run bolt in cages. No problem to remove those tho lol

If your not going to run rear seats, parcel tray, etc then it would be good to have a half cage. Dont expect it to be under $1000.

Have the hoop as far forwards as possible over the drivers head, and use harnesses to strap in

With the way I crashed my last car, a half cage would not have protected me. Just keep that in mind

[bluemaumau]

yup thats what im telling him dylan, he reckons he can get it done for 850

sounds dodgey to me.

good point Trls250s.

cheers everyone, pretty much answered this one

[d1 mule]

i got my half cage done for $800 inc homologation and log book with main hoop 2 back stays with one cross bar, transem bar, harness bar and a cross bar between the transem and the back stay done by PETES CUSTOMS in chch excellent quality.
iv got mates who have had full cages done for >$800 all depends WHO you know...

Just remeber that for it to remain road legal you need to keep all bars no further forward then the back of the headrests.
