General Modification Guidelines for NSW

[bennjamin]

hi all. With car ownership comes the need to modify and what not...make it original...your own :)

But there are rules. STRICT rules....lets keep a nice little guide up , for people to come back to and see the latest rules etc.

For starters ,

Here is the latest car modification guideline for RTA .

http://www.rta.nsw.gov.au/registration/downloads/vsi/vsi06.pdf


Relevant to NSW.

Also , relevant in NSW for engine conversions ~

A car can replace its engine with the same layout (IE 4cyl for 4cyl)
to a engine same age or NEWER , and also within +15% capacity increase.
You need to take your car to a AUVIS , to change the engine number over.
You will then take the documentation to the RTA and change engine number over:)

This will NOT attract a blueslip. You will only need to
change the engine number over at the RTA :)

Actually you need to get it certified by an AUVIS though, and then take the 'change of details' blue slip to the RTA. Cost is around $40. Had to do that a couple of years ago when I had a motor replaced with a second hand one.

[bennjamin]

to be exact , AUVIS yes :)

NSW Rims and Tires Information:


ADR 24 CEASED TO HAVE EFFECT: 1 January 2005.

Re: Accuracy of Speedometer & Legal Rim/Tire Combinations
http://www.rta.nsw.gov.au/registration/downloads/vsi/vsi09_rev4.pdf

Up until July 2006 the Australian Design Rules required new cars to have speedos that are accurate to within 10% of actual speed when traving over 40km/h. The current Rules disallow under-reading, and permit over-reading by up to 4kmh + 10%

Wheel/Tyre Combinations:
When selecting your combination, you must take into account your stock recommended rim/tyre combination from Honda/Car Manufacturer.

This information can usually be found on a Placard found on the inside of the Driver Side Cabin Door.

In NSW you may only have an increase of less than 10mm of your TOTAL DIAMETER. That is, the length around your wheel + tyre.


Example: (Ru$ki's Original Post (http://www.ozhonda.com/forum/showpost.php?p=1026043&postcount=46))

For the purpose of an example, a vehicles' stock wheel and tire combination is 185/60/14

Said vehicle can legally use 205/35/17
- The rolling diameter is decreased by 0.3mm

Because: the speedometer is 0.4% faster and as a result, if the Speedometer is reading 60km/h your actual speed is 59.42 km/h.

This vehicle cannot legally use 205/40/17:
- rolling diameter increased by 18.2mm

Because: the speedometer is 3.2% slower and as a result, if the Speedometer is reading 60km/h your actual speed is 61.92 km/h

Wheel / Tyre Combination Calculators
These tools will help you calculate what diameter your wheels and tyres are or will be, and also tell you how much difference there is on your speedometer.

NSW Window Tinting:
http://www.rta.nsw.gov.au/registration/downloads/vsi/vsi03_rev3.pdf

Front Windscreen:
You may ONLY have a band at the top, provided it is no more than 10% of the height of the front winscreen, and is not in an area swept by the Wipers.

If Vehicle was registered on or after August 1, 1994:
35% Visible Light Transmission (VLT) Minimum on rear, and sides.

If first registered before August 1, 1994:
35% Visible Light Transmission (VLT) Minimum, unless darker already fitted.

NO Metallic Tinting. AT ALL.

[Bayani]

NSW Ride Height
http://www.rta.nsw.gov.au/registration/downloads/vsi/vsi05.pdf

As many car enthusiests do for both styling and performance reasons, Lowering your Vehicle is one of the more common options. However, some are not sure what is legal and what is not.

In NSW the lowest point of your vehicle may only be
1. At least 100mm from the ground within 1 metre of any axle.
2. At least 1/13th of the distance between the centers of adjacent axles at the midpoint between them, and
3. at any other point - the distance that allows the vehicle or combination to pass over a peak in the road, the gradient on either side of which is 1:15, when the wheels of one axle of the vehicle is on one side of the slope on one side of the peak, and the wheels of the next axle are on the slope on the other side.

This includes Chassis, Bodykit, and the Exhaust System.

However, this is not the only thing that is checked. Some vehicles, even when lowered to the legal ride-height can still be defected on the grounds of their Headlights.

Headlights? Yes. That's right. Headlights must sit a minimum of 600mm from the ground.

