I know a guy with the H&R Super Races on a '96 Cobra vert that runs 1 turn on the street and 1.75 on the course and he seems fine. I know 1/2 a turn on my Konis is about the same stiffness as Cobra R valved Bilsteins, at least that's how it feels on my car. I'm wondering if you have your struts so stiff they are just acting as additional spring rate in the front, bounding and rebounding so little they aren't really doing their job. I know when my one buddy sets his Strange 10-ways too stiff they'll actually support the loading of the car instead of the springs. Either that or the valves are worn out.
