Initial D movies??
There is only one movie out, it's also call Third Stage. And there is a Live action movie in production in China that's not out yet.
Movies? if you meant episodes.. in the download section: www.animeonline.net/showthread.php?t=1144 you could download the latest episodes from fourth stage
or try animesuki: www.animesuki.com/ i'm pretty sure they have them all.
