The majority of responses I have seen have all been negative but I don't really know myself. I have Steeda springs.
Kind of interesting though, I don't believe I have seen any of the main Focus parts sites
selling these which makes you wonder why? Is it a quality issue? Or maybe I'm wrong.
I see them on e-bay which for me always sends up a red flag, buyer beware[B)]
I have to say go with Eibach.......I installed their kit in my car and I love the ride, and the stance. Not as low as most people like it, but I'm not the kind that wants to go up driveways at an angle.
shamless plug for the FK stuff again! as far as i know, you can still get all you need for $350 shipped (shocks, struts, and springs). have the 35/40 and love it. great for a daily driver, but maybe a little softer than you'd want for a "race-type" application. lifetime warranty, and TUV approved!
The 2 people I know of who have DropZone springs both ended up with RAISED suspensions after the install. One of these guys ended up cutting 1 coil in the front and 2 in the back just to get it to sit like mine does with the Eibach Pro-Kit.
