Ripping GT4 car models

[Tenifyz]

Hi, i've been trying to do this for weeks and i could get my hands on a few files, however i'm stuck because i don't know how to convert these files... I wanted to use them for blender, for a few rendering and using it for testing as general.
I've tried to read thru the Ferrari GT thread post, but the images are all gone and i can't seem to find much information on it...
Does anyone have an good tutorial on how to rip the car models?
any help would be really thankful!
