They can be road legal if done properly and it depends on the rules in your particular state. By far the best option is to speak with your local registration authority who should put you onto an engineering signatory. The signatory should know all the ins and outs.

In a nutshell in NSW there are rules for head clearance, visibility and access and all bars above shoulder height must be padded.

If you are planning on racing the car, you may also want to check with the relevant authorities to determine what they require because AFAIK a cage that is road legal is not necessarily approved by say CAMS.

My personal opinion (please note this is an OPINION only) for road going cars is that cages are unnecessary but racing is another matter.

Also, if its a bolt in jap cage it is highly unlikely it is approved for racing in Aus either, they need to be either developed or approved locally and jp use a smaller diameter pipe.

Unless you've got a great reason to keep it....out it goes :cool:

Dean, I would love to have one.

SKYL9, I have seen them from around $350 to $750+ second hand - you get what you pay for.

SIR33, just like installing decent sus, installing a roll cage will increase handling. Roll cages increase chassis rigidity which will provide more positive feedback to the driver.

Basically my thoughts are that for a road only car a cage is a bit of a wank, here's my 2c:

Safety benefits are questionable. The RTA doesnt like cages because they pose a striking hazard in the event of a collision type accident which is way more likely than a roll over. Sounds reasonable to me.

Its an expensive way to chase better handling and a functional cage may require some aspects of the car are compromised (eg headlining, rear seat). Compromising the design of the cage to retain car functionality sort of negates the argument that you need a cage in the first place. Also RTA rules can make it difficult to install a proper cage (ie cant have side bars across doors and driver vision/movement not to be impaired).

So the only real reason I can see for the putting a cage in a road car is because you have lots of money and want to look like an uber cool race car driver.

Of course now someone will come on here and say they got an awesome cage for $10 that retains full functionality of everything in the car, increases stiffness by 1000% and its 100% legal :P

$10, are you kidding, my mates mates mates mate got one for $1.50:p

And browny, I have already spent over 30k on my car, and I consider a $500 roll cage quite a cheap mod, but yeah, if you want a daily driver with back seats and all the rest, a roll cage just wont cut it.

Personally, I think it would be worth it, saftey wise, to have a cage in the car. Don't they say driving out on the road is far more dangerous than driving on the race track?? I have seen numerous car fatalities on the news where cars have been stolen, then run through a red light. Who survives?? the thieves....

Sorry, my rant, but if you've ever lost anyone on the road, because of some ignorant *** heads then in my eyes, if you've done everything you can to protect yourself, your better off. NOT just wank factor - a life saver in some cases.....

Did you read why I suggested they may not be great for safety on the roads?

The view by the RTA is that a roll cage is designed to protect the occupants in the event of a roll-over (rare). Because of all the bars and crap that you get with a roll cage it means there is more stuff that you can bust yourself up on in a collision type accident which is vastly more common. Hence in the majority of cases a cage presents more of a safety risk.

Racing is a different situation as there is much greater chance of a roll-over.

THEN add a roll cage, and you are cooking. Besides, I can guarantee that all those pretty DoLuck bits added together probably cost more than 2 roll cages - nevertheless, EVER bit helps, its all good.

for $500, a excellent condition steel cage or an alloy one in decent condition with cosmetic problems. I have seen full chrome molly in near perfect condition second hand for $750.

you're probably right, but you can probably get cheaper if you buy a different brand. Do Luck isn't exactly cheap :)

    • @GTSBoy This method was able to get readings of -10 to -2, so it looks like its monitoring.  Now I need to figure out why the vacuum on the line provided isn't alternating with manifold pressure.  I went with 2 lines that an RB25 tuner recommended but I'll get a longer hose and try directly off the back of the manifold.  He may have been used to OEM intake setups while I have a DBW setup that removed the MAF and IACV.  
    • I work at a car detailing and tinting shop called Quark which gets all manner of German cars in usually (mainly due to a contract with Mercedes Benz Kita Osaka, BMW Nishinomiya and others) but every once in a while something special comes in, like a fully restored 1972 HS30 Nissan Fairlady 240ZG... The shop owner had immediately started applying film to the windows as soon as it was in the shop so the interior was completely covered in towels and plastic sheets. But I could get a few photos of the engine bay which was restored like new. Such an amazing car to see in pristine condition in Japan these days.  
    • Was going to say the car pulls up nicely everywhere, especially going into that last long right hander before the main straight. Looks like a lot of fun.
    • Hey Dave, welcome aboard! Good to see another soon-to-be Stagea owner here. The wagons are awesome — plenty of space, still got that Skyline DNA, and loads of potential if you’re into mods. Definitely post up pics when you get it, everyone here loves seeing new builds. What model/year are you looking at?
