Hey Josh, According to Vicroads, you only need around 100mm clearance from the lowest point of your car, which give you heaps of options to play with really. IMO, I'd probably invest more in coilovers rather that just springs tho.. but each to there own I guess. but yeah, if your worried about attracting attention from the cops, then you should probably check out the vicroads site before modding anything. If you do happen to get pulled over, just use the same excuse everyone does, that your about to sell it and it's your last drive before the buyer comes picks it up, they usually let you go after that. But yeah, don't use it too often, if it happens and you get away with it, take it as a warning and fix your sh!t before you get pulled over again. Depending on how low you go as well, you might want to take a look at the offset on your wheels as well. IMO lowering your car can make or break it, you probably want the tire to sit flush (if not, almost flush) with the fenders, not too far in or out. This could mean either a new set of rims (legal) or hub adapters (certainly not legal), but yeah. Australia has probably some of the toughest laws regarding this crap, only because it's a nanny state.. you can blame your Techno listening Muzztech Warriors wearing their poofy bumbags on 95 degree angle driving their mums fully sick VN Bombadores, thinking they own the streets for that. In short, try the vicroads site for more info on ride hide and you should be sweet. Best of luck with it tho, man
