Hey guys, I have just bought a set of Tein Super Street Adjusties and still sitting in my garage. Have no time to fit them on yet.

But just afew questions for ya all... from what ive heard, i would need a cert if i go lower then 100mm. Which i dont think i would go over but depends how low the car sits after getting them on.

In saying that....what about warrants? would they fail me bcause i dont have a cert for it even if its not lower the 100mm? Or simply bcause its not factory standard with the car. Advise please!!!

SHODEN

Sorry Shoden, I want to hijack your post for two important suspension matters.

Could people post their experiences in Certification of suspension, and say if you're in Aussie or NZ.

Could you also post who fitted your suspension and what sort of job they did.

A poorly set-up suspension just ruins a car

cheers

Speaking from experience...

YES they will (at least they are supposed to) fail you if you have adjustable platforms in regardless of height. You will therefore need a VVT cert first which will set you back about $350-400 and for them to send for a certificate to wellington.

Get somewhere that knows what their doing to install them because you will save in the long run. Mag and turbo north shore forgot to put a bump stop in in my front right strut and other problems meant that I failed the VVT... iv learnt my lesson

As I understand it, in NZ you can lower a car with new springs, (not cutting the originals) without certifying that car. It will get a WOF if it is not too low (and I assume 100mm off the road is the limit) but I'm not sure how it affects insurance. I think you will have to tell them.

If you use adjustable platforms then you have to get them certified, even if you are using standard springs. This is why ppl are not so keen to go rallying as they used to be, it ia all too complicated and expensive.

Stocks Ltd idea of grooving the Koni shock tube several times to give several optional heights is good, as you can lower the car but it is not adjustable so does not need certifying.

4rolln, tell us what you did.

You guys are right. Here it is from the LTSA website. Full version of the Certification Thresholds here. There is also a copy of the WOF inspection manual here:

"• the springs or shock absorbers are direct replacements, and
• replacement springs fit and maintain contact with un-modified OE seats throughout
full suspension travel, and
• replacement springs are self-retaining in their seats at full extension, without the use
of non-standard devices such as wire-ties, straps, or external spring locators, and
• replacement springs have not been heated or cut, and
• springs and spring seats are not height adjustable (unless OE), and
• replacement shock absorbers fit un-modified OE mountings, and
• suspension maintains sufficient travel for safe operation when fully laden, and
• suspension components maintain sufficient clearance from unmodified bumpstops
when fully laden, and
• a minimum of 100 mm ground clearance exists below any part of the vehicle
structure, or any steering, braking, or suspension component, and
• the normal relationship between front and rear suspension height is not unduly affected"

n.b. the 100mm clearance does not include such items as exhaust pipes and exterior body panels that do not contribute to the structural strength of the
vehicle. I figure that as the Altezza/is has skirting that drops below these parts, you may well be able to appear lower than 100mm but still be within the limits. Looks like you'll have to certify though...

Also from LTSA:

"If your modification or customisation goes beyond the Warrant of Fitness threshold, you will need low volume vehicle certification. This can cost from $350-800. Without getting your vehicle certified it could be unsafe and could be picked up by the police and taken off the road."

Hope this is helpful

I did a bit of research on this topic when I was going to get a set of coilovers.
When you take it in to get it certed, you need to adjust it to the height you want it. They will stamp the height with plus or minus 5mm or so on your plate. That is the height that is certed for and any lower or higher the warrant guys can fail you.

When you take it in to cert, you can drop it lower than 100mm off the ground. As long as the guys there think it's safe, you'll get your cert.

This is what I found out from other forums, correct me if i'm wrong :)

Yeah that sounds right. I think the law is, if you draw a line from a fully inflated tyre on one corner to the edge of the rim on the opposite corner there should be nothing hanging lower than this line. If this is the case and everything seems safe it should be certifiable....again this may be wrong but this is what I was led to believe when I was looking into it. It makes sense as you can run flat without dragging car along the asphalt.

You can imagine how low this would allow with a set of super low profiles on.

i didnt reaise my car was that low, yeserday, i was driving, my cuz was behind me, he said sparks wher coming out as i hit the ground a few times :blink:

Lol! The car is getting lighter all the time!

Who did the Cert for it and what did it cost Shane?

hahaha i know what u mean, when i had my altezza my car used o spark on the rd too, but that was from the exhaust hitting the rd haha

Hey Guys,

Thanx for all your replies and advise. Im might be installing my Adjusties next weekend. When i get the time that is, also have to save for the cert.

Would some places cost cheaper for certs? What will be the best or recommended aligment, toe, chamber, etc...?

