so whats up with wheel spacers? i want to bump out all 4 tires on my xB but i'm not sure which ones i need. i would like them to be flush with the fender, or barely inside of it...and since they're in the scionlife store for a little over 100, i assume i would be able to find em at half that price if i looked around right? lemme kno what spacers you guys used and your experiences n what not..
