I have a 2013 R56 w/30,000 miles. I want to lower it to improve its stock stance. Not trying to improve the handling, or stiffen the ride. I like the stock ride. To wit, I purchased a set of Eibach lowering springs which are supposed to lower the car by 1.2" front & rear. I am debating replacing the struts & shocks, when I do the job. In my experience with other vehicles (2012 Grand Cherokee 50,000mi), after installing 1" lowering springs, both struts started leaking oil :/ Not sure why this happened, but I'm pretty certain the springs caused the leaks. I'm wondering if this is somewhat common, or maybe its a Jeep thing. IDK. If necessary I will replace the strut/shocks with new ones. Being of reasonable means, I was considering the Bilstein B4 OE replacements. Appreciate your thoughts. Note this is my first post.
