For Questions Regarding WOFs/CERTs/NUMBER PLATEs

[cletus]

I'm not sure if I've asked this before or not, but how legit (or not) is it to machine some material off the hub mating face on the back of a mag wheel to gain a bit more tyre clearance on the wheel arch lip?

 you could if you had a wheel that was thick enough in the hub area, according to the rule book it has to be done by a recognised wheel specialist.

 

most wheels would not have enough thickness if already drilled

Hi guys,

Dereged car with cert - is cert still valid if re vinning and no more mods are done etc

i have read somewhere it should be certified again if rego lapses. cant remember where though

 

however, i know of many cars that have been re reg with the original cert plate as long as the mods match up, i have even organised plates for cars where everything matched but just went from the original serial number to a new 7AT0####### 17 digit vin number when being re reg.

Wheel in question being Cheviot triden.

The face which bolts up to the drum is actually not solid. It's kinda open like those whorey 90's slip on wheel spacers.

hey cletus, what are the goes with quick release boss kits? my ute is kinda difficult to get in and out of with the current setup inside. thought a quick release boss would help, but not much point if they cant be certified/ are illegal

 

 

i think the wording in the hobby car manual says they are not recommended unless its needed to get in and out the car, like if it has a cage.....usually i knock them back cause D1NZ wannabes put them in cefiros for no real reason, plus they are usually cheap china ones

 

So a proper brand quick release in a full cage tech inspected street/strip car is probably ok?

Im pretty certain my mate Clint has one in his caged WRX because its unpossible to get into without a removable wheel or triple jointed knees.

Quick few questions about getting the FX on the road:

 

1) I have done an engine swap from 16v to 20v does it need to be cert'd as its not over 20% more power to the wheels?

2) The Silvertop will run open trumpets with socks on them, it is very loud (induction side, as exhaust is moderate), is there any laws about induction noise over exhaust noise? How do they tell them apart and if there is a limit whats the DB rating?

3) I have put AE111 front brakes on the 82, since they are toyota OEM parts are they ok or should they be certified too?

4) I know the half cage is legal and doesnt need to be cert'd but for easy of police sake would it be better to get it cert'd at the same time?

5) I have been told since it is running adjustables they need to be cert'd, my question about this is if I change the spring rate does that affect the cert, should i wait till i have it setup before going to the cert guy?

6) Is a Apexi-RSM good enough for a speedo or do I need to run a gauge?

7) What are the rules about removing the heater/blower unit and installing a light weight fan unit?

 

Thanks in Advance

Hello Mr cletus.

 

Have been looking at some supplies for lowering my car. Just wanting to know if they would be legit from a cert point of view.

 

For RCA's which version of these two would be easier from a cert point of view?

 

Separate LCA and rack end spacers

 

OR

 

LCA spacers that have a built in steering arm (unsure if this is allowed? They are one piece cast units)

 

 

 

Any obvious issues with these coilovers?

 

 

 

 

And lastly, this wouldnt apply unless I won lotto but how much of an issue would it be to fit these replacement arms?

You will need a cert for the engine, brakes and suspension. When the suspension is certified it's set at that height +/- 5%. I don't think changing the spring rate is an issue as long as the height remains the same.

As for noise, yes it can be too loud but I've yet to hear of anyone getting pinged for excessive intake noise.

It will be running trumpets with socks in a special made box which seals with the bonnet and is vented so it only draws in cold air, worried that it will be far to noisy at the 4,400-8,200rpm mark.

 

Thanks for answering the other questions.

You'll be fine.

I have a 4 inch intake straight from my turbo through a pod filter and it's fine (Makes a hell of a lot more noise than open quads do).

Sweet. Thats a load off my mind.

Would it be legit if a brake conversion sat the caliper so far up, that the top edge of the pad overhung the top of the rotor?

I would have said it looked unlegit, but the guy who's done it reckons it doesn't matter, as the pad will wear, and the overhang will be of no consequence. I have a pic, but I'm not sure how to make it show up here. (I'm a total cabbage at computing)

[Yowzer]

Only thing I can think is if the pads are thick enough that they can touch before wearing right down.

Can a modified car with MotorSport Authority Card and LVV Cert, etc be driven on the road only when driving to/from an event or for inspection/repairs or can it be driven whenever the owner would like to drive it? I've come across both and not sure which to go with. I'm reading up on this as it would give me more flexibility with modifications (suspension mainly, see section 3.1 here, please correct me if I'm reading this wrong) and I would like to enter some events too. While it would not be a daily driver I would like to be able to drive the car on the road as I please. Is that possible or am I just reading this incorrectly??

yep

[cletus]

I am planning on shortening the frame slightly on my KZ440, then welding in a new rear loop very similar to that pictured below. Is this likely to cause issues at WOF time? Are there any requirements or specifications I need to adhere to?

 

 

Cheers

you will need a cert for what you plan on doing, best to chat to a certifier in your area who does bikes so you do it how they want it done.

1. you will need a cert for #3 so your engine mod/swap will be covered at the same time

2. there is no law regarding engine induction noise.

3. brake swap will need cert

4. may as well get that done as well to save yourself hassles

5. ideally you should have it set up correctly before the cert. if you change the springs afterwards and they are still captive etc then nobody would know as the spring rate etc is not listed on the cert plate

6. if its hardwired into the car and not a gps speedo then that is fine

7.i had a quick look in the wof online manual and couldnt find anything that says you have to have a demister

what yowzer said.

it may not happen if the disc is fat enough, but it would still be considered 'untradesmanlike' to do such a thing.

unlegit.

Hello Mr cletus.

For RCA's which version of these two would be easier from a cert point of view?

 

Separate LCA and rack end spacers   these would need TAC approval to use them. might be too much twisting load on the steering arm

 

OR

 

LCA spacers that have a built in steering arm (unsure if this is allowed? They are one piece cast units)probably more likely, i would think these may also need tac approval due to steering force going thru a different path ie thru the bolts instead of  direct to the strut. may need dowels like toyota/datsun strut spacers have. both options would need bumpsteer check

 

just get a s14 silvia man

 

easier

 

 

 

Any obvious issues with these coilovers?whats the spindle/bottom bit made of? if its cast or forged the tube cant be weldeded

 

 

 

 

And lastly, this wouldnt apply unless I won lotto but how much of an issue would it be to fit these replacement arms?

Cheers. Those coilovers are stock tubes with sleeves welded on so should be sweet.

Hmmm. Bit of a noob question but what does tac approval entail?