NSW Tachmeter Installs

Installing a Tachometer into your car can prove difficult when you are trying to place it.

Gauges outside the car, on the Bonnet, commonly seen in Autoshows are not legal.

Gauges on the A-Pillar are not legal.

[Bayani]

NSW Pod Filters & Noise Control

Pod Filters

Air filters that are not enclosed are deemed a fire hazard and are therefore in 99% of cases not allowed.

In the context of Noise:Section 20, NSW Protection of the Environment Operations (Noise Control) Regulation 2000
A person must not cause or permit a motor vehicle’s engine, or its air intake or exhaust system, to be modified or repaired in such a manner that the maximum noise level of the motor vehicle after the repair or modification (regardless of the noise level of the motor vehicle before the repair or modification) exceeds the maximum noise level specified in Schedule 1 for that kind of motor vehicle.

For those who missed it. Pods' are legal, so long as they are enclosed. Not just Covered. ENCLOSED. The enclosure is a noise reduction device; removing it may result in a fine from the RTA, a Defect, and may result in cancellation of regisitraton.

Noise Control Devices must not allow noise emissions that are higher than the OEM devices.


Noise Control:
Exhaust noise from vehicles should not exceed the prescribed exhaust noise levels. These are given in Schedule 1 of the Regulation. Levels are established from a set testing procedure also described in the Regulation.

Schedule 1, NSW Protection of the Environment Operations (Noise Control) Regulation 2000 States:
Before 1 January 1983: 96 dB
On or after 1 January 1983: 90 dB

Testing proceedures:
http://www.legislation.nsw.gov.au/fragview/inforce/subordleg+537+2000+sch.2+0+N
The Department of Environment and Conservation (DEC) is currently considering how the implementation of the new Australian Design Rule 83/00, introducing new vehicle noise limits for vehicles manufactured on or after 1 January 2005, will affect NSW noise legislation.

Vehicle owners and operators should ensure that their vehicles are not fitted with defective mufflers.
Section 18, NSW Protection of the Environment Operations (Noise Control) Regulation 2000 States:
1) A person must not cause or permit a motor vehicle to be used on a road or road related area if the motor vehicle’s noise control equipment:
(a) is not securely in place, or
(b) is defective.
Maximum penalty: 100 penalty units in the case of a corporation, 50 penalty units in the case of an individual.

(2) A person must not:
(a) remove, or render less effective, a motor vehicle’s noise control equipment, otherwise than for the purpose of repairing or replacing it, or
(b) replace a motor vehicle’s noise control equipment with noise control equipment that is less effective than the original noise control equipment fitted by the vehicle manufacturer.
Maximum penalty: 100 penalty units in the case of a corporation, 50 penalty units in the case of an individual.
(3) For the purposes of subclause (1) (b), defective noise control equipment includes:
(a) equipment that allows the emission of more noise than the original noise control equipment fitted by the vehicle manufacturer, or
(b) equipment that has, in the opinion of an authorised officer, been modified in a way that makes it less effective than it would have been if not for the modification, or
(c) equipment that allows gas to escape from a place other than the intended exhaust outlet, or
(d) if the equipment concerned comprises a system of mufflers—the system contains fewer mufflers than the original system fitted by the vehicle manufacturer.

[kid_dynamite]

Just a suggestion. It would be fantastic if ppl who post can support these with guidelines / legislation, especially the roadworthiness related ones (eg the pod filter / suspension height)...

NSW, Before you Modify!

This is a very useful document that generally explains what processes you may need to go through for some modifications

http://www.rta.nsw.gov.au/registration/downloads/vsi/vsi06.pdf

When carrying out Modifications you may be required to contact a Engineering Signatory. A list of Signatories can be found here:
http://www.rta.nsw.gov.au/registration/downloads/vsi/vsi15.pdf

ADR's are Federal Requirements, State Requirements superceed ADRs and should be followed.

Ignorance is not a valid plea in court.

[Bayani]

Carbon Fibre Bonnets / Trunks / Panels

Are they legal? This answer is not as simple as Yes and No.

These are the conditions:

A Carbon Fibre Panel (being a Hood, Trunk or Fender) may be only fitted if it is ADR Approved, OR it if there is an Engineering Signatory that has signed off on said panel attached to your vehicle as being within the rules of the relevant safety guides.

