They don't stretch the rules much for imports. All grey imports have to be substantially modified before being registered in Australia. This can include new seat belts, added side intrusion bars, new wheels & tyres, altered rear view and side mirrors and windscreen glass. Cars that have been heavily modified in Japan need to be returned to stock before being registered. That's why they're still expensive (relative to NZ, for instance).
Car manufacturers can have certain aspects "deemed to comply" with ADRs by undertaking extensive testing. This sort of thing costs car makers and importers of foreign new cars a lot of money, because Australian rules are very tough. We often don't get certain versions of cars in Oz becuase it would be too expensive to comply them.
There's definitely no problem with anything fitted to a factory Commodore - the guys at Holden would know the rule book inside out, and they wouldn't be permitted to release a car without passing all ADR's first.
What I said was correct. Cars imported from Japan must comply with the following guidelines regarding tint and windows:
• Japanese Industrial Standard JIS R 3211-1979 Safety Glasses for Road Vehicles
Cars imported from Britian must comply with the following guidelines regarding tint and windows:
• British Standard BS 857:1967 Specification for Safety Glass for Land Transport
• British Standard BS 5282:1975 Road Vehicle Safety Glass
• British Standard BS AU178:1980 Road Vehicle Safety Glass
Cars imported from America must comply with these guidelines regarding tint and windows:
• American National Standard ANSI Z26.1-1980 Safety Code for Safety Glazing Materials for Glazing Motor Vehicles Operating on Land Highway.
However this does not mean they can be whatever they like. They must still stick to strict regulations and guidelines, however some things such as windows can be to the regulations from that country, rather than our own strict regulations.
