max effectiveness I'd say go with the Bilsteins for those eibach shocks.... but its not much of a difference from the TOkico really... and for mentioning $50 per shock.... i'd say definitely go with TOkico. I dont know how Koni is with eibach but i'm willing to bet it'll be up there... i have Koni' and Tein....its Great!!!
You'll like the Tokico's. I had mine installed 3 weeks ago and I am very happy with them. I don't race or track my car so adjustable shocks would have been a waste for me. I am sure others will disagree but I got my shocks for $350 installed at my friend's shop.
