Has anyone used their coilovers? Are they worth while. I was looking at the Kontrol Pro Dampening System let me know thanks.

 

If it's cheap and from a little known company I can guarantee it will either have quality issues or not have the right mix if damping performance or both. Chasing the lowest bidder only set's you up to lower the bar, you may think you've won, but you really haven't. Expand your budget, HKS or Cusco both come to mind, though we really have no clue what your needs are.
