Installed the Koni's, these are a huge improvement over OEM. Keep in mind my OEM's had 46k on them. Didn't think that was too bad until I found my front bump stops were shattered at the top. I was probably going to shave them down anyway, but the point is over time I didn't realize I was stressing out my bump stops like that. One install tip, remove the bottom 4" or so of paint on the front struts (enough to fit into the front control arm sleeve.) I could not fit the fronts without taking the layers of yellow off. It's amazing how thick it is, WHY? The tolerance in fitting the struts into the sleeve is slim. I've heard that the FSD's have the similar issue. I'm going to call Koni to see if they can address this. Not sure how much good it will do but can't hurt. The rears are a piece of cake. Put about 70 miles on them today. Overall they feel incredible, can't wait to take them out for the next Autox to see what they can do. Set both rears/fronts to 50% for now and will see how that works out. The fronts are so easy to adjust, the rears unfortunately have to be taken off to adjust, once they're off it's simple. Can't wait to drive tomorrow and start putting some miles on these, ZOOM ZOOM....
