For the benefit of Non-Australians I will explain HSV (one of the decals he was looking for). HSV is Holden Special Vehicles. So Holden create a perfomance car eg. Monaro. Then HSV go and stick a more powerful crate v8 motor from the US into the car. They also do some slight chassis work. Essentially just creating a more focused model.
However probably the equivalent of a ricer culture among many Australians is to get a hold of some old model HSV and mod it up. Although the cars do still have at least a 5L V8 so not really the classic rice. In other ways they are similar for example the decals or lowering the car to a crazy ride height.
But its not that Australians don't have any rice mobiles, we've still got some of them, we aren't really a motoring nirvana.