The issues lay with the following:
Hinges : The area connecting to the Hinges to the Bonnet / Trunk must be sturdy & safe.
Latches : The latch / catch system used to prevent the bonnet / trunk opening. (Well know systems include the Bonnet Pin System)

To ensure your Carbon Fibre Panel is complaint, look for ADR approved Caborn Fibre Hoods. Do NOT buy cheap imitations. Whilst they are tempting as cheap alternatives to the real-deal, they are a CONSIDERABLE risk to both your safety, and the safety of others.

This was RTA Confirmed.
There is no legislation proclaiming that CF panels are illegal, but they MUST conform to particular standards.

Here is the latest car modification guideline for RTA .


latest? it is April 2005.

this is all covered in this thread anyways:

PLEASE NOTE THE REFERENCES TO THE NEW:


National Code of Practice for Light Vehicle Construction and Modification (NCOP)

The National Code of Practice for Light Vehicle Construction and Modification (NCOP) has been prepared by members of the Australian Motor Vehicle Certification Board Working Party in consultation with industry, user groups, government agencies and individuals with an interest in light vehicle construction and modification.

it has/will superceed the RTA stuff...

[tinkerbell]

i have just confirmed with RTA Tech Line (1300137302)

that it is up to the individual engineering signatory on whether they adopt the NCOP or the current RTA adopted regs (VSI06 is a short guide) in certifying a cars compliance...

Yes, they are allowed, but the screen may not be visable by the driver in the normal driving position.

Vehicle Standard (Australian Design Rule 42/00 – General Safety Requirements) 2006

42.16. TELEVISION AND VISUAL DISPLAY UNITS
42.16.1.General

All television receivers or visual display units and their associated equipment must be securely mounted in a position which:

42.16.1.1. does not obscure the driver’s vision;

42.16.1.2. does not impede driver or passenger movement in the vehicle; and

42.16.1.3. is unlikely to increase the risk of occupant injury.

42.16.2.Restriction on Visibility of Screen

Unless a driver’s aid, all television receivers or visual display units must be installed so that no part of the image on the screen is visible to the driver from the normal driving position.


ALSO:
http://www.legislation.nsw.gov.au/fragview/inforce/subordleg+341+1998+sch.4+0+N

42 Television receivers and visual display units

(1) A television receiver or visual display unit must not be installed in a vehicle so any part of the image on the screen is visible to the driver from the normal driving position.
(2) However, subclause (1) does not apply to:
(a) a television receiver or visual display unit that cannot be operated when the vehicle is moving, or
(b) a driver’s aid in any vehicle or a destination sign in a bus.

Examples of driver’s aids:

1 Closed-circuit television security cameras.
2 Dispatch systems.
3 Navigational or intelligent highway and vehicle system equipment.
4 Rear view screens.
5 Ticket-issuing machines.
6 Vehicle monitoring devices.
(3) A television receiver, or visual display unit, and its associated equipment in a vehicle must be securely mounted in a position that:
(a) does not obscure the driver’s view of the road, and
(b) does not impede the movement of a person in the vehicle.

What about seam welding a car and using it for daily use?
i couldnt find any info on that...

[Bayani]

Explain... :]

[Limbo]

No the structural integrity will be compromised, there were some half cars welded together a while back it was on the news. They were being sold and later the owners found out they were defective.

[Bayani]

I would assume, now.. I ASSUME that there would be a Signatory required for that.


Note to Self: (These posts of mine will be removed & replaced with more useful information in the future).

[kid_dynamite]

Bayani it's important to note the difference between federal (ADR) and state regs.

The ADR requirements are the minimum roadworthiness/safety requirements nationwide, but states may enforce higher standards if they wish to.

[AUSVTEC]

By saying seam welding i dont mean piecing two good ends of smashed cars together, thats just dodgy unless done right...

I mean removing the seam glue from all joins on the car and welding the seam together with 1 inch intervals all over the car. (like race cars)...
Dose this need need to be engineered so you can drive the car on public roads.

[bennjamin]

the chassis is reinforced and will act differently in a crash ( IE wont crumble as easily but probably bounce off the impact and away) so it will have to be engineered

[AUSVTEC]

Cool, i thought i might have to pay another visit to my engineer to have it checked and noted on my eng. certificate

thanks bennjamin

[Bayani]

.. That's what he's saying. LOL

The car effectively becomes a metal enclosed ball. It' won't crumple like a car with a weaker structure where windows are.

