Just like everyone has mentioned, springs are a hit and a miss. Everybody has a different idea of what the prefect ride, handling and ride height is including the manufactures. I'm on my third set of springs on my 66 Impala and are maybe, kind of sort of, finally happy. You need to order what you think is the right set, put them in and go from there. That might sound a little rash but its tough getting exactly what you think you want or need.
