I'm assuming you meant Tokico. If so, yes they are a quality product. I've had Tokico shocks (blues, the non-adjustable ones) on my Civic for a couple of years now, and they've worked extremely well with my H&R OE Sport springs (3/4" drop).
I'm not certain about the Tokico springs, but I would imagine that Tokico probably sources them from one of the major spring manufacturers anyway (possibly H&R or Eibach). I'm sure the spring quality is excellent too, and it's nice to know that both springs and shocks have been designed to work well together.
If you really did mean Toxico, then all bets are off!
