So your saying that race car safety is the same as road car? My guess, if that rig had normal seats and belts, driven on the street like a normal person would, a stock rig would do a better job of protecting occupants.

Most race car setups severely limit the driver movement, with good reason. A large percentage of occupant protection comes from gear that the driver is wearing, head, neck, arm restraints, etc, a relatively lengthy dressing process. Most road car drivers that I know, it's like; shorts, t-shirt, flip flops, lets go, want to have the freedom to move, reach their drink, etc. Safe road design is a very different thing than a race car.

No that's not what I'm saying, and you know it. Go back and read all the differences I pointed out.

I'm not going to debate whether or not risk to occupants is increased or not with a cage in an 80, other than to say that I don't believe a blanket statement of "it's a bad idea" is correct. Without question, a poorly designed cage can cause significant risk, but I don't believe for a second that it's impossible to design a cage for an 80 that will provide better safety for the occupants.

Not valid comparing the location of the B in your pictures with an 80 series. If you locate the cage support for the B on an 80 out of drivers harms way you will not be able to get into the second row. Also in an 80 cage you have no way (unless your are pinned down with a 5point) getting the needed clearance for the tube that runs above the door to avoid head contact. This is first hand info having hit my head more than once on the tube above the door opening with the seat down to the max. Having had a caged 80 I would not have it again on the 1st row if it was free.

I fully understand it's not an exact comparison. My post was not intended to say "build a cage like this and it will work", but simply a point of reference and one data point from a similar vehicle.

You'll also notice, I don't have a cage in my truck. If that's any indication of where I stand on the whole thing.......
 
I would think getting a cage for safety would mean you would also be getting a proper 5 point harness to keep your head somewhat stationary. This was my thinking when I had a cage and harness in a previous Jeep. I clocked my head a few times getting in and that was not fun.

There is a ton of room if you remove the headliner. Again, this would apply more to a mostly trail rig.

Why would you consider a cage in anything other than a trail rig?

I am a fan of hybrid cages, myself, or very tight Exos. I'm not one to discourage forward thinking, however.
 
I notice a lot of the people that are saying "bad idea" had a hillbilly cage in their 80 at one time.
Just because YOU had a cage built by Billy Bob, wasn't to spec, and wasn't certified, that doesn't mean that this certified builder can't build a safe cage. I believe he's asking for interest, not for your story of how your Gerry rigged, flux core welded pos came out. Give him a break, just because you don't know what your doing doesn't mean someone else doesn't.
 
I had a bolt in cage in my 86 xtracab, was a bolt in job.purchased it from downey offroad back in the day. it survive a rollover to the side starting on the passenger side ending on the drivers side. it kept the outside outside and the people on the inside safe.Yes it was fully padded.I finally removed it not because i felt it wasn't safe but because it takes up a lot of room in the cab .That was ok when i was 28 and 175 lbs but at 57 and 250 I want the room back and i no longer go rock crawling so no real need.Not so sure i would want to test it end over end at speed . but it was ok for what I did. Install them if you think you need it ,But i would not put one in just to be cool.

That is good comedy right there!:hillbilly:
 
What about a braced tube across the ceiling behind the driver seat? Too far back to hit your head, but far enough forward to keep the roof from crushing you when upside down if the A pillars go. Some convertible sports cars have pop up versions of this that activate when the car goes too far off level. There's video of one of these deploying when a guy goes upside down at over 100 on the autobahn. Not a scratch.

Valid point, but even the most legitimate, certified roll cage is not certified for use with a naked head and a 3 point seatbelt.

They are certified for structural integrity in a rollover in off highway situations.

If someone wants to make a well-engineered cage for an 80, then by all means go for it. Just PLEASE don't try and market it for the driver who uses it mainly on public roadways.

Some got started early on 4/20 celebration;)
 
I am not very tall, and unless you are a 5'3" 80 owner, there will be many of days, of you bashing your head just getting in it. 99% of the knuckle heads here are not doing Dakar Baja or any other thing near that, and putting a bolt together cage in a FJ80 with substantial strength will take up what little room we have, yes it will give you safety, with all of the other safety, items needed to complete the value of it, but hey it is your time and money and cruiser, life do what you want, I am not seeing a benefit, with out all of the other stuff JMHO

I'll just leave this here.

IMHO, the 80 body is not the tank that we have all led ourselves to believe. A cage is not a bad idea if it can be pulled off in a safety-minded fashion. I bought this truck as a donor vehicle. The PO flopped it off a 15' bank. He broke his arm. Considering that there is not a straight panel on the whole truck and the fact that the roof came down enough to smash into the driver seat headrest, bending both headrest posts, he's lucky he lived.
