This is exactly what I was looking to find out. Progressive vs linear on coilovers is the cause of the harsh ride issue all my friends talk about. I thought that was something to look out for only on lowering springs. They could never explain it, they all simply said go with springs instead for a nicer ride...and they all have multiple experience with both.

Ive always used springs with new shocks/struts and have been very happy with them. If you want a smoother feel use springs if you want that gokart feel along with the harshness go coilovers.
This leads me to create this thread. Why then is a "true" coilover so great if they come with linear springs? Why not get a coil/spring setup and swap out the springs for a different spring that is progressive? Or get the d2 and swap out the springs for progressive ones? Go to a company like this Summit where they specifically design springs for coils with customizable sizes. Wouldn't that solve all problems? Am I looking at it too simplistically? I wouldn't go this route now because I don't want to deal with the corrosion/rust issues here in NY (because I'm simply not going to add another thing to the list of things I have to maintain on this car), or the squeakyness that seems to pop up over time with coils; but I think it would be a good discussion and exercise for people really interested in coils that crave the progressive style.
