I'm using the Eibach drag launch kit in my car with lakewood 70/30 struts in the front, and Tokico adjustable shocks in the rear. It drives great on the steet, and there was a noticable improvement in traction as well. If you want to get the most out of a set of drag springs, you really need to remove your front sway bar. The downside of this is that you lose a lot of your ability to take corners, due to increased body roll. The up side is you greatly increase weight transfer to the rear wheels.
