They will fit well on the front but will be 4mm over track on each side, but chances of a cop pulling you over for 8mm track is near zero, it's not a Nissan so they probably won't even give it a second look

Found this on another site about NSW Transport regulations:

Read it & tell what you think, does it mean that the vehicle would still be legal being 4mm over track on each side?

RTA: Wheels & Tyres

1. wheel track must not be increased by more than 25mm beyond the maximum specified by the vehicle manufacturer for that vehicle.

2. Where non original axle or suspension components are fitted, the offset of the wheel in relation to the axle or stub axle assembly used shall not be increased by more than 12.5mm each side of the vehicle based on the specifications of the axle components used.

Minor Wheel Changes:

3. 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.

4. The outside diameter of the wheel and tyre combination must be no more than 15mm over the largest diameter wheel and tyre combination specified for the vehicle.

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.

Actually, I forgot to take into account that track is measured from the centre of the wheel so a 9 +32 will come out 17mm and also go in 9mm so the centre of the wheel only moves out 8mm, which is within legal limits as it's only a 16mm total track increase, therefore still being legal...

Edit: according to that article ^ your rears will be 38mm wider and illegal

OK, I just got the 18x9.5's +40 for the rear, & they fit with about 5-7+mm clearance all round the suspension components, the tyres better not bulge much though.

Fronts 18x8.5 +35 are in a container on a ship heading this way- ETA 3-4 weeks.

Nice clean wheels with decent dish, only problem is that they do the Coppers work for them because stamped in Big letters facing outward on the rime it says D1 9.5 J x 18.

The Filth will just have to glance at them & know they are too wide.

O' well good thing that I like a degree of dificulity in life...

Edit: I rolled the rear guard lip just a few mill with a $100 (dellivered) Ebay guard roller, easy as.

Here is a little seceret,,, go to Clark rubber & buy a length of solid rubber cord about 8mm thick and once you get a nice bend/roll going,, put the rubber cord in the cavity & you will get a smooth dead level fold L to R. ( it must add some support)

Then when your finished just pull the cord out, it stretches & thins out enought not to be a hasstle to remove

Wait on rims was far too long, but finally rocked up so I chucked them on
Work VS-KF's, long discontinued but bought on yahoo auctions japan

F- 19x8.5+19 with 5mm spacer (so effectively +14) They rocked up with 215/35 but were camber worn and looked far too tiny for a car this size, so after a week replaced with 225/40/19 which fill the guard a lot better

R- 19x9.5-6 Really thought these weren't going to fit, but somehow manages it just. Came with a 235/35/19 but have heaps of tread, will probably step these up to a 40 as well when they die if I can find an appropriate size

Still need to lower the car, the slope is taking a a bit of the rear gap. Going to lower the rear 30-50mm and the front 10-20 to get rid of the jacked up look at the back as tray is usually empty.
