The Koni shocks are fantastic but they require some extra work to fit out back. They bolt right in on the front. The Bilstein shocks bolt right in but I prefer the Koni shocks since they are adjustable. I don't know why the Koni engineers screwed up the mounting bolt size on the rear shocks but they did. I build lower shock mounts that work with the Koni shocks so that is an option if you want to use the Koni shocks.
