The only thing you have to worry about, apart from the tyres sticking out of the guards is rolling diameter.... you can go +15mm or

-26mm

Pages 10 and 11 has the info.

and to calculate u can use..

I might be totally wrong and probably am lol but i didnt think you were allowed to increase overall track by more than an inch. Don't even know if the GTR rims will do that, but might be worth looking into...

I was thinking of doing the same thing to my GTT so would be keen to know if it is ligit!

PS drift barbie - I have an aftermarket ecu, what were u wanting to know? and yes i know u werent asking me :P

The problem you'll have is that they do protrude ever so slightly from the front guards.

lowering, camber + skinnier tyres will fix that :)

But yes as someone mentioned above, as long as OD is not more than 15mm and wheels/tyres do not sit past the guards you are fine. This is for QLD.

You will however find a large majority of hardcore wannabe drifters think of you as a softc*&k for asking the question though because to them if its not hella flush (wheels stickin 50m outside the guards) you are an epic fail.

I've seen plenty of 34GTTs run 34GTR wheels....legal or not legal depends on the mood of the day. I would class it as very mildly illegal.

yeah pretty sure you can't go wider than 30mm from the standard tyre,

bingo...

You can increase the diameter of the rim as far as you want as long as its no bigger than the original OEM delievered diameter including the tyre...

The statement below is true also when refering to the above line... This is the max varience allowed when changing the profile of the tyre to suit...

you can go +15mm or

-26mm

col, i think he may have been meaning the width of the tyre, rather than the diameter. the widest you can go is 1.3 times the widest option stock tyre that was available on that car. so even if the car came with a widest optional tyre of 225 you could still run 285 tyres (1.3 x 225 comes out at 293 so you could probably get away with 295s)

the other thing you have to take into account is that changing in your track. you can increase the track by up to 26mm, but can't reduce it at all. so that means that gtr wheels won't actually be legal because they have a lower offset. and before people start saying that they came on the same generation car, the gtr runs different track to the gt-t. the front is the same but the rear is different (it's wider), so putting the gtr wheels on will reduce the track. however if the gtr is listed on the same tyre placard (sticker just inside the door) as the gt-t then you could get away with it.

Sorta, I didnt explain myself very clear... But in short you can run 17" rims on a car that came out with 14's if you want...

As long as the overall diameter of the tyre is no bigger than the OEM product...

As there is slight difference always the DOT came up with a suitable legal variance...

you can go +15mm or -26mm

I stated 30mm, meaning an R34 GTT can run up to 255 without being much of a problem in terms of sticking out etc...

That said however it depends on the size of the rim as the profile size will change the first number factor...

As for width yes there are some loop holes as to running even wider rubber, however there are other factors that usually stop you from doing so...

You cant run rubber wider than you guards, if it sticks out its illegal (hence offset of rims is so important)...

Also I should point out the rubber sticking out is really down to the kindness of the officer as to whats right and whats wrong. Ive heard of a VE GTS (stock rubber) being booked by police in QLD for having rims and tyres that are aparently illegal by DOT standards. These were factory fitting rims and tyres, so even if legal cops can still put you through the hoops if they want...

The legal line is quite clear in here as posted the other week...

    • Just trying to get my head around this. At 5psi of boost, you turn on your wmi pump, and then you're using a 3000cc injector, to allow flow upto the actual engine, where you have your 6x200cc injectors and a 500cc injector. If the above is correct, what advantage are you obtaining by having the 3000cc injector blocking flow, is this just incase a line breaks between that injector and the motor you can stop flow immediately? Or are the 6x200cc and 500cc less injectors and just spray nozzle?
    • Welcome! New member myself, but I had an R33 back in 2002. Best advice I could give, based on my experience: if you're running the factory turbo, be very conservative with boost. I made the mistake of just fiddling around with the boost controller and cranking the boost for fun, and the end result was my intake pipes popping off frequently from the constant deluge of oil that was being blown into the recirc by the stressed-out turbo, which itself was siphoning oil from the engine and farting it out both sides of its centre bearing (or something to that effect). If I could do it all again, I would have gotten a new turbo and had a tune dialled in professionally and then just left it alone! Funny you mention the metal shavings in the gearbox, as I had the same thing - the probe plug (magnetic drain plug, essentially) would come out caked with shavings. At least it was doing its job. Not sure if that's just sacrificial wear and part of the deal, or if my gearbox was shagged, but I wasn't abusing it. Enjoy the R33 - they're a dying breed, and if they weren't $35k+ on CarSales in Queensland, I might have picked up one of those again, instead of the 370GT I own now (though I'm loving the 370GT, that big 3.7L V6 just hits different).
    • Howdy folks. I owned an R33 back in 2002, which was thoroughly beyond my capacity (financially speaking) to maintain/insure, so we parted ways in 2004. Fast forward 21 years (to literally yesterday, in fact) and I'm now the proud owner of a 2007 V36 370GT. I'm happily surprised by how much power the VQ37VHR makes, compared to the RB25DET, considering the latter is turbocharged. I had planned to add a turbo at some point but I'm on the fence about whether I'll even need it (though I do love the sudden onset of extra torque). Any other 370GT owners around the traps, I'd love to hear about your experiences with this car (good and bad).
    • Perhaps the answer is... more jacks!* *proper jacks must be used.  
    • I NEVER think about using a scissor jack unless there is absolutely no other alternative. f**king things are dangerous, annoying and stupid.
