That setup doesn't even stretch a 4door. Idk what that was about. It stretches a 2door though. There have been several discussions about that kit on other forums and the guys that really know what they are talking about all seem to agree that it's a nice kit if you want something that "looks" trick. In reality though, the angles are not there, the separation at the frame between the upper and lower mounts is off and causes instant center and anti squat issues, etc. most will agree when you go as far as that kit requires its best to fab your own setup.
