I've just recently been pulled up and had my car gone over and I've got a couple questions so if anyone has some first hand experience or knows the actual rulings then please post.

-What mod plate (if any) is needed for an aftermarket fitment of an intercooler? The car in questions is a KE70 corolla. No chopping of the body was done to fit it, but the front lip/apron was removed and appropriate mounts made up.

-What are the rules on the WIDTH of wheels? I was told that my wheels were slightly sticking out of my guards and I was planning on just flaring them a bit to cover but wasn't sure if that would be enough.

I've always been under the impression that you're able to go 2" more than standard..?

Any help would be greatly appreciated smile.gif

what state?

in qld i think it just has to not have any holes cut anywhere or any reo cut either

if you can fit it without modifying reo or places like under the guards that its ok i believe

but if its gonna be engineered check with the ppl who will be doing it

i got pulled up a couple of weeks ago by the qld police and got defected for my intercooler piping because there was a hole cut in the inner guard for it to be installed.

i contacted the department of transport and asked them about getting a mod plate done for the intercooler and they said that there is no such mod plate for the fitment of an intercooler, but i went to a local mechanic who does mod plates and he put the code down as installation of an aftermarket turbo and pipework (intercooler piping).

when i got pulled over the cops also checked my rims as i have 19s on my skyline and they were all legal and good. they just have to be the same overall diameter of the stock size wheel that the car came out with.

I'm in QLD and two 3" holes have been cut to get the piping through. I might make a few calls tommorow and see what answers I get.

Thanks for the info mate, just what I was after smile.gif
Although with the wheels, I'm more worried about the width regulations rather than diameter.

I'm thinking that if I flare the arches a bit more than I shouldn't really have any problems. The wheels in question are 15x8, standard KE70 wheels are about 13x5.5/6 I think?

Sigh, wrong.

You can go 15mm larger or 26mm smaller rolling diameter for your wheels.
2" is just a rule of thumb, as staying within the correctly specified load and speed ratings of the tyres will generally only allow for a 2" larger rim. This isn't always the case however.

You can only increase track width by 26mm.
Track width is measured from the centre of the tyre to the centre of the opposite tyre. So you can only have 13mm more poke on either side if retaining the same width wheels. Wider wheels will also play a part in how much overall poke you'll have.

The tyres can legally only go 1.3 times wider the largest factory size.
So if it came with 165's the largest legal size you can fit is 215's. A loophole you could probably get away with is slightly stretched tyres. Providing they are the correct speed/load ratings and don't look like they're about to fail from over stretching.

The Wheels must not protrude the bodywork when in a straight position.
Pretty self explanatory. Flares count as bodywork too.

And the wheels mustn't foul on suspension or bodywork.
Tested by a fully laden vehicle with the wheels turned full lock. Test person weight is 68kg +15kg luggage per person where space is available.
