I don't have these, but I saw a post on Facebook where someone had them installed on a Renegade. It looks LOW. I am asking him the drop height, as I didn't see it listed on their site.
Just figured I would let the few people that modify their X know about them. Now, I am really up in the air about what I am doing with my X. I have the Madness springs in my garage, just haven't got around to installing them. But these look very interesting.
