Amidst the "xenon" bulb, "tunable" exhaust, and "timing advance kit" drivel (

) on Ebay, there's always a set of slotted SVT rotors for what seems like way too cheap. They're Australian, or something. It's sort of hard to tell what they're about, even in their website. Is anyone familiar with these? Do they fit into the "useless cosmetic upgrade" category, or are they legit?
