Ok. My A31 cefiro has a full cage which i know is illegal and cannot be engineered.

However, ive heard that half cages can be engineered.

I have also heard in 2 door coupes to engineer a half cage, the back seats need to be removed along with the rear seat belts.

If this is true. How does this work with a 4 door like my A31?

Can someone shed some light on this situation for me please?

You can't have a cage in a location where an occupant can possibly strike their head.

Your options are to get a removable cage, and only fit it for off-street events, or delete the seating positions where the cage is permanently installed.

You can easily get half cages Engineered/Rego'd in your state. You just work in the guidelines set out.

Simply talk to the relevant transport authority, or better yet, talk to a cage fabricator. They generally are the best people to talk too.

If the cage business says they do not know, go to one that does. A decent workshop that takes interest will know and be upto date with the laws.

I do believe you can get a half cage legal and retain rear seats.

I think you are NSW, so the Vic info i have won't help you.

The same basic rules apply for all states though - the cage mustn't be within a certain distance of the occupants (I can't remember the exact distance any more) and must be padded. I'm yet to see a decent cage design that allows anyone to keep the rear seats, so work on the theory that your car will become a two seater.

Yeah im pretty certain in QLD for registration cages have to be bolted in only and not welded. I'm looking into this for next year aswell as i want a registrable half cage that is cams approved.

what is the story on bolt in full cages? as in with the front hoops that go around dash?

Full cages are a no-no, unless your car is on race/rally rego and you enjoy wearing a helmet everywhere lol

emagine the looks from other drivers. :( so full bolt in can be legal if its plated / run as a half cage?

wrong. depends on the state.

it is legal in victoria as long as you follow of the restrictions of how close the cage comes into the passenger zones.

edit, such cages would have to go through the dash, cages going around the dash(not only do they suck) but they wouldn't pass.

I recently got a new car and it has a full 6 point cage.

It is engineered and registered. I can get the details of the engineers report if anyone is interested.

I have also seen at my old work a 9 point cage in a GT3 porsche that was also engineered with removable side intrusion bars with very similar wording in it.

not true if my memory is correct when i spoke to brown davis he said only half cages are legal, and that he wrote the RWC conditions on roll cages so seems to know his stuff

having said this my memory may be wrong.

    • Did this end up working? Did you take some pictures?
    • And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!
    • And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.
    • Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).
    • You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before
