i can see where the limitation of lowering/raising of vehicles will be beneficial to new cars with dsc(dynamic stability control and the like), as engineers have inputed alot of data, and the car behaves with specific height and sprin rates.
i dont really see the difference its going to make to most cars that are sensibly lowered. i think the current rules of 100mm to road, 1/3 suspension travel, and 600mm to headlights is still quite effective.
and as for the news articlle, it does read as mods after the date will need approval, will they have to prove the lowering was done after the date, or will we be guilty until proven innocent with recipts for work?
as othrs have mentioned though, most of us are probably driving around in defectable cars anyway, so whats the difference?
you can still get your rego cancelled for other defects. just keep a set of standard struts handy, swap them for the inspection, then swap them back. easy
