Roll over protection

Southernlandy · Jun 2, 2014

Starting to actually think about driving my car once its finished, I've been thinking about some safety in the worst case scenario, my car rolls over. I've seen many 90's with external roll cages but I was just after a small roll over hoop to go inside the back so the roof doesn't collapse if it rolls over. (I've seen videos of it happening). As I want to keep the car fairly standard I don't want a large cage and this will only be on the road, no off-roading. Am I wasting my time or how likely is it that with driving on the road, the car will roll over and the roof collapses?

When i was looking at getting my cage i thought of just a hoop at the rear, but if you draw a line down from the hoop to the bonnet it would crush you into the dash/steering wheel in the event of a roll over.

If you were going to go to the trouble of having one put in, then you might as well get something that would actually work if you ever needed it. I think safety devices and protection and performance both do internal cages, they will take up some room though. They are not just a hoop in the back though

Thinking of safety, maybe more common would be someone colliding with the side of the land rover, have you thought about or fitted rock sliders or similar?
If a euro box was to hit the side there is not much to stop the occupants being squished until the eurobox gets to the chassis.
+1 on more than just a hoop, roof + dash + head = lots of aspirin if you are lucky.

If you intend to compete, then fit a roll cage.

If not, save your cash as it will just be a pile of bling adding loads of weight.

As for side swipes by other vehicles, you are in almost 2 tons of well designed box with a solid steel framewok underneath it, so a hit at 90 deg imeediately behind the bulkhead would be the only time you could finish up with a spare engine sitting on your knee!

Anywhere else and the ally box and steel chassis would form a massive crumple zone, as would the engine bay and bulkhead.

Even with a full roll cage, turning over at competition high speed certainly gets the sphincter twitching! I'm too old for all that now though

I strongly disagree, have a look at the b pillar and how its fitted.
No strength there and there is a good bit of passenger to be a crumple zone before the cars crumple zone gets to the chassis.