What if i was to do a diy on installation? helps....keith? anyone? :lol:


SHODEN

basically take out old and put in new
its easy as since ur not just changing springs

Could people post their experiences in Certification of suspension, and say if you're in Aussie or NZnever got mine certed but current owner has, said it passed no worries, and was done in NZ, i always wondered if it would, shocks started getten a bit noisy over bumps and stuff

Could you also post who fitted your suspension and what sort of job they did.me and my mate did mine in about 1 1/2 to 2 hrs, i found it tightened up the car handling, way better than lowering springs were

So you never got a cert for your one hey Spanky..? Who use to do your warrant? Didnt they fail you for it?

nah still had yearly warrents
so got a warrent and then installed coilovers
still had about 5 mths left on warrent
told the owner so he was aware it wasnt certed and needed one

If they come with the springs on the shocks then changing them is not too bad. We can do it at home.

If they (Tiens) do not have the springs assembled on the shocks then we will need a set of spring compressors to fit them. At that point it might be easier to get Tyremate or Stocks to help.

are they new or used Shoden??

Mark stokes from m.s certifications will cert your justys for $350-400
Im running d2s and loving them

Calvin at Tyre mate will suply and fit a set in your altezza for $1400 or so call (09) 2723288 say your with the altezza club.


In auckland area only :D

Its all assembled... used (2months) brand new.

Wont i need a spring compress to adjust the the height?

SHODEN

I don't think so, there is usually a hook tool to wind the bases up and down.

Lets just get them on and see! PM me for sorting out a day to do it. I'm free most days at the moment as work is slack, just tied up this Sunday with shooting at the Howick Rifle Club.

cheers

basically rip out ur old ones
put new ones in, it is pretty easy :)
u wont need spring compressers

to adjust the height
if u have ones like tein, then u just loosen locking nut and turn the platform up or down to get desired height, or u can turn the spring which in turn turns the platform (foudn that the easiest way)

or if u have ones like d2
just loosen the one locking nut at the bottom and turn the shock and spring

Cool...yeah it came with 2 C spanners.

Ill PM you when and ill have to find a time when im next free. Your at Howick rite?

Also where would any recommend for me to do alignment, camber, etc..? After putting the shocks in

SHODEN

Thanx Spanky.. :)

How much did ya cert cost? Would the prices differ and on what basis? I have called afew places and they are all diffferent prices.

SHODEN

I believe cert costs went up in the last few months - so expect around the $400 mark.

I have had Neil Fraser do the cert on my race car. Hes good, efficient, and certainly knows what hes doing. He can be found at Fraser cars on the shore (beachhaven / birkdale).

well i had my RX323 certed
and it cost $400 for everything that needed to be certed

but if i was you, if u have more things to get certed other than coilovers i would get them done before hand or u will have to pay for another cert :)

"They will stamp the height with plus or minus 5mm or so on your plate. That is the height that is certed for and any lower or higher the warrant guys can fail you."

Are you sure?
I can understand why they would want to establish a minimum height off the ground for safety but why would they be concerned about a car being higher than 5mm above that minimum. That doesn't make sense to me.

Yes that is correct. Both my cert plates have had a +/- 5% with the specified ride height as inspected at time of cert. Unsure of the exact reasoning, but thats definitely the way things are im afraid. Not that i would expect WOF places to measure it though...

Yeah just saw a pick of a transport safety badge + or - 5 % on TM.
http://www.trademe.co.nz/Trade-Me-Motors/C...n-210608209.htm
I guess the best idea would be to get them certified either:
5% above the minimum legal ride height (for super low)
or
5% below the maximum height (if you just want a smooth ride and slightly lower)

So how much adjustability do these shocks normally have?
5%, 10%, 20%, more?

Thats a cert plate, when you install adjustable suspension and get them certified they measure from the centre of the wheel to the top of the guard, the +/- 5% means that when Cops check your ride height the result can vary up to 5% of whats written on the cert plate..

Which theoretically gives you about 15mm adjustability either way (or is it 7.5mm either way -- 15mm total??)

Yeah on that MR2 it would be 15mm either way which gives you a total of 30mm.

Any idea the range in mm of adjustability on an adjustable shock?

It depends, usually the threaded portion is pretty large, on my adjustables the whole bottom of the shock is threaded, I could have it sitting on the ground if I wanted... Its kind of a 'how long is a piece of string' question because it varies so much depending on Manufacturer, Spring Stiffness, Shock Length, Spear Length, etc

Ok so effectively you buy an adjustable shock and then the government limits the amount you can adjust it. wtf is up with that

And dont forget you pay $400 just to have them limit your adjustment
