My opinion about the progressive coil springs is that for the first amount of travel, the spring is softer than the last amount of travel.

I had a set of "progressive" springs and didn't like the way the car reacted. The first inch or so of travel was soft and became progressively firmer just like I would expect, but I didn't like the fact that you had to "set" the car before it would really feel stable.

I went to linear springs and like it much better. The first inch of travel is almost just like the last. (good to the last drop) (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif)

I think that the way they make those progressive springs is that the "soft" part of the spring has the coils spaced further apart, while the "firmer" portion has the coils spaced closer together. (that might be backwards.....)

In any event, I don't like the variable spring rates in a performance application.

On bumpy streets, however, it might be a good thing.
