Sportline spring questions

So I just bought a set of Sportlines and my question is: Is there anyone who has SUCCESSFULLY put just the springs on with no other mods like CC plates and so fourth?No guessing here, I want to hear from someone who knows. I'm sure I need to put CC plates on at the bare minimum. That is actually my plan, springs, isolators and CC plates. This is my first time to lower a stang so I need some good input. Thanks guys
 
I put them on my car for a little bit with no other mods. They rode and cornered awesome. But my front tire wear was relly horrible so I took them off. They are in storage now and Im waiting to tackle the suspension all at once. Id say put CC plates on with them at the very least.
