@ Hansen - Jump onto nissansilvia.com, that's probably going to be your best bet for over on the East Coast if you're looking for stuff like shells etc. Unfortunately cars in Aus hold their value for a lot longer than cars in the UK (or so it seems) so you'll have to look for a little while to see what you can find.
@alanford - Exact opposite, the reason this car had to be like this was because it got a yellow sticker (the sticker you can see in the top right of the windsheidl). If a cop can find 3 things wrong with your car (and this is super subjective, I once got one because my seatbelts might be frayed, battery wasn't using stock clamp and having a didlo shift knob, on my 2000 R34) then you have to go to the pits where they check the car over, and if anything else is wrong they add it to the list, so you have to keep going back until it's all perfect again, then off you go, and the next day if a cop looks at you and doesn't like the way you look back you can get another one and start all over again =P

I know it needs more slammage too, when I put the rims on I wasn't sure how far it was going to go down so I wound the coilovers down to a surprise height and put it on the ground, unfortunately it was way too high haha. Rears can fit half of one finger between rim and guard but fronts are terrible.
