holy shit, blast from the f**kin 90's!
belting out a shit ton of music on itunes at the moment, and the last 3 songs it spat out were glycerin by bush, shimmer by fuel, and be quiet and drive by the deftones... f**kin hell, it was awesome.
you lower your car and youre gonna have weird camber. all a part of modded car life. thankfully, camber arms are cheap.
pretty simple procedure, some body shops and most wheel shops (tyrepower, wheeljerx, etc) will roll your guards for $40 a corner.
basically it just involves heating the lip of the guards and knocking inner horizontal lip flush with the skin. gives you a solid half inch clearance.
scrapes arent that bad. as i said, ive only ever had problems out on track, and they were solved with zip ties... you mightnt even have that problem.
youre gonna scrape your exhaust and shit more than anything. andrews just being dramatic.
whats your definition of 'fine'?
offset is pretty simple stuff, theres a bunch of great articles out there, even wikipedia has a page on it.
but yeah, places like jis are happy to help you test fit wheels to your car to see how they look, and places like adelaide tyrepower and wheelworx will be happy to give you a hand.
