Wheels - What is legal?

That's irrelevant in a thread about legality, because neither of those options are even close to legal.

I bought my first WRX in 1994 and enjoyed a few years of worry free motoring before they became popular with the exact demographic this car is being marketed at (the Silvia demographic).

These cars will be cop magnets ... and probably rightly so.

I'm putting 18x7.5 by +45 with 225/40 federal 595 rs-r on mine easy, legal, and won't upset the handling balance.

If you feel it isn’t relevant, why did you mention it originally?? Seems counter productive.

With regards to legalities of the track, I guess it’s lucky it isn’t your car, huh?

This is what I'm looking at too.

The Toyota supplied TRD wheels are 18 x 7.5 with 225/40 Michelen Pilot Super Sport tyres on them so I'm comfortable that it'll be legal and handling will be ok. Problem is the TRD wheels are about four times the price of after market wheels so definitely won't be using the actual TRD wheels.

And, as the TRD version here doesn't have the TRD coilovers (they are an extra) I assume all with fit on the stock setup.

Might look at 18 x 8 but only if will work and handle with stock setup without long-term issues. Don;t know much about wheels so will need to research or get advice on that.

If you want to be *REALLY* picky like some on here, technically that isn’t legal either. That will increase your track by 28.15mm, which is 2.15mm over legal :P
I am assuming, that like me, you don’t care too much about a slight track increase though

Either Work Emotion CR-Kai 18x7.5 or Enkei PF01 come in the rights sizes and offsets. Weight is the enemy with this stuff. Both of those options are quite good weight wise vs. OE

I know you have a bee in your bonnet because I didn't want to listen to your dealership cheer-leading, but you have once again made a statement that is completely incorrect and misleading.

Panman, your example only increases track by 6mm and is perfectly legal.

Track increase is to the centre of the tyre - because I'm going at the +45 or at worst +48 offset (same as std) so increase in track will be around 6mm.

I don’t have a bee in my bonnet about anything, mate. I just get annoyed when people post retarded shit, act like fuckwits, think they are better than everyone and point fingers where there is no need to. If you want to bring up the alleged “dealership cheer leading” or whatever the fuck you want to call it, I suggest you actually read the whole thread, then get back to me. I did no such thing, and made ONE post about ONE good experience... hardly what you’re accusing me of... If a number of people are bagging out a place, how is it “cheer leading” if one person makes one comment about a good experience?
I don’t know what you’re fuckin problem is with me though?? I couldn’t care less if you listen to me or not Don’t flatter yourself.

I am not sure where you got your track calculation from, but I typed in all of the information into a track calculator and it worked it out. It says there is a track increase of 1.126in. Do they maths. 1in = close enough to 25mm. Now all you do next is multiply 25 x 1.126, and let me know the result

What do you mean I have “once again made a statement that is completely incorrect and misleading”?? That’s a rude implication there, and you are guilty of providing incorrect/misleading info as well mate...

I know what track is and where it is measured from
Here is the detailed calculator I sued

Take a tablet and lie down, then go see your doctor and ask him to remove that bee.

I see you're happy to dish out shit/accusations, but never seem to back them up.

I rechecked the placard on the wheels (which I have here with me Work Emotion CR-Kai happy to post photo of placard if requested.) 18x7.5 +48.

According to the calculator you used it's actually 22mm increase in track which either way is legal (I went in and entered the details).

I apologise if it seemed I was taking sides - an error on my part.

At this point I bow out of the conversation between yourself and coyote.

I worked it out with the 17x17.5 +45 you gave above, Yes the +48 will decrease the track difference.
Didn't think you were taking sides man, just linking to the calculator I had used

Got it - wanted to make sure I corrected my mistake so everyone was on the same page. I didn't want to add fuel to the discussion

To summarise, according to the calculator with:

18x7.5 +48 and 225/40 18" = 22mm increase in track width.

With documented proof.... (Placard attached).

Sweet, too easy dude

Can you two stop measuring your twats, thread is for helping others about legalities.

Hey, I simply corrected an error ... then bowed out when someone went on a rant. The error needed correcting, as it's important.

I'll state again, for the purpose of testing legality in Qld, a +45 offset will result in a 6mm increase in track, which is legal.

Of course there'll be a small increase in the scrub radius, but that won't have the kind of detrimental effects that offsets of +30 or less may be prone to.

Is this calculator correct?
If I put in the same details for both wheels it shows track diff as 0 which it should.
Then if I change one tyre by 10mm (so 215 to 225) it says the track changes by 0.39 of an inch.
That sounds wrong to me. The tyres simply get wider but the centre of the tyre doesn't move at all.
Or do I not get it?

I think you are correct, and the calculator makes the same "assumption" I originally did - Outside of Tyre vs. Centre of Tyre so overall "Track" changes, but not by the definition the QLD government uses which is where the centre of the tyre is in relation to the centre of the car.

Either way the electrons on the interwebz are providing lots of argument fodder and I'm legal.

[Z86]

Yeah its pretty crazy - the way I see it is going from +48 to +38 is moving the centre of the wheel out by 10mm on each wheel - so total track change is 20mm - regardless of the width of the wheel.
