I would suggest downloading them from suprnova.org. Go to Movies at the top and then Automotive/Cars. You'll need a bittorrent client. All the GIS are there but the 3rd. Ghostrider is on the site somewhere too, do a search.
Isn't it easier to use dc++? There you can easily find GIS's from 1 to 4 and all the Ghost Rider clips etc. without bittorrent. Well everyone does what they seem to be the best.
