Hi Guys,

Went to price some 20x8.5" wheels for the ZR6. Bob Jane T dorks said that they can't legally put them on because the Aurion std is 7" and you can only go 1" over ( 8" ). I notice that a heap of you guys are riding 8.5, so...whats the deal ?. As I understand it, As long as the wheel sits inside the Guard it's OK ! The Aurion has a heap of room it seems to accomodate even 9" IMO.

Your thoughts and experience is appreciated.

PS - I'm in NSW, so maybe rules differ from state to state.

I'[ll be out all day to day, so can't respond to any replies till late this avo, thanks in advance.

cheers,

Sounds about right. You might need an engineers cert for them.

p.s. please don't buy wheels from Bob Jane, get a real brand.

So the dozens of different wheels they have on display are only for decoration?

Yeah they do have a dozen different types of wheels on display, but have you ever seen four of the same wheels on display, hence they only sell tyres!

Anyway back to the original post. The Bob-Jane guy is half correct. You can not go over the 1 inch extra on the width, but it is on the largest optional wheel available from the vehicle manufacturer. In this case would be the 18" by 7.5", so the maximum you could go is 8.5", without going over the restrictions.

Taken from the RTA:

Wheels up to 26mm wider than the largest optional wheel recommended by the vehicle manufacturer for the

vehicle can be fitted without the need to notify the RTA.

Front wheel drive vehicles:

Except where the original manufacturer provides to the contrary, front wheel widths shall be no more than 26mm

greater than the widest optional wheel offered by the vehicle manufacturer. This requirement also applies to fourwheel

drive vehicles with constant front wheel drive.

Also you will need to keep in mind not to increase the track width, as there is a limit on that too.

Ref: Guidelines for alternative wheels and tyres

Note: the TRD's run 19" by 8" with 245/35R19

HAHA. I didn't realise you were being sarcastic. No I like stupid........ more stupid.

Do they seriously sell air? or are you being sarcastic again?

Yeah they sell Nitrogen to inflate tyres. Although 78% of normal air has nitrogen in it. Which just means that your tyres are more likely to hold their pressure levels.

legal schmegal... go 20" x 12"... :lol:

seriously though, does anyone know the law on "the largest optional wheel recommended by the vehicle manufacturer for the vehicle"?

like, the ZR6 and the TRD are theoretically the "same" vehicle. (ie an Aurion)

so from my understanding, you could legally put a 9" rim on the ZR6 because its 1" bigger than the std rim on the TRD...

Hmm...

Ash made a valid point. For a state in Australia (I think Brissy), the easiest way to calculate a legal upgrade in diameter of a rim is 2" of the stock rim. This doesnt justify the exact reason why ATX (16" stock) could only wear 18" while the Sportivos, Prodigy and Presara (17" stock) could upgrade up to 19" with all of them having pretty much the same spec in terms of handling and safety.

This means Aurion couldn't wear 20s in the first place, let alone 8.5" width with only 1/2 inch difference. If you're concern with 8.5" width, you should also consider to downgrade ur options to the 19" range.

For our case, Thanks to the TRD backin us up. :D

I would think the same as well, however I'm not 100% sure how the TRD falls within the Aurion lineup. It may actually be classified as a different model to your normal Aurion hence the wheels scenario doesn't apply.

But seriously though, I haven't personally heard of defects for having a wheel that is slightly larger than allowable.

Would have liked to get 20's but from what I can tell you've got $2k for the wheels (make sure the tyres are the right load rating too as apparently there aren't that many 20in out there with the right load rating) then to make them look right you'll need lowering and to lower effectively without the suspension bottoming out on bumps you'll need to spend at least $1500 to get coilovers so you're really up for at least $3500 and I couldn't justify that.

      1999 Camry Driver's door locking hatch issue

      It's possible that it could be something fouling or dirt build up, dry, or a broken mechanism, so have a look and give the mechanism some lubrication, most likely though, it'll be the actuator. I found one for a good price on Ebay, $25 delivered: Front Door Lock Actuator Right Side For Toyota Camry 1997-2001 | eBay

      Query about the correct rotors for 2006 ACV40 Camry.

      Hi, I'm looking at a set of front rotors for an ACV40 2006, 2.4L Camry. I got a good price on some RDA's at Sparesbox. However both RDA8112 and RDA7686 show as for my car and I'm wondering what the difference is and if there were changes to the rotors during the model production. So does anyone know which rotor is the correct one? Many thanks in advance.

      It's a simple solution though? Already laying down 60k for a RAV4, so what's another 1k on a phone to make everything work seamlessly? 👍

      Your solution is akin to suggesting that switching to a different car manufacturer would resolve the issue. However, not everyone shares the same enthusiasm for using an iPhone as you do.

      Turboed Corolla Overbuilt?

      that engine will be fine, the rods are the main thing to be concerned about. The 2860 is a decent turbo for the 1zz but in this day and age I'd go for a G25-550. The injectors might be on the small side, we run DW1000's. You need a full length injector, the shorter injectors with adaptors like ID1050x dont fit the 1zz head. You don't need an aftermarket intake manifold, if you do go down that path, avoid the CNC innovations unit, it's garbage. Do the boost control with a MAC valve and control it with the aftermarket ECU of your choice, I use Link stuff on most of my builds with the G4x Storm as the minimum. I also wire a fuel pressure sensor and oil pressure sensor to the ECU in my installs. Use a decent intercooler, the better cores (ARE, PWR, Garrett, Vibrant, Plazmaman, Hypertune) work a lot better than the chinese stuff like Aeroflow. a 450x250-300 fits fairly well with custom end tanks to route the cooler pipes through next to the radiator Don't forget about the clutch and gearbox. These days I like the Uniclutch twinplate, Above 300whp you'll want to think about upgrading the 3rd and 4th gears in the box also with the SSC (Hollinger) gear set and install an LSD of your choice. If you're going to give it a hard time, you'll also want an oil cooler. I like the HKS thermostat type sandwich plates and setrab or mocal oil coolers with -10 speedflow fittings/lines (Chinese AN fittings neck down to a lot smaller internal diameter in their bends, not great for flow) You'll also want to think about brakes, Celica or Sportivo front calipers will bolt on with sportivo discs as a starting point. To have somewhere like Tunehouse do the work you'll want to budget somewhere between 20-40K

      Camry Touring 2010 Fuel consumption 15.2L/100km. Normal?

      I did the mathematics myself regarding costs vs benefits for fuel injector cleaner. I have changed from 91ULP to 95PULP and 98PULP. Price difference can be about 13 -20 cents. Compared to 91ULP, Premium quality fuel should have a better quality additive package designed to have superior engine cleaning capabilities so the engine can perform at their best.

      "Fuel injector cleaner is a waste of money" Only if you by the cheap crap if you use LiquMolly a German Product it does work and you won't waste your Money.
