For Questions Regarding WOFs/CERTs/NUMBER PLATEs

[oldrx]

Planning on cutting the bump stop mounts off and plating over as coilovers have their own stops and need clearance, thoughts?

[cletus]

That would be fine, but

Whenever changing bump stop position or length,  you need to make sure that there are no things like arms fouling the body, tyres hitting the body,  or joints binding because the suspension is operating in a different range of travel than the original design 

 

Bump stop type, location, and setup is one thing that is very common to get wrong, a lot of people don't understand what the bump stop does and how important it is

My FC Rx7.

Certed years ago for Tein coilovers and front strut brace.

I have brandnew BC Gold 4 corners as recommended on here by OS, so future WOF be no issue I assuming.

 

Further, fitting non factory turbo, FMIC, braiided engine bay lines etc so it WILL need a new cert or as engine still 13BT it 'not' modified? 

[cletus]

Will need cert.

[Bling]

Certs would be a great if you could change every part of the car and it was still ok, lol.

Asking for a friend, how would you get on certing a 356 coupe replica? 

Same as the roadster/vw based bathtub?

 

[RXFORD]

I'm assuming its glass and on a shortened beetle pan?

Who made the body?

 

If its glass and on a beetle pan I would think it would be treated no differently than a vw beach buggy so it would end up as a 'scratchbuilt replica'

But if its on a 356 pan it could be a different story. 

[63Ragtop]

Yes, fibreglass on a shortened vw floorpan.

This place is in the UK, I'm sure there are others.

I don't think the real ones ever had pans.

Just occurred to me that you see plenty of convertibles and speedsters, which for some reason don't appeal to me.

[cletus]

Would be do able for sure

How difficult it would be is a how long is a piece of string question

 

The main thing would be making sure the body has appropriate framing in it for seat belts, door hinges, door framing, torsional rigidity, etc. If it doesn't have this then adding it can be difficult depending on how the body is made

Right o lads. 
 

I’ve been chatting with a couple of guys about this topic and keen to know the answer to report back. 
 

is it legal here to “flip ball joints” ..

relocate the ball joint above the lower arm using a spacer on top of the arm and a spacer to fill the void the ball joint took up.

Obviously using higher grade bolts.

 

im sure I’ve seen this posted somewhere but search results net zero.

 

thanks in advance

Hello, 

I want to add in some strengthening to the Mokes lower firewall/steering rack area. Either with a plate like this from Urchfab in the UK

It looks like this 

 and looks like this when welded in 

Or try make something similar up myself. 

Obviously I'm going to run it past my repair certifier. But has anyone tried to do anything similar to this before and it been fine? Would go a long way to strengthening the part where the bottom of the front subframe bolts up and the steering rack area, which is a common weak point and I have hear of cars cracking in this area due to fatigue. 

[ul9601]

Do less than 35% VLT pass WOF, if OE fitment? There are heaps, I think most of them being Japanese import have way darker than 35% VLT.

How strict are the WOF outfits when it comes to tint and gigantic stickers and such? I got pinged for supposedly 13% tint (came with the car) and I think that was about right.

OEM is fine from memory and yeah as you say usually just imports and rear windows, the rest will be up to inspector but are fails usually. For stickers it depends where and how far they extend from the edge of the window. Also depends on vehicle class and all sorts of rules. Plenty of info for tint / overlays / stickers in the online VIRM documents. "came with the car" isn't going to trump any rules.

cant see a problem with that, would need lvv cert as its a modification, rather than a repair

assuming you are talking about a ute or van where the ball joint is under the arm and the shock or bump stop is on the bottom arm 

 

probably ok if the bolts are big enough and that part of the arm is strong enough to handle bump loads, as they will be holding up the vehicle instead of just holding the joint against the bottom of the arm

 

and theres no other problems like upper ball joint bind or mental camber because the suspension then has heaps more travel in bump

20 odd years back, a friend blacked out his mid 80s turbo 323. (The first of the front tug ones)

A cop pulled him up pretty close to home, and advised him that it was illegal/go home and scrape them off right now and I wont sticker your car.

He also gave him a copy of the glazing rule/virm etc. (Whatever it was called in those days)

He removed the tints, and studied what he'd been given. Then re-tinted it to the absolute letter. 

He interperpreted it where it says "stickers" within 100mm of the edges, and laid the absolute blackest tint known to man right around all the windows. (With the legal tint in the remainder of the windows) 

I was like bruh, you're gonna get stickered ow fulla bei!  He was sure it was fine.

Then one night out at the skids/diesels (as was the fashion at the time) he was accosted by a different policeman. Who said "scrape em off, or I'll sticker you!"

My mate attempted to show him the literature the other cop had given him. But he refused to even read it.

So he complained to the police complaints authority (as they were known then) and,

The NZ police (taxpayer) had to pay for a shop to retint his car like it had been! 

(The shop made a nice job than he had too)

My names Bart  and that's my story.

yup im aware of that section of virm, actualli i asked vtnz about some (i thought to be) contradiction in ther but apparently i was wrong.

but anyway, just wondered how these cars get away with ~5% vlt tints (i had 5% glare strip), big stickers with some sort of "car club logo" or filipina thing or RIP whatever someone s name is, usually south auckland cars.

was tossing up going NA but apparently extra 40 bux rego for up to 0% vlt rear side and back.

WOF fails, as mentioned. People run around with wires sticking out of their tyres, doesn't mean they have found a loophole on tyre requirements.

No idea what car you have, but how do you plan to turn it into a light goods vehicle?

nzta put me in touch with vtnz branch which can inspect and change class - they said a couple hundy for fees (i think) and just fold the seats down and have it fixed (so that it wont be able to be reverted for seating readily , i.e. without tools) i think they said i wont even need to remove seat belts.

its a wagon. i "may" need the cargo divider, but not sure.

[Bling]

Fair enough then.
