Hi All
I have a Tj magna ralliart 2002 which is lowered. I am currently having trouble with a local highway patrol officer who has defected me again even after i have had the car engineered . He has now got me for vertical ride height . Does anybody know the correct measurements for this . I have been on the RTA website and they don"t have one for the ralliart. I have spoken to Mitsubishi Australia and they dont even have the specs so if anyone could help me out it would be much appreciated
Cheers penang

Thanks here in NSW its 100mm but thats not the problem. Its the distance from the center of your wheel to the bottom of the guard

I would say, being eyebrow height, that it could be similar or the same as a VRX perhaps?
Or maybe just go with the stock Magna height if that works.

Wow man, where abouts is this so I can stay well away from their.. I really thought they canned that rule becuse what about the old commies that had the guard sit over the wheel?
Ps 100mm is 1cm..

Ahahahahahaha that will teach me to post with out sleeping! My bad! Hahahahaha
The rule about wheel arch to centre of wheel was scrapped - that was to prevent people modifying suspension and luckily this affected modders like us PLUS the off-roaders.
So it wasn't just a group of younger citizens with noisy cars complaining, but also some well organised off-roading clubs, businesses, etc.
Tell you MR POPO to go read the rules because the government could not put those ones into effect.
Be nice about it, but also if you feel you're being targeted, complain about harrassment (as long as you aren't doing anything silly to warrant it).
Good luck!
Oggy.

Thanks Oggy but the rule still applies as i have spoken to the RTA . Im doing anything silly to warrant the harrassment this Highway patrol officer just makes it his business to target people with nice cars
I beg to differ as I was part of the movement to shoot down that new rule, including letters to my local MP, newspaper and the joker of a politician who tried to implement the rule.
BUT, I'm not just going to argue, I've gone off to find some evidence.
1) on the RTA website are some vehicle standards information bulletins.
VSI06 is the guideline for light vehicle modifications. It's dated Nov 2007 and I'll try to find if it's been replaced soon, but here's the only text I could find on RTA website about suspension modifications:
Suspension
Besides assuring a comfortable ride, a vehicle’s suspension system controls wheel movement for handling and road
holding. Manufacturers conduct extensive test programs to develop suitable suspension settings. Adjustments, such
as lowering the vehicle, can upset the suspension characteristics and cause unpredictable handling. Generally, roll
stabilizer bars, axle locating rods, upgraded shock absorbers or upgraded springs may be used provided they are
suitable for the vehicle and are properly fitted. However, the following suspension modifications are not acceptable:
�� Welding forged components such as stub axles or control arms.
�� Fitting longer, non-standard shackles to leaf springs.
�� Fitting any additional components or altering the suspension so that the wheels or tyres may contact any
component under the full range of suspension and steering travel.
�� Fitting any additional components or altering the suspension ride height so that any part of the vehicle other
than a wheel or tyre can contact the road in the event of a tyre deflation.
If major changes to the suspension (such as substitution of a non standard front cross member) are carried out, they
should be done under the strict guidance of an engineering signatory.
The proposed vehicle suspension rules were VSI50.
Here's a quote from a 4x4 website on November 2010: at: http://www.aulro.com/afvb/general-chat/114800-nsw-vsi-50-dead.html
Today is a great day for 4WDers, VSI 50 has been scrapped.
The NSW government have deferred VSI 50 to a national board - the Australian Modified Vehicle Certification Working Board.
This means that the State Government have seen the light and have scrapped VSI-50 from their agenda.
The government and Four Wheel Drive NSW & ACT decided to keep 4WDers in the dark regarding discussions about VSI 50. Secret discussions behind our backs is no way to represent 4WDers.
Taken directly from the 4WD Action facebook page.
Whether you love or hate the mag,you can't deny their passion for the industry.I was one of the ones that sent an email,and congratulate every other person that also did likewise,and I also thank 4WD Action for bringing it to public attention,and making the action so easy to carry out.
No affiliation with the mag.Just give credit where I think credit is due.
The rest of the article is on the 4WD Action facebook page.
This VSI 50 BS about very restrictive suspension modification rules was started in July 2009. http://www.news.com.au/approval-from-rta-needed-to-raise-or-lower-car-suspension/story-0-1225750899656
I thought it was destroyed after approx 4 months but I didn't realise it went for a revision and there was actually a version 2 announced in 2010, but luckily it seems to be off the books now.
If you can find any evidence that vehicle height has to be kept within 2" of standard, I'd love to hear it.
But as far as I know and can find out, the only standards are: at least 100mm clearance from the lowest part of the car (that isn't a wheel/tyre), something like 600(*)mm from the ground to the centre of the headlight and about 400(*)mm to the indicators and of course the rules above about the wheels and tyres not coming into contact with any parts they shouldn't.
( *: I'm not sure if 600 and 400mm are the right numbers for those measurements, so please don't take my word on that part, hence the "something like" and "about" prefix :) but there are rules on that if you need to look them up )
Hope this helps you. I think you're the victim of ignorant police and RTA staff - ask for something in writing next time you speak to them. Go visit the RTA and police station, explain how you've been defected and you want to know what the rules are, in writing. I think RTA also have a technical department that you can email - that's what I'd search for, being lazy as I am. If you do talk to them, a quick solution might be to ask them if this is to comply with VSI 50 - the one that was withdrawn for review before it was ever implemented.
Cheers!

Well i spoke to the RTA tech department and they told me that the vertical ride height is still in use . I have put the standard springs back in as i cant take the constant stress from this Highway Patrol officer . Once again thanks Oggy for tracking the information for me
Someone was saying at the autobarn meet in SA that since it is fron the centre of the wheel to the lip of the guard, make sure they measure to the guard and not to the plastic flare that sits on the edge.

The measurement is taken from the plastic flare per the manufacture specs
