nh-tuning.de will ship you B8 which are the 'matched' shock for your springs.
oh, and H&R swaybars or similar would be another option to reduce body roll. With the softish rate of the Eibach springs/B8's I would personally upgrade swaybars. I have used a near identical setup on another car with great success.
There are two schools of thought:
1- Use Shock/Spring to control roll through stiffer rates, use swaybars to set 'balance'
2- Use swaybars to reduce body roll, use softer(relative to point 1) shock/spring to improve traction, grip, braking etc.
I've run Bilsteins and Konis, i don't buy Koni any more.
