You can either bolt or weld a rollcage in.   With a buggy it's easier to bolt, not much space, and the tub is also in the way of easy mounting points.  You need a plate on the "foot", and a corresponding plate underneath to spread the load and "sandwich" the floor.   If you want it to be functional and not just for show, then you need some stays (diagonal bars) properly mounted somewhere to the rear, rear shock mount area  is a good point. 

cheers for the help guys 

TBH unless the car's floors are seriously strengthened with box-section steel etc. any roll bar or cage attatched to it can only really be considered a 'show cage' because standard floorpans are quite thin sheet steel and replacement ones even thinner. Also there's very little securing the rear corner of the 'pan (where most people mount the roll bar) to the rear chassis/torsion tube, just a couple of spot welds.

A 'traditional' roll bar, the type Flatlands etc. sell just mount with a small plate with one bolt at the bottom usually through one of the body mount holes, and with one or two bolts through a plate through the side of the body tub. This would be OK as a seatbelt mount bar (which Jas actually describe it as in their price lists) as long as it's bolted to good sound thick fibreglass and not 40 year old cracked, brittle and manky chopper-gunned stuff, but nothing else.

Dave is right there, buggy and safety are not two words that really go together, and that is most of their  attraction and charm, especially in the modern risk-averse world.  At least in the buggy you are in touch with the road and the elements, and in control of your own destiny. 

My New Buggy has a great roll Cage lol 

I actually cringe at the design of a lot of so-called 'safety cages' and marvel at the close proximity of a lot of tubes to people's heads. A reletively minor shunt could send a head hitting a tube at something like 30mph, easily enough to kill. Likewise people who fit rear seats into Buggies with the rear passenger's faces at roll-bar level...scary!!!

I'll take my chances with a simple hoop and no seatbelts so I can 'bale out' if need be.

Hitting a speed bump too fast or a not-so emergency stop in this Manxter could easily kill the rear passenger...

Theres a cage on mine thats more of a show cage and obviously not going to take much whack, but what happens when you bale out and smack your head on the kerb/lampost instead? Surely you'd be better off with belts?

It's safer than a motorbike, I don't do a great yearly mileage, I drive sensibly, you're much more aware of other road users in a Buggy and it's tangerine so quite noticable.

I'll take my chances.

Ive got to say that mine has a 'show' hoop and it did remarkably well when i stuck the buggy in a tree! but having said that i think i might have used up that chance so a more substantial option will be looked into.

even she looks scared !!

Its all relative i think, if you have a bad smash in a buggy a cage wont make any difference, a low impact then it may well help,

this was nicked from Facebook, the blokes head would be ok, but his legs might sting a bit    i am sure its only a mock up anyway 

Hi all,

Over 90% of all vehicle to vehicle conflicts occur at or below 30mph.

So a full cage (I actually call it a hood support cage), beam strengtheners, proper fitted belts, collapsible steering column etc will help for most bumps you may be involved in.

Not sure how effective a single hoop is in a collision as I have always run full cages, more to help re-stiffen the chassis etc as well as add some protection.

Obviously at higher speeds your in the lap of the gods but as Dave rightly says its about defensive driving techniques like they teach motor bike riders. Looking three cars ahead for breaking, peripheral vision, etc.

Spot on Chad, that's the reason I always mount the seats it a reasonable height, I cringe slightly when I see bucket seats bolted straight to the floor and 'layed back'. I guess I've driven vans for too long, I do like a good view...
