I know this is an old thread, but it might be the best (only?) source of Elise shock dyno plots out there.Ok, after dynoing my Nitrons and installing them, I dynoed my Bilstein Track Packs just for the heck of it since all I can gather were mostly anecdotes and no actual data.
I've had these 5 years, 25K miles of 60:40 street/track miles on them.
I've been told all along that it's rebound only adjustable, or on the rare occasions, that it's mostly rebound and some compression adjustable. Welp, I can safely say that it's COMPRESSION ADJUSTABLE.
I'm a little confused by your note though. Isn't the top half of that plot rebound, not compression, thus making these mostly Rebound Adjustable?
