Good morning,

qurstion you probably get asked 100000 times a day,

what’s the budget one should allow for cost for coilovers and wheels on a Japanese vechile?

also for getting multiple wheel options is there a  further cost per wheel?

thank.

retail price is $580 for a basic cert inspection, plus hoist hire at a workshop if necessary

extra set of wheels- there isn't a set price for that, stuff like that I base on how long it takes and how helpful the owner is.

Ie if theres another set of wheels in the boot and I have to swap them over myself, then it would cost more, than if the owner swaps them while im doing the paperwork

Thanks for that. So my reading of that is that you can have a switched 'bimodal' exhaust as long as it is not manually actuated and as long as it doesn't exceed the max decibel limits under either mode? 

I have had this question before and the answer is yes you can have a bi-modal exhaust, but one side has to be quiet, and the other side has to be more quiet.  ie: you cannot have quiet and loud modes.

So effectively exactly what you and Cletus have said.

Great, will look to go that way then I think, a boost referenced valve that is as loud (flowey) as legally poss when open, and quiet as possible when closed

How would a WOF etc test this? Not like they can run it up on a dyno, get it on boost and then volume test it. Its a good idea, im just curious myself.

Or more likely, would they just require you to have it in the "open" setting during testing, and fail you if you cant/dont?

The decibel test is done with the engine not 'loaded'  ie in neutral, take it up to the test rpm, start the meter reading, then let it drop back to idle

So I've got my spacer to put the rod end at the right height. I've got my "beefy washer" at the bottom to prevent pull through. I've got a Grade 8.8 bolt and the shank goes all the way through all the bits(the extra spacer at the top allows me to tighten the nut).

But that beefy washer and bolt head are now REALLY close to the wheel. I had to space the wheel out with some 3mm washers. So now I have 3mm clearance.  

How much clearance is enough clearance? 

I can space the wheels out further...

Question regarding steering setups for my 720/Safari mashup.

I have the NZCCM, and it has this section:

image.png.a0a350c7cedaa7a1c0b3c9baec69081e.png

Essentially my question is: The pair of UJs (1 either side of the intermediate shaft) would be supported at the firewall, and the steering box. Is that what it's asking for, or some sort of inline bearing on the intermediate shaft?

Probably an obvious answer but I wasn't sure. 

If the answer is a support on the intermediate shaft, then do I need to incorporate some degree of movement (i.e. rubber mounting) as it is a cab on frame and there will be a degree of flex? Or is that negligible and it can just be hard mounted?

 Thanks in advance.

If a vehicle come with lspv as per pic. Can I remove it when certing for other mods?

i.e longer rear break line for lift and remove it all together

yep as long as the brake bias is ok, ie lock it in the right position, or fit an adjustable bias valve

if you just have 2x ujoints, you wont need another support, the steering column (if its got a bush/bearing in the bottom) will support one, steering box will support the other

 

if the body is rubber mounted you will need some sort of flex in the system to allow for body movement on the chassis- either a rubber rag joint, or ujoints and a sliding shaft

On a macpherson strut type suspenion - is there a minimum amount of thread that needs to extend past the end of a nut on the two bolts securing the shock to the hub(knuckle/carrier)?

EDIT: 'Two threads clear'

correct, 2 threads past the nut

I've read conflicting information, is it acceptable to modify/shorten/weld half shafts? 

EDIT: Looking into it, I don't think welding is an option but shortening and resplining could work.

what application?
