Thread: D2 Internal or Exo Roll Cage

exo = illegal unless you call it a ladder rack. There is a mob in the UK that make bolt on ones for em cant remember the name atm.

Internal is someone with some sense and a pipe bender should be no real illegallities with it that i am aware of as you see plenty of rice rockets around with em. How hardcore are you going with your car cages is starting to get full on. If your planning on rolling your car id take it out there on a trailer!

Without have actually checked the regs, I think there are some issues with internals that relate to head clearance etc.

Rules for internal are stricter than external really and depend on the state. It will need to be engineered. Some states (Qld) for example allow more than others.

Thanks for the info.

I will check the regs if I can even find anything there and I will check with the engineer approving the other mods.

I found the Safety Devices internal cage for the D2 but I am not paying $5,000 plus for a roll cage.

I should be able to get access to the tools required to bend and weld my own.

The mods on the disco have ended up going further than initially planned, it is going to end up more comp truck than daily driver.

I have been thinking a dual cab D2 on a 130 chassis would be a good daily driver and tourer.

It can be done having a internal rollcage registered and engineered. I have gone through this with my 80 series. I have a six point cage fully engineered and legally registered and noted on my rego papers. I am in NSW.

It is clearance that is the issue and you cage will need to be padded. You will need to comply withLight vehicle code of practise 3.6 occupant seating and protection. You will also need a engineer that is prepared to accept that it can be done. Most will tell you that a 6 point cage can't be legally engineered. The interior space on an 80 may be roomier than a Disco? Don't be afraid to question them and politly show them the documentation if it can be done and comply. My engineer initially refused to acknowledge the cage and I questioned him as I had sent him a lot of information regarding it. He provided me with the speciafication and I did the rest. The cage complied.

Make the tool out of carboard and and string and do the measurmentds before spending thousands on a cage. That's my advice. You will quickly find out if it can be done or not. If you are in the Western Sydney area I still have tool if you wish to take some measurments. PM me.

Cheers, Chris

Further to Chris's comments I have a fully engineered internal/external 6 point cage in Qld.

One of the first steps I would take is to find an approved engineer who is happy to talk through it with you

Is this for hard core competition?
If it is for competition you will likely have to comply with the CAMS regulations (unless your club operates outside of CAMS guidelines)as well as the local Roads and Traffic regulations.
Many serious, approved competition cages will not pass roadworthy without specialist rego applying.
I am going through this at the moment with another non LR vehicle.
A serious 6 point or better approved cage for competition will cost you around the 5k mark as quoted. Weigh this against the likelihood of injury to yourself for the level of risk and apply that to you being off work recovering. (or not)

Without engineering advice or approval, you are wasting your time and shouldnt expect to pass any roadworthy. If you build it yourself make sure you use the right materials, mount it correctly and be serious about what you need the cage for in the first place.

Expect some big variations and probable exclusion for your insurance from most general companies.

cheers

IF you are intending on comping this thing then id suggest just de-registering it and going ballistic. Most internal cages make a mess of your dash which could be an issue with the dual SRS. As strangy said you need to weigh up what sort of stuff you are going to be driving with it and divide that by the likely hood of you being injured. If your wanting to get serious about competition maybe keep the disco where it is and get a RRC.