That and, in the event of an accident, you'll be trapped inside a metal sack. Bit of a problem if the car's fuel is leaking, or there are fumes.

[Bayani]

Ok, everyone that's posted in here, replace your post with something useful :P



Same Goes for the Spamming Thread. LOL

[aaronng]

A crash in a reinforced chassis at high speed will give you more internal injuries from the higher G forces during deceleration.

Carbon Fibre Panels

[kid_dynamite]

Below is the list which is used by Authorised Inspection Stations to reject number plate mountings. Keep these in mind.

Note that no mention is made about side mounted plates. However like anything the police could defect you, and you'd have to prove to the RTA it's legal (i.e. by following the belowmentioned points).

- Any part of the number plate is more than 1300mm from the ground;
- The number plates are not substantially parallel to the vehicle’s axles;
- Any number plate is obscured, for example by a towing attachment, gooseneck or tow ball;
- Any number plate cover is tinted, reflective, rounded or bubble like;
- Any number plate is not of RTA issue, is damaged or faded to the extent that the registration number is not visible;
- Characters on the number plate are not clearly visible from a distance of 20 metres at any point within an arc of 45 degrees from the surface of the number plate above or to either side of the vehicle.

[simonnowis]

does this mean its illegal to do a conversion on a eg hatch breeze which has 1.3L to a k24 2.4L?

[bennjamin]

It means it will have to be entirely engineered to whatever spec...$$$$$$$$$
You can increase +15% of the stock engine capacity , without getting "engineered" . Just a change of engine number and you are fine.

Hi people very cool stuff, just wondering about Lighting like Neons and stuff.
Im in NSW if its state thingo. Cheers people!

[kazam]

any sort of neon lighting is a defect... but if u have a switch for the inside ones, u can easily switch em on and off, coz u cant reallly see interior neons from the outside, but exterior neons, your buggered

[kingkongw24]

ok yea but like your number plate lights like its blue is that legal ?? and like HID legal or not and what colour and stuff, is there no government official paper that says it all?

[kazam]

no my number plate light isnt legal and i think HID's are illegal to!

^^^now with all that said... who here thinks they'll pass.... this test is absolute bullshit... if my now stock del sol can't pass this then no Holden/Ford can.. stupid department.

My results today was 86dB and 92dB on throttlr off coz of the stupid buzzing of the oem Honda muffler

[tinkerbell]

i passed by an RTA approved engineer in an '83 prelude with a JDM B16A runing a 2in exhaust and a straight through Genie Turbo muffler with 2.5in tip...

i got between 88.7 and 89.1dB readings...

i doubt the tests are different,

we did the test in a car park next to a large cricket oval, so there were no walls around at all...

[dsp26]

^^^ i rex i would have got the same as you... except mine was in the shop driveway with walls to both sides.. but it was pretty wide... still i'm sure echo has an effect.

i did manage to get mine down to 84dB on/off throttle consistently... anyone wanna know can PM me.

Wasn't using a apexi ecv was it?

Anyone else used one?
Supposed to reduce db my about 10 in the closed position.
Best not to draw attention in the first place where excessive noise is not acceptable......ie...around police cars....lol

Should have mine in about a week so I'll let u know.........

[tinkerbell]

except mine was in the shop driveway with walls to both sides..

therefore an illegal/non-conforming test.

[dsp26]

therefore an illegal/non-conforming test.

I will bring it up with the DECC... it was quite difficult to pass.

only mod on the car when it did 90dB/92dB was 4-1 extractors and a 2.5in mandrel catback going into a standard muffler.

though i'm sure they should be aware of it as they even take pics of the testing location.... might drive-by one day and take pics myself.... what's your say on this matter tinkerbell? worth the effort taking it further?

nope. turns out it ain't road legal... the only variant of it thats legal is the Remus Powersound muffler which is manually adjustable with varying butterfly sizes as well... only one of the three in the range is EPA approved (the one with the biggest butterfly)... but thats when the EPA was around... the DECC are stingy.

[tinkerbell]

though i'm sure they should be aware of it as they even take pics of the testing location.... might drive-by one day and take pics myself.... what's your say on this matter tinkerbell? worth the effort taking it further?

i posted a link in the other thread:

open the .PDF and check out Section 3

i would assume this still applies.

