op:I messaged one of the site sponsors (PR Racing I think) about this and he said that some of them aren't authentic VIS products, and even if they are, they won't back up the damaged/warped VIS warranty like they would. PR Racing ended up offering me a price just as good as ebays shipped for a hood & hatch, the extra couple of bucks insures me some sort of warranty. But good luck with that, $535 shipped sounds like a steal.
