I helped put a 2" trans raise in a buddy's car and if your thinking of doing this to a street car I would personally advise against it. You have to cut out alot of sheet metal to do it, modify your fan shroud, and modify your exhaust. I wouldn't want to cut that much out of my car to raise the trans unless you are a very skilled body person and had access to a spod welder, mig or tig welder, and other tools to put the car back together if you didn't like it. Just my 2 cents.
