I just installed these a few days ago and the rear stock endlinks worked, but not up front. Sure you can get them to bolt up when the weight is on the suspension, but there is no clearance between the bottom of the stock end links and the control arms. They will end up bent to hell. I had to get adjustable endlinks for the front... They mad my car into a cornering beast! At the moment I'm just trying to get my stiffness settings dialed in the way I want them. I've all ready got all the endlinks on and got alignment yesterday. The ride is alot different than stock. As would be expected it is a rougher ride than stock. I found the recommended settings a little too soft. Setting them a little stiffer reduced the bounciness (if thats even a damn word, lol) I was experiencing at first.
