welded in cage front, bolt in rear cage etc etc etc.

Why not just weld the whole thing in??

cos i want to have back seats. pull back seats out and bolt in cage for track use.

I'd check with your engineer, as that sounds highly illegal.... :lmao:

really?

 

I'm not too sure on rollcages. I thought as long as it didn't obstruct the drivers vision or movement and it was padded it was sweet. so if the bars aren't even in the back there are just mounts how could that be illegal?

 

I'm not sure :lmao:

no, you're not, and we are

call an engineer

can someone explain to me how it would be illegal? It would be just like a half cage with a few extra mounts welded onto the bars.

Because as per the Qld Transport regulations for an LH8 mod plate (either that or it's LK1, I can never remember...) for the cage to meet specs it must have the rear legs in.

 

Basically, if you Mod Plate the cage, the car must be driven around with the cage design that it was plated for, otherwise you are deviating from the design, and your cage is illegal. Having the front half of the cage in also borders on dangerous, as the triangualation that the rear legs provide will not be there. ie: don't have an accident. Not to mention insurance for having an illegal mod.

 

 

In short, I very much doubt you could pull out the rear legs, and still be legal.

so if you were to get a half cage you would only be allowed to get a rear half cage is that correct?

 

is it possible to have a full cage while still being able to have passengers in the back or no chance?

 

thanks

1) Correct. Rollcage design is all about stregth. Triangulation aids in strength. Front half of a cage is a box: limited strength.

 

2) Doubtful, but as Jamie said, talk to an engineer.

 

Edit: having said that, if it's going into a 70, then no chance, after thinking of where it would have to mount. Talk to above said engineer. They have the final say.

ok thanks.

 

would having a full bolt in cage but only having the entire thing in when on the track be legal?

 

or am i clutching at straws

are bolt in cages still legal???

 

if so what happens if you unbolt the cage and drive around without it in the car? wouldn't that make the car illegal, because it's been plated for a cage???

 

f@$k it, just weld a whole cage in there and tell the passenagers to walk or buy there own f@$ken car.

no what I mean was get a cage made up but because it would never even be in there on the streets *at all* then you wouldn't need a plate for it.

last engineer i spoke to about a cage said as long as there was "sufficient head room and padding", i could keep the back seat in

 

that being said, such a "cage" would just be a rollover bar and two legs that follow the roofline back to the parcel shelf or seatbelt mounting points, and would be of limited real use, so i didn't bother

 

basically, the idea is this - if you're getting that serious about your car that you fell you need a triangulated rollcage, you're also getting that serious about racing it that the car is becoming a purpose built machine, not a useful and adaptable daily driver, and you can choose one passenger/navigator to ride in the other racing seat, not cruise around with 5 mates in the back anymore

you would probably have to register it as a two seater with a complianced cage.

 

sounds like you need two cars, a normal street car and a dedicated club car.

if so what happens if you unbolt the cage and drive around without it in the car? wouldn't that make the car illegal, because it's been plated for a cage???

yes, you're driving the car around in a specification that differs from the engineering cert

f@$k it, just weld a whole cage in there and tell the passenagers to walk or buy there own f@$ken car

agreed :lmao:
