[WA] Anyone know the WA laws for suspension and wheels?

[samd]

I have recently moved to Western Australia and bought a VS Commodore, all I want to do is lower it a little bit with a stiffer shock/spring combo and put on some larger alloys (probably factory ones from a later model). I just want to know what the rules are so I can keep it all legit? Cheers

same as everywhere else pretty much, 100mm from the lowest point of the car and 15mm overall rolling diameter increase

Click on my link below for the Road Traffice (Vehicle Standards) Rules. Number 67 tells you about the suspension. Lots of other info for you also;
