I have the kit installed and am satisfied that it does what it is supposed to. The lower ride height is a given, but their claim is to improve handling too. I think they do this quite well but as some expense in ride harshness. I attribute that more to harder shock settings, but since I installed it as a package it's hard to isolate the effects. Certainly I haven't been tempted to switch back. To Modded's point about the front springs - I haven't felt any issues there, but they wind them very progressively to get a balance between ride quality and wheel travel. There is definitely potential for variability in the product when you push the envelope. Another consequence of this is that the top coils have a very narrow spacing that makes it a bear to get a spring compressor in there - actually more to get it out once the spring is in place. Overall evaluation - it's a good kit; I recommend it.
