[kingmick]

[love ke70]

no, i dont want to be lucky to be alive, i want to be alive i was prepared.
wasnt really clear...now back to your box smartarse

Care to elaborate on the half cage being deadly?

My understanding as far as rego was in line with what blake said above, i'm not interested in removing the front 2 points all the time, nor driving with a 6pt all the time (done this, no fun in a ke20, much head hitting is done when hit potholes), and i want it road legal.

With this in mind i'm seriously considering a 4pt half cage, i've already messed myself up once on a bike don't want to do it again..

also dude, if you plan to do any sort of cams racing you have to have a FULL cage, no half cages allowed....

The main problem with half cages is they strengthen HALF the car, unfortunately its not the half you are sitting in......

Keen to see the finished product mate.

I had Bonds make my rear 1/2 up and was happy with that.. Want to add the front half sometime this year just interested to see how it gets around the dash etc and what kind of head room you have left.

I'll probably only be interested in club level events where you probably don't need a cage to start with, as opposed to serious racing.. so while being fully cams approved would be nice, its not the end of the world for me

The main hoop is near your head at least, between the front of the car and the main hoop should give you some sort of roll protection.. while its obviously greatly inferior to a 6 pt, its certainly better than nothing at all i figure, particularly in a ke20

I was under the impression that the half cage would be better than nothing too (for rollover), but a few people have eluded to otherwise. Apart from the potential head contacting bar issue what are the other dramas? Disregard the fact that rear seat passenger can't be carried.

[WDE_BDY]

In an accident the force has to go somewhere, the 1/2 cage prevents the rear from abosorbing it so all the forces are concentrated in the front half. Yes in a rollover the bar will hold up the roof above where your head was, but is your head still there or is it further forward where most of the impact is now concentrated?
One other thing to consider, how safe is a cage when using normal belts? The range of motion they allow in order to slow your body down puts you much closer to impacting the cage than harnesses will allow. I would never have a vehicle with roll protection and regular seats belts, its either full protection (harness, race seats, cage and helmet) or the factory setup. Mixing the two is not a good plan as they take incompatible approaches to injury prevention.

not a prob mate, it will deff be in b4 wakefield, so you can have looksy then,

A bit of head bendage (lol) is likely, but being bent over a bit by the roof is a damn sight better than being flattened by it i figure..

I plan on running a harness with or without the cage, but obviously not a helmet on the street

[takai]

Be aware that with harnesses doing things like headchecks and reversing becomes a chore.
personally i would run both but not use the harness on the street.

A good bolt in cage should be no diff to a weld in.

Also the forces involved in an accident are far greater than that of the car body flexing... so a cage has no effect to the flex of the car id say you would be stuffed in an accident.

nah, not really.

bolt in cages are the cheap and nasty (although not always cheap) of doing a proper (weld in) job.

they help, but offer nothing near what a weld in will, if not installed properly.

its not just a matter of bolting it in, but you have to re-enforce the parts where its being bolted in, and with the material you've used doing that, you would've been better off with a weld in.

Another point with a half cage, it MAY give you more protection in a rollover but rollovers aren't that common. Side or front impact they can be a lot worse for you.

either way, anything safety related where there were none b4 has got to be better in some way or another,

a half cage is also usefull as it gives you a good solid harness mount too,

the weld in cages were quite a bit more $$$, so for basic club level motorspot, i feel the bolt in will be highly sufficient,

also with the bolt in, you do have to weld in plates to where it bolts to, so its not held together by 1mm pressed metal sheet

You might want to consider _not_ using a harness without a cage, because if your roof does collapse, you _want_ to be able to move a bit. With a harness on your head will be there to help hold the roof up, which isn't a good thing.
