I reckon you could cut through carbon fibre like it's butter with an angle grinder as well... That said I want a rollbar (cause there's no such thing as too much protection) and I'm in no hurry to test how strong either the hardtop or the rollbar are.

IMO you are off your face using a harness without a rollbar.


true, but if a person cant afford both bits of safety stuff, best buy the one they can afford. The harness will also help hold him still - offering some sort of passive advantage to him ie he is concentrating on staying on the black stuff rather than doing an elbow/knee balancing act in a fruitless attempt to stay still while controlling the car.

good to hear - that way your less restrained body can flop around and allow your (helmetted) head to strike the rollbar, causing unconsciousness, coma and or death. Or worse - disablity and paralysis.

Cal wrote:In the event of a roll over, your body is fixed upright and can not move sideways, hence your head falls off. Best case, you break your neck.


true - statistically still more likely to clout wall and strike rollbar with helmet than roll over on track. More walls, no gutters.

Not being smart - just making observations based on what i know and what i have seen. In an ideal world the fellow would be all ca$hed up and go out n buy both. He is not, so hopefully he can read all that is here and make an informed decision on what goodies to buy, or what to sell (wife/kids) so that he can afford to buy the goodies - maybe he will even decide to not compete till he has the goodies - he may then decide to go hard on the road like the local P plate/v8/ricer squadrons - that would be more hazardous than being on the track without harness and ROPS. :shock: :shock:

Umm I cut said support away with an angle grinder on the weekend. It is made of fibreglass and would do dick in the event of a rollover.

Cal.

You could also cut through a bed sheet with sciccors. but it can stop a bullet. because its flexible. so is a hard top. Taking a angle grinder to the hard top & comparing it to a roll over is missing the point. The road is flat & blunt. On the road give me a hard top in a roll over anytime thank you very much. Same with the Soft top. from what it looks like. I',m convinced it had a lot to do with saving rodents life or Serious injury at the absolute least. How quickly do you think a angle grinder would get through a soft top.

It all good..... :mrgreen:

I have a roll bar too......harness is on the list.

So you clowns think a piece of fibreglass that is 3mm think is going to save your life when you drop a ton on it, maybe more depending on g forces? You certainly live in a different world to me. Can you fly in this particular universe where normal physics don't apply?

depends on the size and shape of this piece of fibreglass, it could easily support several hundred tonnes if you wanted it to.

I was thinking of something around about this size and shape myself. :roll:

Umm it doesn't state you can use a hardtop with no cage.

The horizontal bars that make up the soft top are probably considered dangerous if you tip it over. So they make you put the roof down. There is nothing there that says the hard top provides any roll over protection -- a good thing, as it would be a lie.

Again, let me reiterate that those bars saved my life :?

You can't know that for certain. Given a repeat episode would you prefer to rely on the soft top bracing or a Brown Davis roll bar?

Heyhey go easy folks. Of course given a repeat episode (touch wood) I'd rely on a BD, or better yet a proper rollbar. However my point was the soft top is better than no top at all should you have neither, at least in my experiences. Make of that what you will.

It's not and I don't use them. I have a complete custom job welded it. The BD is well priced and the best option readily available to bolt in. Do you know of a better option?
