For The Win. And they will set you back around AU$800 + shipping. They are easy enough to fit yourself with a little mechanical knowledge.
A little advice though, If you dont feel comfortible picking up tools to work on a car yourself, then modifying cars is not for you. Paying for other people to do mods for you is rediculously expensive. On my cars, the only things I ever pay someone else to do is glass fitting and tuning - everything else I do with my own hands, so I know its done right (or atleast how I think it should be).
Things like precise machine work are an exception to this rule, obviously.
