i think youll find that any aftermarket part(suspension wise) which introduces the ability to "adjust" that was not there before will need cert

ie tie rod ends - already asjustable so new one wont need cert,
adjustable camber arms, old ones wernt adjustable, new ones are = need cert

thx for the info...
anywhere i can find the info as the reference for assignment???

there is none. ive rang up the LTSA and LVVTA and neither could give me a straight answer about weather u need to cert them.

technically speeking as luke said they are adjustable and should be certed, but within the adjustment range of them is it really going to upset the handling that much? if anything ur just going to end up with more negative camber

i had mine in the car when i went for a couple of onroad WOF's and they didnt say anything about them.

Interesting point, I think the law is more aimed at adjustable height rather than camber adjustment isn't it? Not being mechanics up there that seems to be their main bogey.

the laws aimed at safe handling of the car, how do u expect them to measure the angle of ur wheels and note down the deg of camber u have? if they dont do this then isnt it pointless them certing the adjustable part on ur car? if u can adjust it to what ever u want it to be?

but i feel this will be interesting when i doing the assignment...in some how...i always feel that adjustable camber kit is more danger than the coilover....the incorrect way to install or incorrect screw us in the kit, or poor quality of the kit will lead to the whole suspension going apart....but it have clear statement said that coilover need cert but nothing in those kit?

Just pointing out it's a grey area, there's plenty of lowered cars with decent negative camber but the main attitude is well, they're your tyres that's gonna wear. You're more likely to get stickered for height than excessive camber.

Camber in itself isn't necessarily a safety factor as such, negative can actually help as you know. If there's no specific about it they obviously don't seem to care, I'm suggesting it might come into alignment adjustment rather than performance adjustment, not saying it's right as a badly made component is still dicey.

and theres also the fact is you can be low and not have a camber kit aswell. as most people who install the camber kits do so for a few reasons. increase the life of there tires or to increase handling of there cars.

youll also probably find that most companys who make camber kits have to meet the US DOT regulations or something simular

My car failed it's WOF with adjustable camber arms and I had to get it certed. It's flown through the 3 WOF's I've had since then. As b16a2 mentioned, if it wasn't adjustable from factory, it'll need a cert.

Really, your supposed to cert any modification you do to your car.

[Horny_Devil]

hmmmm to me its a grey area, as in the LVVTA document (http://www.lvvta.org.nz/stdSuspensionSystems.pdf) there is nothing mentioning adjustable suspension compents except for lowering the car.

and the only passage of the VIRM (WOF manual: Vehicle inspection requirement manual - In service certification - WoF only) that is even closely related to this is this passage:

A modification affects a component or system that directly or indirectly affects the directional control ofthe vehicle, and:
a) is not excluded from the requirements for LVV specialist certification (Table 9-1-1), and
b) is missing proof of LVV specialist certification, ie:
i. the vehicle is not fi tted with a valid LVVcertification plate, or
ii. the operator is not able to produce a valid modification declaration or authority card.

so the LTSA is saying u need a LVVTA Cert but the LVVTA has no criteria in which to cert you by

thats how i interperate the documents

I was told from a local certifier that anything aftermarket and adjustable in regards to steering and suspension needs to be certified. had this problem going for a wof at local on road station with adjustable front camber arms. they weren't too sure if they were adjustable and told me if the cert guy says they dont need certing then they will give me the big tick, unfortunately, the cert guy wasn't in my favour

i just got an aa vehicle testing station warrent with adjustable front camber arms and they didnt even say a thing
