They have a 32-way damper adjustment. I set mine to the stiffest level, and it is much stiffer than f-sport springs. I haven't tried the softer damper settings, but from what I've heard, the softer settings are pretty close to the feel of the f-sport springs. I was just personally interested in the best handling/stiffness.looks good. Are they a little stiffer then the F-Sports?
