I have the FSD's paired up with some H&R sports. It is a much better overall ride. The same bumps that use to throw my car around a bit on the sport package, now get "eaten up" by the selective dampening. It's a great product.
On a side note, I'm parting out my car and have my set for sale! Pm me.
Koni FSD + H&R sports for $350 (About 10k miles on this setup)
