Man you guys get it rough in Aus, over here in NZ I drive a very low obviously modified r33 with wheels, adjustables, exhaust (with decat) intake, bov delete, front mount, tints etc and haven't been pulled over in the 18 months I've been driving it. Before that drove a lowered modified Prelude for 6 years and was pulled over once for a random stop...
Mine is the equivalent of engineered so is road legal, and every older car gets checked at 6 monthly roadworthy checks which is the only time I ever have a problem with authority if I have mods they don't like haha. But if I do, the inspection is pretty straightforward to get them legal.
You guys need some better legal representation! Defend your rights!
