The Epa Thread/Roadworthy Thread

Short answer was also based on little sleep in a foreign country.

The difficulty is the component you want to modify is considered a suspension component. Suspension components generally are not allowed to be modified at all. This includes welding/bending/cutting/ etc.

The reason for this is the impact/shock loading on the component will require analysis and the OEM have already completed this and strengthened this area up if it was prone to failure. By you cutting and welding in a new section, you are changing the specification and strength and in turn affecting the performance under load. This will make it prone to failure.

VASS Engineers will ask for receipts if you fit aftermarket components, so they can shift blame to the component manufacturer when you kill yourself and your parents are trying to sue the engineer. That's kind of loosely what they do, but they also have to calculate the component strength if it is modified. This takes time and requires many calculations/analysis and therefore you pay for this with an engineers certificate...

Thanks for the reply guys

as i called around i picked up some info and basically got the go ahead from at least one guy saying that i wont even need an engineers for it and if needed he will pass it easily or a new bracket made up from RHS as i happened to ask that too

you cant modify suspension components at all ( cut n weld ) but as the castor rod mount is just a bracket that bolts up i've been told that i can .

wht510,

you seem to have decent info, do you work around auto engineers or such. no chance you've mistaken the bracket for a suspension component as i'm told its fine as its just a bracket ?

Yes, you are right. Again refer back to previous post..,. Little sleep and foreign country makes it difficult to think!

If you were going to modify the castor rod, then no, if you were going to modify the bracket it bolts on to, then you may be OK. Depends on your mad fabrication skillz and whether or not you actually do a good job. Again, what R31Nismo administrator dude suggested is correct, speak to your engineer before you do it and get his/her/it's approval, and you should be laughing.

RWC, if you may it look factory, they wont even notice...

Interesting experience with a defect notice recently..

Cleared it before the suspension of rego deadline, then got a letter a couple of days later (still before deadline) saying I had not complied with the notice and so they would be suspending my rego.

Called vicroads and the lady on the phone said they issued the letter as I had not cleared the defect within the one week deadline (after which time you cannot drive the car). I told her that this did not constitute non-compliance as I did not drive the car after that time, and cleared the defect prior to the suspension of rego deadline. She did not seem to understand this.

Does this make sense to anyone else? They have issued instructions and then purported to penalise me for complying with them

[Dan_J]

its usually specified time limit + month there after before its de-rego'd unless its gotten tighter

try legal aid or another branch of vic roads

hey guys, not sure if anyone has mentioned the hole people make below the washer bottle for the fmic pipe yet. any views on that one?

Don't really know what you want to know about it. you haven't made that clear. It's illegal if you have airbags I believe because it's a monocoque chassis and it changes the crumple zone and how that affects the airbag deployment. If you are thinking about cutting a hole, don't. If you have the hole already, get a return flow inter-cooler setup and weld that hole shut. If you get caught it needs engineering among other expensive things.

[scotty nm35]

No need for cutting holes these days, there are many return flow options out there. I have been doing custom piping for many of the Melbourne guys, s14/15, 32-34's and c34 stagea if you have a local fabricator they should be able to whip up something legal like this... Keep the stock airbox and you are good to go.

[xALmoN]

looks great!

[jukic.j]

Yeah looks good I want!

It's been mentioned, many times.

It's illegal in any car that came with an AIRBAG.

[headwithbeard]

ok, thanks a lot guys.

just moved from nsw and unfamiliar with local rules, bought one with the hole cut without even thinking about it and kicking myself for doing so.

[mahum]

hey. trying to get a RWC at the moment. all easy stuff they have picked up except for one thing im not sure of

when you turn the high beams on the low beams turn off. is that normal? if not any idea what the issue is?

[Odium]

when you turn the high beams on the low beams turn off. is that normal? if not any idea what the issue is?

My R33 turns off the low beams when you've put on the high beams,,, I thought this was normal?

Are you saying that your car is keeping both high beams on and low beams on at the same time?

[mahum]

It does not keep them both on. one or the other. mechanic seems to think they should both be on.

however everywhere i read is saying that there should only be one or the other on (with R33s)

[Dan_J]

your rwc guy is wrong as its that way they came. theres a mod to make them both say on though

[mahum]

Cool. I'll let him know. Thanks

[Dan_J]

is there much of an issue with little caliper to rim clearance yet no rubbing?

Edited November 7, 2013 by Dan_J

[wht510]

Yes.

The OEM design has factored in the clearance from the calliper to the wheel under "normal" operating conditions.

So for example the following events occur all at the same time:

1. Wheel bearing is lose but still drivable and still to specifications.

2. Flex of the calliper is at maximum due to temperature and the driver pushing hard on the brake pedal under an emergency stop.

3. Cornering force as the driver does a maximum "G" corner acting on the stub axle/wheel/bearings/strut or knuckle etc.

4. Hitting a small pot hole while doing all of the above.

So I would find other cars with factory clearance of your particular car and replicate that. Otherwise you need to consult an VASS approve Engineer and ask them.

I can't remember the minimum clearance, but from memory it's approx 5mm from the face of the caliper, and the edge is similar. If the wheel moves more than that, then you are stuffed anyway and the clearance from the calliper to wheel isn't going to make any difference!

[Dan_J]

thanks, will sort out some other rims for rwc as theres less then 5mm clearance
