It is a major improvement over the torsion bar suspension. (Sorry I know that statement will anger some) I called all 4 guys that make IFS for our cars, I liked Carl the best and bought his IFS. I am thinking about his 4 link rear later on. The install took work as the others will. All parts were shipped. I sat on that kit for 1 year before I installed it. It does not drive anything like before. I have a manual rack. I love it.
