Ford Racing Lowering N Springs

I have a '14 V6 auto with performance package with only 10k miles on the car and I have been thinking of getting lowering springs because the stock stance has really just been driving me insane lately and I also want the improvement of handling that goes along with it. I have been looking at the Ford Racing N springs wondering if any of you had anything to say about them? I also wanted to know if I really need a new panhard bar if i get new lowering spring?
