Save your money and avoid cusco. Their cages are a joke. The huge S-bends in the a-pillar bars completely neagate the point of even having a-pillar bars, and their clevis style bolt thrus for tube attachments are questionable at best. Not to mention they have ZERO triangulation, and no harness bar. Basically they're a piece of collapsible scaffolding that you can crush you skull on seconds before it impales you.

First post and already talking like you know your shit.

A cusco cage WILL hold up in a rollover...

How is letting the back corner of the roof completely collapse when hit there "holding up?" Looks like they were lucky that roll didn't keep going and hit further up on the roof.

The more you can keep the structure of the car from folding in, the more strength it provides in the event of a roll over. This is as basic a statement as the sky is blue...

AHHHH nope not as basic as you think you fucking moron, crumple zone! if crumple zone's were not beneficial in crashes manufactures would makes cars rigid like tanks. Allowing crumpling around rigid structure reduces the forces applied. Take for instance, your arm. It takes 4lbs of shock pressure to brake the bone. But because you have muscle mass, fat, and 2 layers of skin it takes roughly ~22lbs or more. Again what do you expect to happen? You increase rigidity of something on the car to protect a specific thing that means something else is going to give. That cage in the s14 protected the driver and he was in the drivers seat. If there was a front passenger he would of survived too. With that cage you can't really fit anybody in the rear so it is ok that it is crimpled to save the lives of the people in the front. But like i said before the cages only increase the survivability on crashes and roll overs, who knows, your knock off steering wheel hub might break and stab you in the chest. But to say that the car needs to be more rigid in a crash is just bad science. If a car is more rigid it will transfer all the kinetic energy to the most flimsy:IE YOU. If a car is more rigid you will hurt more from the crash and most likely snap your neck or cause major brain damage.



fucking idiot, I'm not even a structural engineer and that idea is what is basic to me.

You're right, you're not an engineer, or even have any common sense.

"Crumple zones" serve to slowly decelerate the car in the event of an impact. That's fine as long as you've got space to give. Unfortunately, the last thing you want to crumple is the roof right over your head. There is very little space to give, and any head impacts are usually VERY bad, so you want the cage structure up there to be as strong as possible.

I'd gladly take a little more G loading in a rollover compared to having my head and neck get crushed by the weight of the car coming down.

Go read up on the safety aims of cages, they are different than your average passenger car safety test.


I swear, fucking stupid kids. I wish there was a filter on this forum where you could only see posts made by people with an IQ at least one standard deviation above the mean.
