Just installed Koni Yellow's (inserts). PITA to install, but worth it. I have Eibach Pro springs (1.1" drop) and the car rides like it's not even lowered. There is an adjustment for the dampening rate on each shock. Right now I have it set on the softest setting. I'm gonna try about 1/4 turn to firmer to see how I like it. Ther'ye pricey, $464 shipped from AJUSA.