Damn it, how did you find that!

I had to phone the EPA to get that info.

The Apexi ECV has a full size butterfly valve and is manually adjustable....so wouldn't that make it legal according to your criteria?

...although I realize it is illegal to perform testing with it in the closed position.

The point I was making was that if you don't draw attention to yourself/car then you won't be required to do the inspection...hopefully.....:thumbsup:

it is quite possibly in breach of the Road Rules (particularry if the police officer is having a bad day):

http://www.legislation.nsw.gov.au/fragview/inforce/subordleg+179+2008+pt.18-div.1-rule.297+0+N?tocnav=y


297 Driver to have proper control of a vehicle etc

(1) A driver must not drive a vehicle unless the driver has proper control of the vehicle.


(1A) A driver must not drive a vehicle if a person or an animal is in the driver’s lap.


(2) A driver must not drive a motor vehicle unless the driver has a clear view of the road, and traffic, ahead, behind and to each side of the driver.

Carbon Fibre Bonnets / Trunks / Panels

Are they legal? This answer is not as simple as Yes and No.

These are the conditions:

A Carbon Fibre Panel (being a Hood, Trunk or Fender) may be only fitted if it is ADR Approved, OR it if there is an Engineering Signatory that has signed off on said panel attached to your vehicle as being within the rules of the relevant safety guides.

The issues lay with the following:
Hinges : The area connecting to the Hinges to the Bonnet / Trunk must be sturdy & safe.
Latches : The latch / catch system used to prevent the bonnet / trunk opening. (Well know systems include the Bonnet Pin System)

To ensure your Carbon Fibre Panel is complaint, look for ADR approved Caborn Fibre Hoods. Do NOT buy cheap imitations. Whilst they are tempting as cheap alternatives to the real-deal, they are a CONSIDERABLE risk to both your safety, and the safety of others.

This was RTA Confirmed.
There is no legislation proclaiming that CF panels are illegal, but they MUST conform to particular standards.

Regarding this... I have just been through my cars engineering. I have learnt the following:

* Carbon Fibre bonnets are legal

* Whilst talking to every single engineer on the NSW list, most of them have said they are legal, and the purpose of a bonnet is to cover the engine so people can't put their hands inside and burn themselves, or get their hands in the belts. Apprently it is a rumour that crumple zones etc are taken into consideration. It's a fact that CF bonnets don't crumple on impact.
However, some engineers say that these bonnets need to be ADR approved, or crash tested to get them engineered.

* Bonnet pins are legal, as long as they don't stick up tooooo high. "Jags and mercs have those stupid badges that stick up, why can't you have bonnet pins" - quote from 2 engineers I spoke with.

* However, in order to comply, there has to be a hook and latch type system like OEM bonnets. Bonnet pins are simply not enough.

Roll Cages

Also...

* It is legal to have a HALF roll cage, that does NOT go past the B-pillar. However, it needs to be engineered.

* Only with NO rear seats, and NO rear seat belts. Having passengers in the rear of car with a roll cage is highly illegal!

* It can be bolt in, or weld in. Doesn't matter.

* Main hoop has to wrapped in foam or some sort of padding greater or equal to 8mm thick (Apparently, according to Engineers)

* Car has to be registered with the RTA as a 2 seater once engineered.

Do you have to get things like a new header k20/k24 hybrid engineered?

[tinkerbell]

yes. it is emissions related.

[Punisha00]

I have one question if its legal in one state and i move to another state and change rego over does it still mean its going to be legal or do i have to remodify to make it legal? and if its not and i dont change my rego over and get pulled over do i still come under my state rego law or the states law im in?
oh in regards to the CF panels my engineer told me it comes under fibreglass section in body mods link: http://www.infrastructure.gov.au/roads/vehicle_regulation/bulletin/pdf/NCOP6_Section_LH_Body_Modifications_3Feb2006.pdf

[Zedski]

Has anyone had any experience with WA laws and Mod Guidelines? More specifically with whether permits are legally required for CAI w/ pod, exhaust (full kit) and full body kit. The Dept. of transport website for WA is pretty vaigue and has a lot of links to pages and pages of crap which is still over complicated and vaigue.
