Yes I did. The high speed portion of the stack is lighter than stock so it soaks up the small chatter and braking bumps better but the low speed portion is firmed up a good amount to handle the bigger hits. There are definitely improvements to be made in the valving and it is worth doing if that is what you are wondering.Did you ever do your valving? If so how is it and what did you put in?LOL Thanks PK. I just know what I know from doing a ton of reading on the subject and what I have personally tried. I hate all the secrecy regarding spring rates and I love that Eibach is up front with that info. I'm far from a expert though and I have barely scratched the surface in regards to suspension knowledge. Shocks and suspension have always intrigued me. Getting ready to have a good friend of mine do some valving on my shocks so I am hoping to learn a lot more from him. And have my shocks work better of course.....Rynomax knows his stuff!!
